Resolution 0.01A
Note (1) In DC, the display indicates "+OL" above +3000A and "+-OL" above -
3000A in REL mode. The "-" and "+" signs are managed (polarity).
In AC and AC+DC, 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:
- In DC: depends on the remanence. This can be corrected by the
"DC zero" function of the HOLD button
- In AC: <150mA
Specific Specifications in MAX/MIN mode
(from 10Hz to 1kHz, and from 0.30A in AC):

Accuracy: add ± (1.5% L+0.5A) to the values in the tables above.

PEAK capture time: 1ms min. to 1.5ms max.
Specific characteristics in PEAK mode in current
