Calibrating the Detector
ChromQuest contains the following built-in calibration procedures for the Surveyor RI Plus
Detector: Validation Procedure, Span Adjustment, Recorder Output Adjustment, Integrator
Output Adjustment, and Intensity Adjustment.
Perform the Validation Procedure, which validates the accuracy of the detector, on a regularly
scheduled basis. For information on performing this procedure, see the
Surveyor Plus Getting
Started with ChromQuest Guide .
The Span Adjustment and Intensity Adjustment procedures should be performed by a
Thermo Fisher Scientific Service Engineer after the tungsten lamp is replaced.
Use the Recorder Output Adjustment and Integrator Output Adjustment procedures to
adjust the gain if you have connected a chart recorder or an integrator to the back panel of the
detector.
This section contains the following topics:
• Recorder Output Adjustment Procedure
• Integrator Output Adjustment Procedure
Recorder Output Adjustment Procedure
Use the recorder output adjustment procedure to calibrate and adjust the recorder gain. You
must have high precision multimeter to check the output.
Y To adjust the recorder gain
1. Connect the pin connector adapter to pins 9 and 10, located on the back of the detector.
See Figure 19 .
