BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery door. 1. Disconnect the test leads from the meter. 2. Remove the protective rubber holster (if installed). 3. Open the battery door by loosening the screw using a Phillips head screwdriver. 4. Insert the battery into battery holder, observing the correct polarity. 5. Put the battery door back in place. Secure with the screw. WARNING: To avoid electric

OPERATING INSTRUCTIONS WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. 1. ALWAYS turn the function switch to the OFF position when the meter is not in use. 2. If “OL” appears in the display during a measurement, the value exceeds the range you have selected. Change to a higher range. NOTE: On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, ch

AC VOLTAGE MEASUREMENTS WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it. Make sure the probe tips are touching the metal contacts inside the outlet before assuming that no voltage is present. CAUTION: Do not measure AC voltages if a motor on the circuit is bei

DC CURRENT MEASUREMENTS CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 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 highest DC 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 th

RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. 1. Set the function switch to the highest $# position. 2. Insert the black test lead banana plug into the negative (COM) jack Insert the red test lead banana plug into the positive $ jack. 3. Touch the test probe tips across the circuit or part under test. It is best to

DIODE TEST 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode jack. 2. Turn the rotary switch to the / •))) position. 3. Touch the test probes to the diode under test. Forward voltage will indicate 400 to 700mV. Reverse voltage will indicate “I”. Shorted devices will indicate near 0mV. Shorted devices will indicate near 0mV and an open device will indicate “I” in both polarities. BATTERY TEST 1. Insert
