Any way to turn off Back Light?

On my HUM device, is there any way to turn off the back light on the unit? It generates a lot of heat and I think it is affecting the temperature reading.

Yes, you can disable the backlight by setting one of the options there on the user interface. Please download the T3000 software from the product pages and connect to the device. Update the firmware while you’re at it (T3000 → help → check for updates). There were some features added not long ago to completely disable the LCD display, some folks were asking for it so that’s one new option.
