Intrinsic error (zero corrected)
Frequency operating range
Zero correction in DC
Beyond 200A DC, the display indicates «-OL» or «+OL» according to the polarity of the current
measured.
Beyond 200A peak (AC), the display indicates "OL".
Specific characteristics in MIN/MAX mode:
Extreme capture time: about 100 ms, displayed every 400 ms.
Specific characteristics in PEAK mode:
Intrinsic error: 10% L + 5 pt.
Capture time for the PEAK value: 1 to 4 ms according to the peak value.
Measuring current with a 1mV/A clamp
Refer to the description of measurement with the 714P.200 clamp, except there is no
indication of clamp presence.
Characteristics with a 1MV/A clamp
The following table indicates the tester's accuracy alone, while considering that the
clamp connected to the tester has a transfer ratio of 1 mV/A for direct reading. For
total measurement error, add to the tester's error that of the clamp used.
