Mode Sensor Transition - thyracont VSM72 Betriebsanleitung

4.6
By default the VSM72 performs a continuous transition between Pirani and cold
cathode range whereupon an assimilation of the sensor signals is carried out.
In order to adapt the performance of the transducer to the requirements of the
vacuum process you can configure the parameter "mode sensor transition"
according to the following:

1.0 x10 mbar
continuous transition in the range 1.0 – 2.0x10
Address Code
3 Bytes, decimal; address space RS485: 001 – 999
"W" for reading, "w" for writing the parameter
6 Bytes; "000001" transition, "000000" direct switch-over
1 Byte, checksum, defined as sum over all Bytes of the fields
