Unexpected results
obtained from sample
Check that the minimess hose has been fully connected at
both the system and the PML² ends.
Confirm that there is a free flow of fluid to the PML², by
operating the flush valve and observing fluid passing to
waste.
High water/ aeration levels.
Test stops after
sampling has
commenced
If low pressure status is shown on the Remote Device dia-
logue, check that the fluid supply to the PML² is connected
and pressurised.
Remote Device dialogue
not responding to
buttons being pressed
Check that correct COM port has been selected in the Re-
mote Device dialogue.
Disconnect power supply to PML² and then reconnect it.
If excessive system contamination is suspected, flush out the Analyser using a
Bottle Sampling Unit in conjunction with a suitable solvent. Refer to the website
for more information on flushing fluids. www.mpfiltri.co.uk
DO NOT USE ACETONE
Low Pressure
The PML² must always be connected to an inlet oil supply when carrying out a test, as
operating the unit ’dry’ could cause internal damage to the pump etc. To prevent this
happening a switch is incorporated inside the PML² which detects low pressure and
stops the test. If this occurs the status on the Remote Device dialogue will be shown
as ’Low Pressure’, and ’L’ will also be displayed on the Remote Display is being used
with the unit.
