2. Handling
The instrument PFM Flex 4 is robust
and easy to handle but should not
be exposed to careless usage.
Avoid exposing the instrument to
temperatures below zero degrees C
if there is water in the Sensor.
To empty the Sensor just open the
Sensor valve (by-pass position) and
shake the Sensor.
If the instrument is not being used for
a period, we recommend overhaul
charging of Sensor and Hand
Terminal.
