Accuracy (error of reading) of input from non-contact thermo probe (channel D):
The error of reading of the input from a non-contact thermo probe that can be connected to the TM20 (i.e., Model
900 03) is
±
1
°
C excluding the error of the probe itself. (For the error of the non-contact thermo probe, see the
respective specifications.)

Battery life
(when not using the backlight of the LCD)
When using collector function:
Approx. 2 days (under continuous 24-hour operation) (when the RS-232-C
cable is not connected.)
