I. Features:
Plugs into any brand DMM with 400mV or 2V input range for non-contact current monitoring and
wave form pick- up
1.2” (30mm) clamp jaw opening
Measures DC Current when DMM in DC rang and AC current in to AC range
One touch “Auto Zero” for DCA measurements
II. Panel Description
1. Transformer Jaw
This is used to pick up current signal. To measure DC/AC current, The jaw must be enclosed.
2. Transformer Trigger
This is used to open the jaw.
3. Function Selector Switch
This is used to select the function user desired, such as DCA, ACA measurement or turn the
meter OFF.
4. Zero Button
Once this button is pressed, the current reading shall be set to zero. The function is also used
to remove offset value caused by the residual magnetism remained in the core for the dc
current measurement.
5. Power ON/OFF LED display
6. Low Battery LED indication
When the LED lamp turns on, the battery should be changed. Refer to Section V for battery
replacement
7. Output Terminal –
This terminal is used as output for DCA - polarity and ACA. (No input)
8. Output Terminal +
This terminal is used as output for DCA + polarity and ACA. (No input)
9. Hand Strap
Put your hand through the hold of hand strap to avoid.

IV. Operation Instructions
DC Current Measurements:
a. Set the rotary switch at 200A DC or 600A DC.
b. Push the Zero Button to set the reading zero. If cannot, release the button a while and push it
again.
c. Press the trigger to open the jaw and fully enclose the conductor to be measured. No air gap is
allowed between the two half jaws.
d. Connect the test leads to the output shock of the clamp probe and input shock of the DMM.
e. Turns on the DMM and set it at DCV 400mV or 2V range.
f. Read the measured value from the DMM LCD display.
g. Make sure that the offset value caused by the residual magnetism is still removed. If the new offset
value is produced, remove it with the zero button and make a new measurement again according to
the “c” and “d” (If the current to be measured is larger than the current to be measured before, or
the direction of current changes, the new offset value will be produced)
AC Current Measurements:
a. Set the rotary switch at200A AC or 600A AC.
b. Press the trigger to open the jaw and fully enclose the conductor to be measured. No air gap is
allowed between the two half jaws.
c. Connect the test leads to the output shock of the clamp probe and input shock of the DMM.
d. Turns on the DMM and set it at ACV 400mV or 2V range.
e. Read the measured value from the DMM LCD display.
V．Battery Replacement
When the low battery LED lamp is turned on, replace the old battery with new one.
a. Turn the power off and remove the test leads from the clamp mater.
b. Remove the screw of the battery compartment.
c. Slide off the old battery.
d. Remove the old battery
e. Insert one 9V NEDA1604, IEC6F22 battery.
f. Replace the battery compartment and secure the screw.
