CAL-MENU
(MENU 3)
Important note:
Should you wish to change zero or span settings at any time, the original calibration made at time of
manufacture by GE will no longer apply. We therefore take no responsibility for any false or inaccurate
readings that occur after any changes to span have been made. If the temperature of the pressure sensor is
outside the range of 10 to 30 °C (50 to 86 °F) it will not be possible to perform the span operation.
Calibration Procedure:
If necessary then the span calibration should be made using a deadweight tester with an accuracy of 0.01% of
reading or better, and carried out in a temperature controlled environment at 20 ±2 ° (68 ±3.6 °F). C
To maintain the accuracy of the calibrator, do not increase the value of 'tol-ppm' above 50 ( see flow charts ).
For full calibration which includes Temperature Compensation between 0-50 °C (32-122 °F) the PC6-IDOS
should be sent back to GE .
