Conversion of digital output value to analogue input signal:
Output value = Highbyte * 256 + Lowbyte;
Input signal Ud = (output value - 32768) / 32768 * 1050 °C;
Commands for configuration
The code of the command concerned is sent to the measuring amplifier for configuration.
Some commands expect parameters, e.g. the channel number “ch” and potentially other
bytes.
Note: To set the configuration, the data transfer should be interrupted by sending the
command “stop_transmission”.
After completing the configuration, the data transfer can be restarted again by executing the
command “start_transmission”.
Notes:
After each switch-on, the “normal mode” must be set in order to send commands (0x26
01 62 65 72 6C 69 6E).
