7.4.3

Operating mode: Verification (special mode)

This operating mode can be used for device control. Manual - - similar to the
operational calibration in the previous section - - or automatic execution are
possible, see 8.4.1 Setting or changing automatic measurements
➪
A test gas of known composition is analysed for this purpose and the result is com-
pared with the data of the manufacturer's analysis certificate of this gas.
As a rule, the process gas input for this operating mode must be con-
nected to the test gas in the gas line (calibration gas input also
possible). During this special mode, the last gas quality values of the ana-
lysis mode are output via measured value outputs. The analysis data of
the gas must be stored exactly, a deviation will result in invalid values.
The comparison can be carried out on the actual displays. Use the superimposition
keys to navigate to the Verification display and select "Deltas" in the topmost line.
The differences between the measurement results and the data saved on the man-
ufacturer's analysis certificate are visible in this display (only if a measurement has
been completed, otherwise "?" will be displayed).
The data for the test gas can be viewed by selecting "References" on the Veri-
fication display. You will also see the HsV and Rho values calculated from the gas
composition and the displayed standard.
If you are logged in and have the appropriate rights, you can also enter and edit the
manufacturer's analysis certificate.
The calculated results can also be saved in an archive, for example "Test gas". This
archive must first be created in enSuite. See section
meterization (p. 229).
Prerequisite(s)
