OPERATION PROCEDURES
DC Voltage Measurement
WARNING: USE EXTREME CARE WHEN MAKING
MEASUREMENTS FOR HIGH 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
“+” jack.
3. If measuring a voltage above 1000V, insert the red test lead into the “2500v”
jack.
4. If you know the polarity of the circuit to be tested, connect the black probe to
the negative side.
5. If you don’t know the polarity, connect the probes to opposite sides of the
circuit and watch the pointer. If it goes to the left, reverse the probes. The RED
probe will be connected to the positive.
6. Check the needle position and the get the reading on V.A scale.
AC Voltage Measurement
WARNING: USE EXTREME CARE WHEN MAKING
MEASUREMENTS FOR HIGH 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. If measuring a voltage above 1000V, insert the red test lead into the “2500v”
jack.
4. Check the needle position and the get the reading on V.A scale.
Note: Measuring high voltage at 2500V range, should be wear rubber
insulated gloves on both hands and be in a dry insulated environment.
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.
