1.
Overview
The MP770291 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 indication:
-“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 measurement
environment.
This clamp adapts to any measurement instruments which have a BNC input and an
impedance of 1MΩ,
﹤
100pF.
