computer through the RS 232 interface
RS 232 interface
The RS 232 interface makes it possible to control the leak detector with a PC
compatible computer: it is installed on all leak detectors.

Common used functions
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 calibra-
tion routine was found and "F" if the calibration APC sequence not found. Cal-
ibration doesn’t start if Purge level is reached.
M = Measure Request
The active test cycle defined by the APC driver starts. “M” is returned if the
selected driver supports active test. “F” (failed) is returned otherwise.
N = Print Request
Returns current analysis value.
