APPLICATIONPROCEDURES
1. Insert the black banana plug into the COM jack and the red
banana plug into the V-Ωjack of any multimeter with
a minimum input impedance of 10k ohms.
2. Set the power switch from “OFF” to the desired range,
1mV/10mA or 1mV/100mA position. The green LED will
light to indicate that the clamp is switched on.
3. For current measurement below 2A, set the unit to 1mV/
10mA range and set the multimeter to 200mV AC range for
AC current measurements, or 200mV DC range for DC
current measurements. If the measured current exceeds
2A, set the unit to 1mV/100mA range.
4. When perform DC current measurement, always push the
zero adjustment button on the clamp until the multimeter
reads zero.
5. Clamp the jaws around the current-carring conductor and
interpret the reading according to Step 3 above.
6. When 1mV/10mA range of clamp unit is selected,
multiple the reading displayed on the multimeter by “10”
for interpreting the measured current value in mA. For
example, if the multimeter reads 10mV, the measured
current is 10x10=100mA.
When 1mV/100mA range is selected, multiple the reading
displayed on the multimeter by “100” for interpreting the
measured current value in mA. For example, if the multim
eter reads 5mV, the measured current is 5x100=500mA.
APPLICATION NOTES
1.In the case of DC current, the output is positive when the
current flows from the upside to the underside of the
clamp. The red banana plug is positive.
2.In the case of DC current measurement, a hysteresis ef-
fect can occur so that it is impossible to zero the clamp
properly. To eliminate this effect, open and close the jaws
several times and push zero adjustment button.
OPERATOR SAFETY
1.Do not clamp around conductors with voltages equal to or
exceeding 300VDC or 240V rms AC.
2.To avoid physical injury, measurements on bare conduc-
tors or conductors with cracked or frayed insulator are
forbidden.

Effective Measurement Range
1mV/10mA: 10mA to 20A DC or rms AC for 200mV range
of the multimeter.
1mV/100mA: 10mA to 20A DC or rms AC for 200mV range
of the multimeter.
20A to 60A DC or rms AC for 2V range of the
multimeter.
Accuracy
System accuracy: Current clamp accuracy + DMM
accuracy.
For example, if the measured conductor carrys a
100mA current, set the current clamp to 1mV/10mA
range to get an output signal of 10mV. Suppose the
accuracy of the units is 2.0%, the tolerance limit
should be between 10.20mV maximun and 9.80mV
minimum.
