Appendix D
Voltage/Current Output Adjustment
Using This Appendix
This appendix describes adjustment procedures. The procedures in this appendix are intended for qualified service personnel.
Adjustment procedures are a part of calibration procedures. Calibration involves functional testing, performance testing, adjustment, and verification testing. These procedures are given in the HP E1418A
To maintain the output accuracy shown in Appendix A (see page 111), adjustment should be performed at 90 day intervals.
The HP E1418A Specifications (Appendix A) require that the operation temperature is within ±5°C of the calibration temperature. The module temperature is affected by both the ambient temperature and the cooling performance of the mainframe. Because VXI mainframes have significantly different cooling capabilities, the most accurate calibration is achieved when the Output Adjustment is performed with the module in the same environment and mainframe as it will be operating in.
Adjustment may be performed at more frequent intervals, if required. he module can be adjusted for use without changing the permanent calibration settings.
Adjustments are performed electronically. There are no mechanical adjustments in the module.
