Essential for alarm installers, the ACT CA60 will register low mA current
readings without the need for disconnecting circuit wires. Used with
your own multimeter it will measure milliamps as well as amps.

mA Current Clamp
Operation

The AC/DC mA Current Clamp is a transducer which will allow your
multimeter to measure low electrical and/or electronic current up to
60 Amperes AC/DC, with a frequency response up to 20kHz. When
measuring current with this clamp, there is no need to break a circuit or

to aect the isolation.

The extended measurement jaws allow performing measurements in
a narrow space. When measuring DC current, a simple operating push
button is designed for zero adjustment. The clamp adapter is applicable
to leakage detection or monitoring.

How to take DCmA Alarm Current Readings

1. Plug clamp leads into multimeter COM and DC Voltage sockets and
switch on

2. Switch multimeter to DC mV range

3. Switch clamp to 1mV/10mA range

4. Hold clamp steadily over the wire

5. Press clamp ZERO button until meter reads zero

6. Close clamp jaw over the negative DC wire to PIR/KEYPAD/LIM.
Example: 1.5mV=15mA, 15.0mV=150mA

7. For DC Amps, switch clamp to 10mV/100mA range, press ZERO and
close jaw over negative DC wire. Example: 15.0mV=1.50Amps

mA Current Clamp
Operation

Application Procedures

1. Insert the BLACK banana plug into the COM jack and the RED

banana plug into the VΩ jack 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. The GREEN LED will light to indicate that the clamp is
switched on.

3. For current measurements below 2A, set the unit to 1mV/10mV
range and set the multimeter to 200mVAC range for AC current
measurements, or 200mVDC range for DC current measurements.
If the measured current exceeds 2A, set the unit to 1mV/100mA
range.

4. When performing DC current measurements, always push the zero
adjustment button on the clamp until the multimeter reads zero.

5. Clamp the jaws around the current - carrying conductor and
interpret the reading according to Step 3 above.

6. When 1mV/10mA range of clamp until is selected, multiply 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, multiply the reading displayed on the multimeter
by ‘100’ for interpreting the measured current value in mA. For
example, if the multimeter reads 5mV, the measured current is
5x100=500mA.

Application Notes

1. In the case of DC current, the output is positive when the current

ows from the upsde to the underside of the clamp. The RED

banana plug end is positive.

2. In the case of DC current measurement, a hysteresis eect can
occur so that it is impossible to zero the clamp properly. To

eliminate this eect, 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 conductors or
conductors with cracked or frayed insulators are forbidden.
