Fm Page 5 Friday, August 6, 1999 1:25 PM A WORD ABOUT SAFETY We have taken every precaution in designing this meter to ensure that it is as safe as we can make it. But, safe operation depends on you, the operator. We recommend that you follow these simple safety rules:.

Never apply voltages to the meter that exceed the limits given in the specifications. Never apply more than 1000V DC or 750V RMS AC between the input jacks and ground. Use extreme caution when working with voltages above 100V. Always disconnect power from the circuit you are measuring before you connect test leads to high-voltage points. Never connect to a source of voltage when you select the diode check, resistance measurement, or current measurement function. Always discharge any capacitors of the circuit under test before you attach test leads. Always turn off power and disconnect the test leads before you replace the meter’s batteries or fuse.

Never operate the meter unless its back cover is in place and fully closed. Fm Page 6 Friday, August 6, 1999 1:25 PM. This equipment is rated for installation category II (maximum 3600 VA). Because many AC/DC sets have a potentially hot chassis, be sure the top of your workbench and the floor underneath it are made of non-conduc- tive materials. This meter is fully calibrated and tested. Under normal use, no further adjustment should be nec- essary. If the meter requires repair, do not try to adjust it yourself.

Take it to your local RadioShack store. WARNINGS:. USE EXTREME CAUTION IN USE OF THIS DEVICE.

Fm Page 12 Friday, August 6, 1999 1:25 PM PREPARATION INSTALLING/REPLACING BATTERIES Your meter requires two AA batteries for power. We recommend alkaline batteries, such as RadioShack Cat. Warnings:.

To avoid electrical shock, disconnect both of the meter’s test leads from any equipment before you install or remove the meter’s batteries. Do not operate your meter until batteries are prop- erly installed and the battery compartment cover is in place and secured. Cautions:.

Use only fresh batteries of the required size and recommended type. Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.

Press POWER to turn off the meter if it is on, then disconnect the test leads If they are connected. Fm Page 13 Friday, August 6, 1999 1:25 PM 2. Use a Phillips screwdriver to loosen the screw in the battery compartment cover, then lift off the cover. Install the batteries in the battery compartment as indicated by the polarity symbols (+ and -) marked inside. Replace the cover and secure it with the screw. When BATT appears on the left side of the display, re- place both batteries.

BATT A A A A 13 22-803. Fm Page 14 Friday, August 6, 1999 1:25 PM Cautions:.

Always remove old or weak batteries. Batteries can leak chemicals that can destroy electronic parts. Dispose of batteries promptly and properly. If you are not going to use the meter for a few weeks, remove the batteries.

CONNECTING THE TEST LEADS The test leads supplied with your meter are rated for 1 000 volts. Use only test leads of the same rating with the meter.

You can order replacement leads from your local RadioShack store. Plug the red test lead’s right-angled end into the meter’s + jack, then plug the black test lead’s right- angled end into the meter’s —COM (common) jack. Fm Page 15 Friday, August 6, 1999 1:25 PM Black Test Lead Warning: Always turn off power to the circuit you are about to measure before you probe the test leads into high-voltage points. Caution: Be sure to select the correct function before you touch the test leads to the circuit or component to be tested.

Fm Page 16 Friday, August 6, 1999 1:25 PM USING THE METER Caution: Do not try to measure voltage greater than 1000V DC/750V RMS AC. To use the meter, press POWER to turn it on.

All the display elements briefly appear. Use the selector to switch between the meter’s func- tions. Then connect the test leads to the circuit you want to measure.

To measure different circuits, see “Making Measurements” on Page 19. OL (overload) appears, the value you are measuring exceeds the meter’s maximum range. This is normal when you measure resistance or a diode, or do not have the leads connected to a component.

If you are measuring voltage or current, immediately dis- connect the probes from the circuit. Your meter automatically sets itself to the range that gives the best reading.

See the unit of measure on the display to distinguish the range. For example, mV ap- pears in the 400 mV range and V appears in the 400 V range. 16 22-803.fm Page 17 Friday, August 6, 1999 1:25 PM Also, note the position of the decimal.

For example, if.000 V appears, the meter is set to measure less than 4 volts. If 0000 V appears, the meter is set to measure up to 1 000 volts.

Read the range In volts, ohms, or amps as Indicated by the position of the decimal point. Switch Setting Range Display AC / DC V ' 400 mV ddd.

The display might show a phantom reading in some DC and AC voltage ranges when the test leads are not connected to a circuit.

