6 Manual CPM 374
The timer starts by passing the upper threshold (1000V in the example)
and determines the decay time by reaching the lower threshold (100V in the example). The pa-
rameters for the timer can be selected in the
Setup .
Important: Decay times
≤≤≤≤
0,1s are displayed as <0,1s
After the determination of the decay time (s), the offset voltage is measured after a defined time
period.
The measurement is finished after determining the offset voltage. All data required, e.g. to quali-
fy an air ionizer, can be read off the display. The offset voltage
UOFF and the associated time slice
are displayed in the upper line, the decay time is displayed in the bottom line as POS.DECAY or
NEG.DECAY or ii AUTO - Mode alternating every second:
The display remains until button «A» Continue is pressed.
OFF = XXXV T = XXXs
POS.DECAY = XX.Xs
