EVEntS Submenu for events
recording parameters
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

HArM Submenu for
harmonics parameters
Parameters menu for harmonic analysis:
Included parameters: HArM.F (fundamental frequency), U.rAnGE (voltage measuring range) and
I.rAnGE (current measuring range).

HArM.F Fundamental frequency See HArM
Line frequency of the fundamental frequency (here: 16.7, 50, 60 or 400 Hz)
HiVolt LiMit Upper trigger threshold The threshold value for overvoltage (HiVolt LiMit) while monitoring the TRMS voltage value can be
entered here in digits. The full measuring range corresponds to 60,000 digits.

HYSt Hysteresis 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.
