AC Vp-p:
1. Set the selector switch to the appropriate Red ACV range in the
parentheses (28， 70x2， 700， 2800); and connect the test
leads across the circuit or load under measurement. (Polarity of
the test probes is unimportant.)
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 the
special 3rd Red ACVp-p scale.
NOTE: at AC50V(70x2) range， the actual Vp-p value must be
multiplied by twice the reading at 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.
The Maximum terminal voltage drop is 250mV except for the
10A range.
