Description
Internal temperature
aM2!
aC2!
atttn<CR><LF>
with: ttt = number of seconds necessary for the in-
strument to make the measure available
(3 characters)
n = number of detected variables (1 character
for aM2!, 2 characters for aC2!)
Note: ttt = 000 means datum immediately available.
Request to execute the
measurement.
aD0!
a+t…t<CR><LF>
with t…t = internal temperature in the set unit of
measurement (default °C)
Example of response: 0+25.0
probe address = 0
internal temperature = 25.0 °C
Reads the measurement.
Signal internal level
aM3!
aC3!
atttn<CR><LF>
with: ttt = number of seconds necessary for the in-
strument to make the measure available
(3 characters)
n = number of detected variables (1 character
for aM3!, 2 characters for aC3!)
Note: ttt = 000 means datum immediately available.
Request to execute the
measurement.
aD0!
a+v…v<CR><LF>
with v…v = signal internal level in mV
Example of response: 0+3.294
probe address = 0
signal internal level = 3.294 mV
Reads the measurement.
In addition to the above-mentioned commands, the sensor also implements the corre-
sponding commands with CRC, that require to add a 3-character CRC code at the end of
the reply before <CR><LF>. The format of these commands is obtained from the pre-
vious by adding the letter C: aMC!, aMC1!, aMC2!, aMC3!, aCC!, aCC1!, aCC2!, aCC3!.
The sensor
does not
implement the type R (Continuous Measurements) commands.

Description
aXSCAL USER ON!
a> USER ENABLED!<CR><LF>
Enables the configuration
mode.
aXSCFD!
a> &<CR><LF>
Sets °C as temperature
unit of measurement.
aXSCFE!
a> &<CR><LF>
Sets °F as temperature
unit of measurement.
aXSCAL END!
a> LOCKED!<CR><LF>
Disables the configuration
mode.
The extended commands allow setting the temperature unit of measurement (if the
temperature sensor is present). To change the unit of measurement:
