Differences and operations between zero-point fine tuning, offset adjustment, and full-scale fine tuning of transmitters
Thread Content
Zero-point fine tuning, offset adjustment, and full-scale fine tuning of transmitters are often confusing for beginners, especially zero-point fine tuning, which is sometimes used for offset adjustment. I have tried using zero-point fine tuning for offset adjustment, and it seems to work fine; no significant errors were observed. Is this approach also viable? A service engineer who works with transmitters in these tanks could explain, or someone with field experience might want to share their views.
As long as the zero-point adjustment can be moved to the desired position, it can be done using that adjustment; however, calibration with standard instruments is required after the movement.
The instructions state that it is for fine tuning, but will it actually cause out-of-tolerance conditions and large errors? Are there any people with prior experience or manufacturers who can provide information?