This is nor- mal. The high input sensitivity produces a “wan- dering” effect. When you connect the test leads to a circuit, a real measurement appears. Your meter conserves power by automatically turning off about 30 minutes after the last time you changed settings (even if you are making mea-.g surements). To turn the meter back on, press POWER. Fm Page 19 Friday, August 6, 1999 1:25 PM MAKING MEASUREMENTS MEASURING DC/AC VOLTAGE Warnings:.

Never clamp on to a hot wire (usually red, black, or blue in AC wiring circuits). If one lead is clamped to a hot wire and you touch the meter’s other probe, you could receive an electric shock. The maximum input limit for voltage measurement is 1000V DC or 750V AC (RMS). To avoid electri- cal shock and damage to the meter, never try to measure a DC voltage above 1000 volts or an AC voltage above 750 volts RMS. Note: When you select ^ or the display might show small changes in lower ranges (such as 400 mV or 4 V) before you connect the test leads to a circuit under test.

This is normal. A high input impedance pro- duces this wandering effect. When you connect to a circuit, you get the normal accurate measurement. Follow these steps to measure DC or AC voltage. Press POWER to turn on the meter.

Set the selector to (to measure DC voltage) or '5P (to measure AC voltage). Fm Page 20 Friday, August 6, 1999 1:25 PM 3. Touch the test leads to the circuit you want to test.

The meter automatically moves to the range that gives the best reading. When you measure AC voltages, and V or mV appear on the display. I I II 'I I IJI.

Fm Page 21 Friday, August 6, 1999 1:25 PM Note: In the 400 V and 400 mV ranges, the deci- mal point appears in the same position (one place to the left). To distinguish between the two ranges, mV appears in the 400 mV range, and V appears in the 400 V range.

A A A A When you measure DC voltages, appears on the left side of the display if you connected the black test lead to a point in the circuit that has a higher voltage potential than the point where you connect the red test lead. 22-803.fm Page 22 Friday, August 6, 1999 1:25 PM 22-803. Fm Page 23 Friday, August 6, 1999 1:25 PM Warning: To avoid injury or damage to your meter, never try to measure an AC voltage that is riding on a DC source bias where the peak voltage exceeds 1 0OV with respect to earth ground.

Caution: Never try to measure any voltage more than 30V AC on a DC source bias. Press POWER to turn on the meter.

To measure the DC voltage, set the selector to Then touch the test leads to the circuit you want to test. The display shows the DC voltage. Disconnect the test leads from the circuit. To measure the AC voltage, set the selector to then connect a 0.1 microfarad/100 V Mylar® capacitor in series with the positive terminal of the voltage source and the positive (+) test lead. Touch the negative (-) test lead to ground. The display shows the AC voltage.

When you finish measuring the AC voltage, dis- connect the capacitor you connected in Step 4. Fm Page 24 Friday, August 6, 1999 1:25 PM Measuring Three-Phase AC Voltage We designed this meter primarily to measure house- hold AC voltages. It is not intended for commercial or industrial use.

If you want to measure 3-phase, line-to- line voltages, please note the following:. 2018 ford cargo van manual. Because of the dangers inherent in measuring three-phase circuits, we strongly recommend you do not use this meter for such applications.

The actual voltage can be greater than the cir- cuit’s rated line-to-ground voltage. To determine if a line-to-line 3-phase voltage exceeds the rating of this meter, multiply the rated line-to- ground voltage by 1.732 (the square root of 3). For example, if the rated line-to-ground voltage is 462 volts, the line-to-line voltage is 462 x 1.732 = 800 V AC. This voltage exceeds the meter’s rating.

Therefore, you should not connect the meter to this circuit or to any equipment connected to the circuit. Doing so could present a dangerous shock hazard to you, and could also damage the meter.

Fm Page 25 Friday, August 6, 1999 1:25 PM MEASURING DC CURRENT To measure current, you must break the circuit and use alligator clips to connect the test leads to two cir- cuit connection points. The connection must be in se- ries with the circuit under test. Caution: Never connect the leads across a voltage source. Doing so can blow the fuse In the meter or damage the circuit under test.

The maximum Input lim- it for DC current measurement is 400 mA. Press POWER to turn on the meter. Set the selector to ^. Remove power from the circuit under test and dis- charge all capacitors. Connect the meter’s test leads In series with the circuit. Fm Page 26 Friday, August 6, 1999 1:25 PM Warning: Do not apply voltage to the test leads while the selector Is set to The connection must be in series with the current. Apply power and read the current.

