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. Set the selector switch to AC 10V range.
2.
Connect the BLACK test lead to the “-COM” jack and the RED test lead
to the “Output” jack.
3. Connect the test leads to the measuring circuit, and then read the bottom
Red dB scale.
4.
For more dB scope, change the selector switch to the others of ACV
ranges and make the same actions. Add the appropriate number of dB
scale reading as noted on the chart below.
Note: For absolute dB measurements, circuit impedance must be 600
Ohm. 0 dB = 1mw dissipated in a 600 Ohm impedance (equivalent
to 0.755V across 600 Ohm)
ACV RANGE ADD dB Number
50 14
250 28
1000 40
Capacitance Measurement
WARNING: DO NOT APPLY VOLTAGE TO MEASURING TERMINAL WHILE
MAKING ANY CAPACITANCE MEASUREMENTS
.
BEFORE TESTING ANY CAPACITORS, DISCHARGE THE CAPACITOR
COMPLETELY.
1. Set the selector switch to the
Ω X 1K range.
2.
Connect the BLACK test lead to the “-COM” jack and the RED test lead
to the Red “+” jack.
3. Connect the test leads to the capacitor to be measured (Note the polarity
of capacitor).
4. Watch the needle deflection to the right topside, and read the Red C
scale on the Dial.
TROUBLESHOOTING
Nevertheless, problems or malfunctions may occur.
For this reason, the following is a description of how you can eliminate
possible malfunctions by yourself:
