The data format for Detection data output contains of ten ASCII characters. Nine
characters show the value in engineering format (See “Engineering format” on
page 17), and one character shows linefeed (LF).
The print time is 50Hz continuous streaming data.
Note:
Data rate is 25Hz when Sensistor ISH2000 is running in
Service Display Mode
.
RS232 serial communication
The most commonly used Sensistor ISH2000 functions can be started/configured
over the RS232 interface.

K = Calibration request
Starts calibration if the Sensistor ISH2000 has an active probe driver installed.
Sensistor ISH2000 answers with a "K" if an active driver containing a calibration
routine was found and "F" if the calibration APC sequence not found. Calibration
doesn’t start if Purge level is reached.
