SYSTEM MAINTENANCE 

 

8.1 

Preventive Maintenance 

 
The PCS Instrument requires minimal operator maintenance. To maintain 
the PCS in top performance condition, it is recommended to keep the 
instrument dust free, periodically clean the exterior, and have it inspected 
annually by the manufacturer. The operator, depending upon the condition 
of the working environment, should determine the frequency of 
maintenance. 

8.1.1

 

Cleaning the Cabinet

 

To clean the cabinet, use only a clean water-dampened cloth. If the 
bores of the vial block need cleaning, use damp cotton swabs. 

8.2 

Instrument Calibration 

 
Follow the procedure described in Section 5.0, “Instrument CAL A and 
Calibration” 

8.3 

Removal of Rear Access Cover 

 
The Rear Access Cover can be removed from the PCS Instrument. 
Removing the cover permits access to the user replaceable PROM card. 

 

CAUTION!  

Disconnect all external cabling. Prior to removal of cover components the power must be 

turned off and the external Power Supply unplugged from the Instrument. 

 

8.3.1 

Locate and unfasten the two (2) quarter-turn fasteners on the Rear 
Access Cover. To unfasten the quarter-turn fasteners, use a 
screwdriver, insert the blade in the slot and rotate 1/4 turn counter 
clockwise. The fastener will pop out 1/4 inch, indicating an 
unfastened condition.  

 

IMPORTANT:  

The Vial Block on the Rear Access Cover has a cable that is attached via a connector to the 

main circuit board. If the connector becomes disconnected, reconnect prior to replacing the 
Rear Access Cover onto the Instrument. 

8.3.2

  Remove the Rear Access Cover and place directly behind PCS 

Instrument.

  

8.3.3 

To replace the Rear Access Cover onto the Instrument, align the 
top tabs with the cabinet. Push in the quarter-turn fasteners and 
turn them clockwise until the fasteners are inserted and secure.
