Digitron APM140 Differential Manometer - Out of range issue

[Hitech]

Hi, I wonder if anyone here can help me in resolving this issue.

The meter I have stops at 19mbar with 'out of range' message and I cannot use it for other pressure checks.

The instruction manual is not helpful. I contacted Digitron but they are not replying. The meter range is upto 130mb and I guess I pressed some button and it locked to 19mb.

Any help will be greatly appreciated. Thank you

It sounds like your meter might be in a locked mode or has a calibration issue perhaps? Try resetting it to factory settings - you can look for a reset button or option in the menu. If that doesn't work, check if there's a specific combination of buttons to unlock or recalibrate it.

You are putting the tube on the right inlet eg the plus one ?

Thank you for your reply The meter has range from 0 to 130 mbar. I accidently locked it to 'out of range' mode and the instruction manual has no information how to take it out from this mode.

Thank you for your reply. Yes the tube is connected to the right side positive port.
