Note:
Before dc current measurement, press and hold down the ZERO button for several
seconds for zeroing.

Set the multimeter to the desired dc
voltage range
Note:
Do not set the multimeter to ac
voltage range because the internal circuit of
the Current Probe changes the ac current
signal into dc voltage during ac current
measurement
2. Insert the Current Probe’s two output
plugs to the voltage input terminals of the
multimeter.
Note:
The black output plug must be connected
to the
"COM"
terminal of the multimeter
3. Set the Current Probe to the desired
range with the range switch, the LED lights
4. Select ac or dc current measurement with the AC/DC button according to the indication of
the marks beside the AC/DC button of the Current Probe
5. Before dc current measurement, press and hold down the ZERO button of the Current
Probe for several seconds for zeroing.
6. Press the trigger and clamp the jaws around the conductor to be tested. Make sure that the
jaws are perfectly closed.
Note:
a. Each time only one conductor should be clamped.
b. The conductor should be in the center of the jaws and perpendicular to the
Current
Probe.
7. Read the voltage reading on the display of the multimeter. Then calculate the current of
the conductor by using the formula:
I
= Reading
Sensitivity
(In this formula, is the current of the conductor, reading is the voltage reading of the
multimeter, Sensitivity is the sensitivity of the selected range of the Current Probe.)
Note:
1. Do not input voltage to the output plugs of the Current Probe.
2. For DC current measurements, the display of the multimeter will also indicate the
measured current’s direction.A positive reading (negative sign �-� doesn’t appear ) indicates
that the current direction is from the Current Probe’s front to its back.( Tip: Current direction
is the opposite of electron flow direction.)
3. Each time after you finish a measurement and remove the jaws from the conductor under
test, there may be a residual reading on the display. This reading must be subtracted from the
measurement you just performed.

When the battery’s voltage is less than
about 6.8V, the LED lights red indicating
that the battery is not high enough
and should be replaced immediately.
Maintenance
Except replacing battery, never attempt to repair or service the Current Probe unless you are
qualified to do so and have the relevant calibration, performance test, and service instructions.
The Current Probe should be stored in dry place when not in use. Don’t store it in intense
electromagnetic field environment.
Periodically wipe the case with a damp cloth and detergent, do not use abrasives or solvents.
If you don’t use the Current Probe in along period, remove the battery from it.

1. This manual is subject to change without notice.
2. Our company will not take the other responsibilities for any loss.
3. The contents of this manual can not be used as the reason to use the Current Probe for any
special application.
