General Description
Description Specifically for this Instrument
An event is recorded whenever at least one measured value has fallen short of the L-trig threshold
for at least one second, and subsequently at least one measured value has exceeded the H-trig
threshold for at least one second.
Parameters: L-TriG, H-TriG and rAtE DC
Parameters menu for harmonic analysis:
Included parameters: HArM.F (fundamental frequency), U.rAnGE (voltage measuring range) and
I.rAnGE (current measuring range).
Line frequency of the fundamental frequency (here: 16.7, 50, 60 or 400 Hz)
entered here in digits. The full measuring range corresponds to 60,000 digits.
The hysteresis setting allows for efficient use of memory space. During memory mode operation,
new measured data are only saved to a new memory block if they deviate from the previously
stored value by an amount which exceeds the selected hysteresis value.
