TAI aligns the system's electronics. However, you may
need to touch up the circuitry, using the following procedure.
Oscilloscope (dual trace is preferred, but not required) To observe
oscilloscope test points switch the vertical input selector of the scope to DC.
Measure +15 volt ±1 volt DC and -15 volt ±1 volt DC on the differential
power supply PC board in the control unit. Refer to the power supply schematic
in the back of the manual to identify the power supply test points, or section 3.6
in this chapter.
3.5.3 Setup of the Signal Processing Front-End
Fill the sample cell with air or a stable fluid, such that the photo
energy that strikes the detector is constant. A stable fluid is distilled or tap
water. This step may be omitted when the system is stable in its present
state.
Check the UV source.
Check the solenoid valves.
