2. LF pulse scaler TERZ 94 / 94-S
The frequency of the LF pulses is set by a pulse scaler (A07). There are the
following setting options: 0.01; 0.1; 1; 10; 100.
Other values can not be programmed, it is only possible to scroll in the list of
these values (‘t’ key vesp. ‘_’ key).
This pulse scaler has only effect on the frequency of the LF pulses not on the
display. The number of displayed digits after decimal point or a multiplier are
programmed as an operating mode (A08)
