Moisture Sensor
5 Moisture Sensor
The LPA² version fitted with the optional moisture sensor module
allows both measurement of % saturation of water in oil (Relative
Humidity) and temperature. These are displayed as RH % and °C
on the main/test progress screen and on the printed results.
Temperature measurement provides a reference temperature for the
RH reading.
Due to the temperature gradient existing between the system
tapping point and the RH/temperature module, the tempera-
ture reading can be 5°C to 10°C less than the actual system
temperature, depending on operating conditions.
The LPA² can be configured to do a test with or without the moisture
sensor selected. If the moisture sensor has been selected, the flush
valve will open automatically for a period of 3 minutes before the
particle count test commences. This is to allow the moisture sensor
to stabilise and give an accurate reading.
To switch the moisture sensor
ON
or
OFF
, select the Test Option
Screen, as described on page 14. The Test Options Screen will be
displayed.
