Unistream Touch Screen Calibration Always Failing

[Martin Sirovy]

Dear Support team,

I have the Unistream US5-B10-B1 OPLC. The factory default touch screen calibration is bad, hence I used the Touch Screen Calibration command from the Uniapps menu. It usually worked well, however on this peace of hardware after touching all the 5 points, it writes "Calibration Failed" and recommends to do it again or restart...I have tried it sereral times with the same result. Any recommendations?

Thank  you,

Best regards,

Martin Sirovy.

This forum does not contain a "Support Team". It is a user forum staffed by volunteer users, though a few Unitronics employees make an appearance from time-to-time. Unitronics support can be reached at support@unitronics.com. For a hardware issue under warranty you might also consider contacting your distributor for return or replacement.

Regarding your question, I haven't encountered that particular issue before but perhaps someone here has. Good luck.

Thank you Flex727, I have sent the message on the support email as well, I will report here the conclusion. Martin.

The conclusion from Unitronics support - probably HW issue.  However I tried it for the last time today before sending back and the calibration past with no problem. The only difference I see I did not have so dry fingers today as last time.
