UHZ/R

• Operation

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.

Power on considerations

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.
