10.1.6.1 Electric Test (ET) Procedure
1. Any time the gain of the PMT buffer amplifier circuit (R19) is changed (refer component
location label inside of the Preamp cover), that will change the ET reading. Since the gain
was adjusted in the above procedure, do the following to re-adjust the ET signal.
2. To re-adjust ET press SETUP-MORE-DIAG, then scroll to ELEC TEST and press ENTR.
3. Scroll the TEST functions until PMT is displayed.
4. Adjust R27 until 2000 mV ± 50 is displayed.
5. Press EXIT to return to SAMPLE mode.
10.1.6.2 Optic Test (OT) Procedure
1. Any time the PMT buffer amplifier circuit (R19) gain and/or the PMT high voltage setting is
changed, the OT reading will also change. The PMT cal procedure changed both of these
values.
2. To re-adjust OT press SETUP-MORE-DIAG, then scroll to OPTIC TEST and press ENTR.
3. Scroll the TEST functions until PMT is displayed.
4. Adjust R25 until 200 mV ± 20 is displayed.
5. Press EXIT to return to SAMPLE mode.
