3.5Service Procedures and Adjustments

3.5.1 Electronics

TAI aligns the system’s electronics. However, you may need to touch up the circuitry, using the following procedure.

Equipment Required:

Oscilloscope (dual trace is preferred, but not required) To observe oscilloscope test points switch the vertical input selector of the scope to DC.

Switch to AC to observe the demodulator switch signals.

DVM (Digital Voltmeter)

3.5.2 Power Supply Test Points

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.

3.5.3Setup of the Signal Processing Front-End Amplifiers

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.
