/ SMOOTH KEY

The SMOOTH secondary function activates / deactivates an insulation measurement digital fi lter. It
affects only the display (which is smoothed), not the measurements.
This function is useful if the insulation values displayed are very unstable.
The fi lter is calculated as follows:
RSMOOTH = RSMOOTH + (R – RSMOOTH) / N
Since N is set to 20, the time constant of this fi lter is approximately 20 seconds.
