Counters
To view the Counters menu:
1. From the Home screen, select 3: Service Tools .
2. Select 4: Maintenance .
3. Select 2: Counters / Timers .
4. Select 1: Counters .
The Counters / Timers menu displays the following counters:
• Sensor Wet Count – This counter increments each time the PV
(Output State) changes from Dry to Wet. This
counter can be reset or preset by setting a new
value
.
• Calibration Count – The 2160 is calibrated under reference
conditions at the factory. In special
circumstances, it may be re-calibrated in the
field and this increments the counter.
• Fault Count – This counter increments each time there is a
Fault condition (see “Sensor Status” on
page 2-18). This counter can be reset to zero.
