ACT Meters CA60 mA Current Clamp - Manual (Page 3)

CA60
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.
