4. Replace any pump malfanctioning parts as necessary.
5. Replace any tubing which cannot be properly cleaned.

7.0 SERVICE PROCEDURES AND
ADJUSTMENTS
The system’s electronics are factory aligned. However, when the need
arises to touch up the circuitry, the following procedure is suggested.
1- Oscilloscope (dual trace preferred but not required).
To observe oscilloscope test points (see Detector Module Assembly Dwg.)
switch the vertical input selector of the scope to DC.
2-DVM (Digital Voltmeter)
The PC Board Extender is used whenever trimpot adjustments must be
made. Because all PC Board connectors are keyed to avoid wrong positioning
in the connectors, the key must be removed and later after testing, reinstalled
with long nose pliers. Turn power off during this operation.
