6.2. How to read the measurement value of the built-in temperature sensors.

MultiSync X461UN /X461HB /X431BT /P401 /P461 /P521 /P701 /S401 /S461 /S521 and MULTEOS M401 /M461

/M521 have three built-in temperature sensors.

The controller can monitor inside temperatures by using those sensors with external control.
