2.2 SOPAS ET (PC program)
SOPAS ET can be used to set the GM32 parameters and provides access to the GM32 log-
book.
SOPAS ET runs on an external PC connected via the Ethernet interface to which the GM32
is connected, see “Laying the electrical connection lines”, page 19.
2.3 Reference cycle
Internal drifts correction in an adjustable interval (standard: 1 hour, setting: SOPAS ET) or
per command (with SOPAS ET).
Measured value output during the reference cycle: Last valid measured value.
2.4 Check cycle
The check cycle comprises the reference cycle, followed by the check and output of the zero
and check point (70% of FS).
It is performed in an adjustable interval (with SOPAS ET), via a command (with SOPAS ET) or
via an external signal (option).
With the check cycle, the device is capable of checking the zero point and a span point for
each component without feeding test gases. The check cycle meets the requirements of
EN14181 and makes drift monitoring with test gases according to QAL3 unnecessary.
● Zero point
An internal zero point reflector is swiveled in time-controlled in adjustable intervals. The
emitted light is reflected back in the sender/receiver unit to the detector, the zero spec-
trum is evaluated with the calibration function and thus the zero points of all ducts mea-
sured and output.
If the deviation from zero is > ±2% of the FS, Maintenance request is signaled.
