(This command is READ ONLY.)
Note: When viewing the Present Operating Temperature, allow at least 20 min-
utes after startup for the scanner’s inside and outside temperatures to stabilize.
Definition: Close estimation of external temperature.
A thermal sensor on the main PCB measures the internal temperature
of the scanner. From this a case-differential constant is subtracted to
yield an estimated external temperature.
Usage: Indicates temperature of the environment immediately outside of the
scanner. Useful for setting Over Temperature Threshold and Under
Temperature Threshold.
Serial Cmd: Send: <K%?>
Returns <K% degrees Celsius>.