If the measured current’s polarity is negative, ap- pears before the value. Note: The S range Is fuse-protected. If the meter does not show a reading In this range, check the fuse (see “Replacing the Fuse” on Page 35). MEASURING RESISTANCE The resistance measuring circuit in your meter com- pares the voltage gained through a known resistance (internal) with the voltage developed across an un- known resistance. Warning: Be sure the circuit under test has all power removed and any asseclated capacitors are fully dis- charged before you make a resistance measurement. 26 22-803.fm Page 27 Friday, August 6, 1999 1:25 PM Resistance Cautions: When you measure resistance, the meter supplies voltage and current to the device you are measuring. The current applied by the meter could damage some devices (such as some integrated circuits).

This table lists each of the meter’s ranges and the volt- ages and current that the meter supplies in each range. For each range, A is the open circuit voltage supplied by the meter, B is the voltage supplied by the meter when the resistance being measured is equal to the range the meter is in, and C is the current supplied by the meter. (All values are measured at the meter’s jacks and are typical.) Range A B C 400 W 2.99 V 315 mV 760 mA 4KW 0.86 V 183 mV 335 mA 40 KW 0.58 V 164 mV 50 mA 400 KW 0.57 V 165 mV 5.7 mA 4 MW 0.53 V 165 mV 0.5 mA 22-803. Fm Page 28 Friday, August 6, 1999 1:25 PM Caution: Before using the meter to measure a de- vice’s resistance, check the device’s voltage toler- ance. Follow these steps to measure resistance. Press POWER to turn on the meter. Set the selector to KW.

Caution: Your meter has a circuit to protect the resistance range from over-voltage (240V RMS AC for 1 minute). However, to prevent accidentally exceeding the protection circuit’s rating and to ensure a correct measurement, never connect the test leads to a source of voltage while the selector is set to KW or -tX-.

Note: With no resistance connected across the test leads (the measured value exceeds 4 MW),. OL appears when you set the selector to KW. This is normal.

Fm Page 29 Friday, August 6, 1999 1:25 PM 3. Touch the test leads across the circuit you want to measure, or remove one of the leads of the com- ponent you want to measure from its circuit and touch the test leads across the component.

The meter automatically moves to the proper range. Notes:. If you are measuring resistance of about 1 MW or more, the display might take a few seconds to sta- bilize. This is normal. As with the voltage range, use the measuring units that appear on the display to determine the current resistance range.

If only W appears, the values of the measurements are in ohms. If K and W appear, the meter is measuring kilohms (the reading x 1000). If M and W appear, the meter is measuring megohms (the reading x 1,000,000). When you touch the ends of the test leads together, the meter selects the 400 W scale and displays a small value. This value is the resistance of the test leads and fuse.

Note this value and subtract it from the measured value when yeu measure a very small resis- tance. Fm Page 30 Friday, August 6, 1999 1:25 PM CHECKING DIODES This measurement lets yeu check diodes, transistors, and other semiconductors for opens, shorts, and nor- mal operation. It also lets you determine the forward voltage and polarity for diodes. (This is handy when you need to match a diode.) You can also check LEDs using this procedure. Caution: Do not connect the test leads to a source of voltage when you set the selector to -CE.

This could damage the meter or the circuit being tested. Set the selector to You see. OL: T — TTT 2. Remove power from the circuit under test.

Connect the test leads to the device you want to check, or remove one of the leads of the compe- nent you want to measure from its circuit and con- nect the test leads to the component. Fm Page 31 Friday, August 6, 1999 1:25 PM 4.

Reverse the test leads and note the second read- ing. This table shows the type and condition of the tested semiconductor device.

Semicon- ductor Type 1st Reading 2nd Reading Condition Germanium 0.2- 0.4.OL Good Silicon Type 0.5- 0.7.OL Good Germanium/ Silicon.OL.OL Open Germanium/ Silicon Very small (about 0.1 V) Very small (about 0.1 V) Shorted 22-803. Fm Page 32 Friday, August 6, 1999 1:25 PM Notes:. When you test a silicon type semiconductor, the values might vary depending on the temperature. The values that appear during the diode check show the actual forward voltage (max. If the voltage exceeds 2.0V,. OL appears and the diode check cannot be made. Many diodes have a stripe or mark on one side.

The marked side of the diode indicates the diode’s cathode or negative (-) side. The other side is the anode or positive (+) side. Cathode Diode, Anode - ^ ^ ^ + If a diode is not marked, you can use your meter to check the diode’s polarity.
