OPERATION PROCEDURES DC Voltage Measurement WARNING: WITH EXTREME CARE WHEN MAKING MEASUREMENTS FOR HUGE VOLTAGE. 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 “+”...

The Maximum terminal voltage drop is 250mV except for the 10A range. Note: If connected incorrectly with the voltage at these ranges, quickly remove the test leads from the circuit as to avoid damage to this 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...
Diode Measurement 1. Set the selector switch to the appropriate Ω range to be used. NOTE: To test the diode while current below 0.060 mA at X 10K range; current below 0.15 mA at X 1K range; current below 1.5 mA at X 100 range;...

Decibels Measurement Set the selector switch to AC 10V range. Connect the BLACK test lead to the “-COM” jack and the RED test lead to the Red “+” jack. Connect the test leads to the measuring circuit specially in series with a 0.047μF/400V Metalized Polyester Capacitor. And then read the bottom Red dB scale.

1. For Measuring the Capacitor over 25uF: Set the selector switch to the R X 1K range. Connect the BLACK test lead to the “-COM” jack and the RED test lead to the Red “+” jack. Connect the test leads to the capacitor to be measured (Note the polarity of capacitor).
Troubleshooting Nevertheless, problems or malfunctions may occur. For this reason, the following is a description of how you can eliminate possible malfunctions yourself: Error Possible cause The multimeter does Are the batteries exhausted? Is the not work. power indicator lit? Check the state of the batteries and the fuse 0.5A.

MAINTENANCE Replacement for Battery and/or Fuse should only be done after the test leads have been disconnected and POWER OFF. 1. Battery Replacement 1). Note the condition of the batteries using the procedure described above, if the battery needs to be replaced, remove the screw and open the upper cover of the battery cabinet on the rear case.
