R : reading
Phase shift (DC - 65 Hz)
(1) The maximum permitted value is only limited by the cross section of the primary conductor. Saturation
of the magnetic core of the clamp occurs, which is not dangerous. A high residual magnetism may remain
which can be eliminated by demagnetising the clamp.
(2) Outside hysteresis on DC. (Check zero, no conductor in the jaws). The intrinsic error is expressed as:
± (% R + phase shift)
Output signal : 1 mV DC or AC per amp DC or AC
1 V DC or AC per amp DC or AC
Maximum working voltage : 600V rms
Load impedance : > 2 kΩ on the 1 mV/A range
> 10 kΩ on the 1 V/A range
