96 Equipment Connections
Notice If a calibration is started within the first 20 min after power on a warning is
issued. The ERROR output signal will go to LOW and the READY signal
will go to HIGH (not ready). In this case, a calibration will not be started until
the CLEAR ERROR input signal is set to HIGH (calibration will be started
afterwards). Alternatively the calibration may be aborted by setting the
CALIBRATION ABORT input signal to HIGH.
When the calibration process has been started the Protec P3000 sets the
CALIBRA-
TION STABLE output signal to LOW after the signal had enough time to stabilize. The
sniffer probe tip then needs to be moved away from the test leak and the
CALIBRATION
input needs to be set back to LOW afterwards.
The
CALIBRATION STABLE output signal stays LOW and is set back to HIGH when the
background signal also had enough time to stabilize. At this time the calibration will
be completed, the results of the calibration process will be shown on the main display
for 3 seconds. After that the main display will go back into measurement mode. The
READY output signal will go back to LOW at that time.
If
ABORT is sent during a calibration before the last edge of the CALIBRATION signal,
the calibration process will be aborted.
In case of an error during calibration, the
READY output signal will remain HIGH until
the error is erased by the
CLEAR ERROR input signal.
6.2 RS232 interface
The RS232 interface can be used for external control of the Protec P3000 but also
for simple export of data describing testing results.
For how to set-up the RS232 interface please refer to Section 4.5.
For a detailed description of the RS232 interface and its commands please refer to
the “Protec P3000 Interface Description” (kins26e1)
