4. Application Procedures
P 4250:
1. Insert the black banana plug into the COM jack and the red
banana plug into the V- jack of any multimeter with a minimum
input impedance of 10 k.
2. Set the power switch from "OFF" to the desired range, 1 mV/10
mA or 1 mV/100 mA position. The green LED will light to indicate
that the clamp is switched on.
3. For current measurements below 2 A, set the unit to 1 mV/10 mA
range and set the multimeter to 200 mV AC range for AC current
measurements, or 200 mV DC range for DC current
measurements. If the measured current exceeds 2 A, set the unit
1 mV/100 mA range.
4. When perform DC current measurement, always push the zero
adjustment button on the clam until the multimeter reads zero.
5. Clamp the jaws around the current-carrying conductor and
interpret the reading according to step 3 above.
