Triggering threshold
NB : Below 0.5 Hz display of 0.00 Hz
If the level of detection is insufficient, display of indeterminate value (- - - -).
Response time of the digital display :
- Normal mode
- SMOOTH mode
Special case of measurement of harmonic rates
On HARMONIC function, the clamp can also indicate the frequency of the harmonic components, if the fundamental
frequency is between 40 Hz and 70 Hz. Outside of this limit the clamp displays an indeterminate value (- - - -).
