Specifications Of Frequency Measurements - Chauvin Arnoux F 1N Mode D'emploi

Specifications in SMOOTH and RECORD SMOOTH modes
SMOOTH mode improves signal stability.
Resolution and stability: 1 count.
Filtering time: 3 seconds.

SPECIFICATIONS OF FREQUENCY MEASUREMENTS

On manual ranges:
On the 40.00 A range, the current must be above 4.5 A and on the 400.0 A range, it must be
above 45 A ± 25 % in the 45 Hz - 1 kHz band.
Below 0.5 Hz or if the detection level is too low, the meter reads 0.0 Hz.
Resolution: 1 count.
Stability: 2 counts.
Response time: 500 ms for frequencies above 20 Hz. Up to 4 s for frequencies below
20 Hz.

MEASUREMENT ERROR
On auto range:
The minimum switching threshold is above 300 mA. Between 1800 Hz and 2000 Hz, the
measurement is progressively subject to an instability of from 2 counts to 13 counts.
