4.3 Preliminary Electronic Adjustment
After the foregoing preliminary checks and adjustments have been
made, turn the analyzer and recorder (if applicable) switches on (see Figure
4-1) and make the following checks and adjustments:
4.3.1 Meter-Recorder Alignment
If the application involves the use of an auxiliary recording and/or
indicating device, the following procedure should be used to check and
adjust the output circuit so that the meter and recorder are in close agree-
ment:
1. Set the analyzer span control so that the dial indicates the
number recorded in the Application Data sheet in the Appendix
under “Start-up Span Setting”.
2. Place the selector switch in the "LO" position.
3. Adjust the door-mounted zero control until the meter stabilizes
at a full scale indication.
4. Check the recorder reading. If the recorder’s input sensitivity
coincides with the analyzer’s output specification (see
Appendix: Specifications), the recorder should be at a balance
at its full scale marker.
