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 Red “+” jack.
3.
Connect the test leads to the measuring circuit specially in
series with a 0.047
μ
F/400V Metalized Polyester Capacitor.
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)

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
C
(R X1K) 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 C2000uF scale on the Dial.
