AC Current Clamp Adaptors Model 8104

Introduction
The Model 8104 is clamp-on AC current to
voltage transducersthat permit your digital
multimeters or recorders to measure
AC current up to 3000A.

Features
The model is available for different application
needs,depending on a current to be measured
and the size of a current carrying conductor.

Specifications (at -13℃to +33℃, 85% relative humidity maximum 45Hz to 65Hz frequency)

Measuring Ranges	0 - 30/150/300/1500/3000A AC
Rated Output	0 - 150mV AC for all ranges
Accuracy	±2% of rated output for 0 – 300A±4% of rated output for 1500 –3000A
Operating Temperature & Humidity	-10℃ to +50℃, 85% relative humidity maximum
Measurement Time	Continuous for all range at an ambient temperature of+30℃ maximum
Output Cord	5m long, terminated with 4mm-dia banana plug
Output Polarity	When DC current flows from the upside to theUnderside of the clamp, the red banana plug is positive.
Dimensions	310(L) x 150(W) x 29(D) mm
Weight	950g approx.
Conductor Size	100 mm

Operation (For use with a clamp on AC current recorder refer to operating instructions supplied with it)

Preparation

With the output cord of the clamp adaptor connected to a digital miltimeter (AC voltmeter)
having a minimum input impedance of 100kΩ, set the clamp adaptor range switch to the
highest range and the digital multimeter range to 200mV AC or 2V AC.
Press the adaptor jaw trigger to open the transformer jaw and clamp on an AC current
carrying conductor. Take the multimeter reading in amperes directly or multiply it by a proper
factor. Where input is a smaller current, change the adaptor range switch position for lower
range.

Examples:
