(zero corrected)
Resolution
Note (1) The display indicates "+OL" above 3000A and "-OL" below -3000A
in REL mode. The "-" and "+" signs are displayed.
Note (2) The residual current at zero depends on the remanence. It can be
corrected by the "DC zero" function of the HOLD button.

Range
Accuracy ± (1% R +10cts)
Resolution 0.01A
Note (1) The display indicates "OL" above 1500A (in PEAK mode). The "-" and
"+" signs are not managed.
- Bandwidth in AC = 2 kHz
Note (2) In AC, any value between zero and the min. threshold of the
measurement range (0.15A) is forced to show "----" on the display.
Residual current at zero <150mA.
