MAINTENANCE AND RECALIBRATION
General: P, PC, PCR and PCD-Series Pressure Gauges and Controllers require
minimal maintenance. They have no moving parts. The single most important thing
that affects the life and accuracy of these devices is the quality of the gas being
measured. The instruments are designed to measure CLEAN, DRY, NON-CORROSIVE
gases. If your application requires an aggressive or corrosive gas, please consider
Alicat’s PS, PCS, PCRS and PCDS Series instruments (see page 60).
Recalibration: The recommended period for recalibration is once every year. A
label located on the back of the controller lists the most recent calibration date.
The controller should be returned to the factory for recalibration within one
year from the listed date. Before calling to schedule a recalibration, please note
the serial number on the back of the meter. The Serial Number, Model Number,
and Date of Manufacture are also available on the Model Info display (page 20).
Cleaning: P, PC, PCR and PCD-Series Pressure Gauges and Controllers require
no periodic cleaning. If necessary, the outside of the controller can be cleaned
with a soft dry cloth. Avoid excess moisture or solvents.
