Clamp Current Test (
) (GT-800 only)
The test with the external clamp adapter measures the current in clamped
conductor. The function is intended to measure:
The protective conductor current (earth leakage current) in the protective
conductor (PE).
The load current in line (or neutral) conductor.
Remarks:
Connect the clamp according to the figure 23, 24 or 25.
Select appropriate measurement range by using menu key “RNG” (F1) (0 ...
20 mA for leakage current or 0 ... 60 A for load current).
