General
The UHZ/R is an auxiliary powered, alarm module for frequency based
signals. It has two alarm channels and a digital display built in. The
maximum input frequency is 10 kHz (with overrange to 16 kHz).
Cleaning
The case can be wiped with a damp cloth. De-energise the unit before
cleaning.
Poweronconsiderations
When the unit starts it assumes an input frequency of zero, so the
alarms and display are set accordingly. Their state is not changed until
the first measurement cycle has been completed.
