Device and Measuring Parameters
PEAK LiMit – Maximum Peak Value for Measuring Voltage
The momentary value of the applied signal is measured 1200
times per second and compared with the limit selected here (inde-
pendent of polarity). If this value exceeds the selected limit, a +/–
PEAK event is recorded for the respective half-cycle, and the peak
voltage value of the half-cycle is then displayed.
The limit is specified in digits: Due to the fact that this value is the
peak voltage value, a value which is greater than the measuring
range span (which corresponds to 60,000 digits) can be selected.

Note
Due to the fact that it's possible to record one +PEAK and
one –PEAK event for each half-cycle, as many as 200 or 240
events can occur per second if the limit is set too low!

Steep Sloped Voltage Transients
A trigger threshold can be specified here as an absolute value for
steep sloped voltage transients which are superimposed to mains
voltage. This is a polarity-independent entry relative to the momen-
tary value. Regardless of the selected measuring range, acquisition
always takes place within a range of 200 to 1000 V.
