4. Maintenance
A. Power Requirements
The PCL1000 operates on 4 AA alkaline batteries. To replace the alkaline bat-
teries, remove the two (2) screws on the rear battery door and lift the battery
cover.
B. Calibration
The PCL1000 should hold its rated specifications for a minimum of one
year. Given this, annual re-calibration is required for best performance.
