Programming
Setting a parameter without writing it into the device EEPROM (Poll Mode)
This function is for test purposes only.
E#0.975<CR>
"E" is the parameter to be set
"#" is the command for "set parameter without writing it into the EEPROM"
"0.975" is the value for the parameter
<CR> <LF> (0D
It is possible to close with <CR> <LF> (0D
Device response format:
!E0.975<CR><LF>
"E" is the Parameter
"0.975" is the value for the parameter
<CR> <LF> (0D
After switching the power to "ON", the device is sending a notification:
#XI<CR><LF>
"#" is the parameter for "Notification"
"XI" is the value for the notification (here "XI"; unit switches to "ON")
<CR> <LF> (0D
Error message
*Syntax Error
"*" is the character for "Error"

7.3 Device Setup

7.3.1 Temperature Calculation

U=C
Physical Unit for the temperature value
E=0.950
Emissivity setting (Caution: according to the settings for the ES command).
XG=1.000
Setting for transmission
For the calculation of the temperature value, it is possible to set an offset (relative number to be added
to the temperature value), and a gain value.
DG=1.0000
Gain adjustment for the temperature signal
DO=0
Offset adjustment for the temperature signal
In case the ambient temperature is not requested by the internal head temperature, you must set the
ambient temperature values as follows:
A=250.0
Ambient temperature (example)
AC=1
Choice of compensation temperature value source

7.3.2 Selection of Emissivity and Alarm Outputs

The device allows three choices for the emissivity setting and two for the alarm output setting.
ES
Selection of the emissivity setting.
ES=I
Emissivity set by a constant number according to the "E" command
ES=E
Emissivity set by a voltage on FTC1 (analog input)
