OPERATING INSTRUCTIONS CAUTION When making voltage or current measurements, develop the habit of turning off all power to the circuit under test. Connect the test leads at the desired points in the circuit; then turn on the power while taking readings. Turn off the power before disconnecting the test leads from the circuit.
OPERATION PROCEDURES DC Voltage Measurement WARNING: WITH EXTREME CARE WHEN MAKING MEASUREMENTS FOR HUGH VOLTAGE, AND DO NOT TOUCH TERMINAL OR PROBE ENDS. 1. Set the selector switch to the appropriate DCV range to be used. 2. Connect the BLACK test lead to the “-COM” jack and the RED test lead to the “+”...

tester. (This tester can afford the voltage <250V DC/AC rms. for the period of 5 seconds max.) Resistance Measurement WARNING: DO NOT APPLY VOLTAGE TO MEASURING TERMINAL WHILE RANGE SWITCH IS IN OHM POSITION. 1. Set the selector switch to the appropriate Ω range to be used. 2.
CONTINUITY TEST WARNING: DO NOT APPLY VOLTAGE TO MEASURING TERMINAL WHILE RANGE SWITCH IS IN OHM POSITION. Set the selector switch to the BUZZ range. Connect the test leads to two points of circuit. If the resistance is lower than 200 Ohm approx., the Beeper sounds.
Note: If connected incorrectly with the voltage, quickly remove the test leads from the circuit as to avoid the damage to this tester. (This tester can afford the voltage <250V DC/AC rms. for the period of 5 seconds max.) Decibels Measurement 1.
Error Possible cause The multimeter does Are the batteries exhausted? Is the power not work. indicator lit? Check the state of the batteries and the fuse 0.5A. No measurements Is the fuse defective? Check the fuse 0.5A (fuse possible via V/mA replacement) socket.
