Unable to calibrate voltage

[Charlie]

Hi Guys
I am having a problem on a DC150 with firmware 1.5.8 board rev F

The voltage reading is about 0.3v below the actual input voltage and so I have been trying to calibrate the netonix unit.

When the unit reads 13.5v and says "not calibrated" I click the calibrate button and input 13.8
The unit appears to reload various the status meters and then shows the same incorrect voltage as before.
The status does change to Calibrated though. Until I refresh the page - then it says Not Calibrated.

I have also tried calibrating via the calibrate ssh command and also having no luck, confirming browser zoom set to 100% and trying both firefox and opera browsers.

Does anyone know what could be preventing this from working?

Also reporting the same problem with the voltage calibration not being successful on two different WS-8-150-DC. Have tried both 1.5.6 and 1.5.9RC1, and tried Firefox, Chrome and Safari. Have also tried http and https. All of the power status bars turn red for about 1 second after the new voltage is entered and applied, the voltage calibration button reads Calibrated until a browser refresh, and then Not Calibrated and the unchanged voltage is reported. The Status graph is cleared by doing this, but the old voltage is reported. I was trying to go from 26.1V to 26.5V, which has been verified by three voltage meters.

The log reports:

Update. I was able to successfully calibrate using the console....
