Operating Instructions
Voltage Measurements
1. Insert the black test lead banana plug into the negative
COM
jack and the red test lead banana plug into the positive
V
jack. 2. Turn the rotary switch to the
V
position. 3. Press the SELECT button to select either AC or DC. 4. Touch the test probes to the circuit under test and read the voltage on the display.
Current Measurements CAUTION
: Do not make high current measurements on the 10A scale for longer than 15 seconds followed by a 15 minute cool down period. Exceeding 15 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative
COM
jack. 2. For current measurements up to 200mA DC, set the function switch to the
µA
or
mA
position and insert the red test lead banana plug into the
mA
jack. 3. For current measurements up to 10A DC, set the function switch to the
10A
range and insert the red test lead banana plug into the
10A
jack. 4. Remove power from the circuit under test, then open up the circuit at the point where you wish to measure current. 5. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the positive side of the circuit. 6. Apply power to the circuit. 7. Read the current in the display.
Resistance Measurements
1. Insert the black test lead banana plug into the negative
COM
jack and the red test lead banana plug into the positive Ω jack. 2. Set the function switch to the Ω position. 3. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading. 4. Read the resistance in the display.

COM
jack and the red test lead banana plug into the positive
V/
Ω
/mA
jack. Observe polarity. 2. Turn the rotary switch to the
•)))
position. 3. Touch the test probes to the circuit or device under test. If the resistance is less than approximately 30 Ω the buzzer will sound.
Diode Measurements
1. Insert the black test lead banana plug into the negative
COM
jack and the red test lead banana plug into the positive
V/
Ω
/mA
jack. 2. Turn the rotary switch to the
•)))
position. 3. Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V. Reverse voltage will indicate “
OL
”. Shorted devices will indicate near 0mV and an open device will indicate “
OL
” in both polarities.
Data Hold
Press the
Hold
button to freeze the reading in the display. “
H
” will appear in the LCD. Press the key again to release the display.
Low Battery
If the + - low battery icon appears in the display, replace the batteries to maintain proper operation.
Auto-Ranging
The meter will auto range to the optimum range to provide the best resolution and accuracy for the input signal.
Auto Power Off
1.
This meter will automatically shut off after approximately 15 minutes of operation. If the meter shuts off, rotate the function switch to OFF and on again (or press the HOLD button) to resume operation.
2.
To disable the auto power off, hold the SELECT button while turning power on or press the SELECT button after auto power off has turned the meter off.
Maintenance
WARNING:
To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery/fuse cover.
WARNING:
To avoid electric shock, do not operate your meter until the battery/fuse cover is in place and fastened securely. This Multimeter is designed to provide years of dependable service, if the following care instructions are performed.
1.
Keep the meter dry.
2.
Use and store the meter in mild ambient conditions. Temperature extremes can shorten the life of the electronic parts and distort or melt plastic parts.
3.
Handle the meter gently. Dropping it can damage the electronic parts or the case.
4.
Keep the meter clean. Wipe the case occasionally with a damp cloth. DO NOT use chemicals, cleaning solvents or detergents.
5.
Use only fresh batteries of the recommended size and type. Remove old or weak batteries so they do not leak and damage the unit.
6.
If the meter is to be stored for a long period of time, the batteries should be removed to prevent damage to the unit.
UL LISTED
The UL mark does not indicate that this product has been evaluated for the accuracy of its readings.
Battery and Fuse Replacement WARNING
: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery/fuse cover. 1. Disconnect the test leads from the meter. 2. Remove the rubber holster (if in place). 3. Remove the two screws securing the rear cover using a Phillips head screwdriver. 4. Batteries: Lift the cover off and replace the batteries observing the correct polarity. Insert the new batteries into the battery holder. 5. Fuse: Remove the old fuse by gently pulling up on it. Install the new fuse by gently pushing it into the holder. Always use a fuse of the proper size and value; 250mA/250V fast blow. 6. Replace the rear cover and secure with the screws. Never dispose of used batteries or rechargeable batteries in household waste. As consumers, users are legally required to take used batteries to appropriate collection sites, the retail store where the batteries were purchased, or wherever batteries are sold.
