you CAN NOT CORRECT THE CALIBRATION, YOU NEED TO DO CALIBRATION TO VERIFY THE ACCURACY OF THE PRESSURE CHART RECORDER

When I did this video it was purely to show how to adjust . If you listen to my commentary I say that I corrected the recorder by knowing exactly where the linkage position should be . however what you say is correct the only way to correct is to do a full calibration. It is however common place in industrial applications for users to adjust the zero to compensate for transportation etc this is a questionable practise as it assumes all adjustments apart from zero have not changed . After 40 years and having been trained by the best of the best I would like to think I know what I am talking about .

@@heiengine normal practice, is to check zero , 50% and 100% of full scale or full span using the deadweight tester. If the pointer on the chart is out, then adjust the linkage of the pointer.

@@heiengine yes, i respect your expertise in calibration works. How many times do we need to repeat (for conducting repeatability test) and do the full range calibration of the scale of the chart recorder.
