INTRODUCTION The AC/DC mA Current Clamp is a transducer which will allow your multimeter to measure low electrical or/and elec- tronic 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 affect the isolation.
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.
When the unit is connected to a DMM which accuracy is supposed to be 0.5% in 200mV range,the reading displayed on the DMM will be 10.25mV max. (10.20mV x (1+0.5%)=10. 25mV) and 9.75mV min. (9.80mV x (1-0.5%)=9.75mV) Current Clamp Accuracy DCA range: 1mV/10mA ±...
