Appendices (response graph)
The E3N clamp is a current probe for oscilloscope which uses a Hall effect cell for the
measurement of DC or AC current without modification of the installation (without switching
off the circuit)
It can measure currents from 50 mA to 100 A peak.
It has 2 ranges and 2 lights indicating:
- "ON", correct power supply to the clamp,
- "OL", overload of the range in use (saturation or peak).
In addition a thumbwheel can be used to reset zero for adaptation to the measu-rement
environment.
This clamp adapts to all measurement instruments which have a BNC input and an impedance
of 1MΩ, < 100 pF.
Switch
The switch has 3 positions:
- Off: The clamp is no longer supplied with power
- Range 10 mV/A: measurement of DC or AC peak currents on the basis of 10 mV per
ampere.
- Range 100 mV/A: measurement of DC or AC peak currents on the basis of 100 mV per
ampere.
This range increases the sensitivity of the clamp whilst reducing the measurement extent.
