06 MAINTENANCE AND USER ADJUSTMENT
PFM-711B Field Meter
The PFM-711B is factory calibrated and other than battery replacement and external cleaning,
general user maintenance is not required. The case has been sealed and BREAKING THE SEALS WILL
VOID THE WARRANTY.
If for any reason you believe the meter is not working correctly, contact Prostat or an Authorized
Calibration Lab for assistance.
Clean the meter case with a dry, soft, non-scratching cloth
DO NOT USE solution to wet the case
Carefully wipe the case and display until dust and dirt are removed
CAUTION
In rare cases cleaning the PFM-711B case with a slightly dampened cloth may be required. Should
this be required, use a very weak solution of liquid soap and water. The cloth should be barely
damp. DO NOT allow cleaning solution to enter the unit through its openings.
Should the unit become damaged through the use of cleaning solutions, the warranty will be
voided.
