The display indicates "+OL" above 1500A.
Note (2)
The residual current at zero depends on the remanence. It can be
corrected by the "DC zero" function of the HOLD button.

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.
