Calibration

3.4.1

Cathodic Protection Current Adjustment

The current level required to prevent electrolytic degradation of the tank and chamber is between 25
and 30 milliamps as read on the instrument panel ammeter. This should be read and adjusted weekly
using the potentiometer knob directly below the ammeter. A zero reading at all potentiometer
settings indicates replacement of anodes is required. Refer to Service Section.

3.4.2

Relief Valve Calibration

The relief valve will need recalibration upon disassembly for cleaning following an over-pressure
condition. Refer to Bulletin 115.6020.
