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:
- 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 in AC and AC+DC):

Accuracy: add 1% R to the values of the table above.

Capture of the extreme: approximately 100ms.
Specific characteristics in PEAK mode in current
(from 10Hz to 1kHz in AC and AC+DC):

Accuracy: add 1.5% R to the values in the tables above.

PEAK capture time: 1ms min. to 1.5ms max.
