AC 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 ACV range to be used

and connect the test leads across the circuit or load under
measurement. (Polarity of the test probes is unimportant on
ACV test.)

2. Connect the BLACK test lead to the “-COM” jack and the RED

test lead to the“+” jack.

3. Check the needle position and the get the reading on V.A scale.

DC Current Measurement

WARNING: DO NOT APPLY VOLTAGE TO MEASURING
TERMINAL WHILE RANGE SWITCH IS IN CURRENT
POSITION. DO NOT ATTEMPT TO MEASURE AC CURRENT.

1. Set the selector switch to the appropriate DC mA range to be

used and connect the test leads in series with the circuit or the
load under measurement. If the pointer deflects to the left,
reverse the probes.

2. Connect the BLACK test lead to the “-COM” jack and the RED

test lead to the Red “+” jack for Current at/less than 0.25A. For
large current max. 10A, move the red test lead to the Red “10A”
jack.

3. Check the needle position and the get the reading on V.A scale.

Note:
Excessive current input across mA range will blow the fuse
that must be replaced by a same fuse rating 0.5A/250V or
10A/250V. The max. testing time shall be not more than 1min.
for big current load.
