I am using the LabJack T4. I notice that my AIN0 was not reading the voltage from the DAC0 output.

When I was looking thtough Kipling I notice that there was a hardware issue detected and the tempoerature reading is 194 deg. Celcius I saw information about how to set a to factory reset and to check the device. The information I found was for the T7.

Is there a way to reset the T4 and Check the device, or is there any recomended steps that I can take?

Thank you .

Hmmm, failure or even damage

Hmmm, failure or even damage is very unusual, but a problem with just AIN0 would be even more unusual. See if all analog inputs are having a problem.

A few things to do:

-Remove all connections from the T4 except for USB. This includes ANY and ALL connections to screw terminals or DB15/DB37 ports.
-Install a small jumper wire securely from FIO6 to SPC to cause a factory reset on next boot.
-Disconnect & re-connect USB to power-cycle the device.
-Remove the FIO6 - SPC jumper.
-Disconnect & re-connect USB to power-cycle the device.
