Step
Action: Manual operational calibration
7.
If you want to cancel the process prematurely, you can end the calibration after point 4
by selecting “
Cancel
”. The
measurement device will then interrupt the calibration
process. The system will be flushed with process gas and the normal operating state
“
Analysis
” will be performed again. This is shown on the status line.
You will be notified of the cancellation again
by the “
Confirm
” button, clicking on which
will take you straight to step 8.
8.
After the display time has elapsed, the
calibration will be finished and
analysis mode with measurements
will be continued automatically
.
Click on the displayed “
Main display
”
button to view current analysis values
from normal operation again.
Figure 7.56: Manual calibration ended
The last valid gas property values are held throughout the calibration time using
measurement outputs.
The parameters from the last successful calibration remain in use until a new
successful calibration has taken place.
Errors will be displayed on the device and documented in the “Error List”.
If necessary, contact Honeywell to arrange the appropriate action, for example a
base calibration.
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
. A test gas of known composition is analysed for this purpose and the
result is compared 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 connected to the
test gas in the gas line (calibration gas input also possible).
During this special mode, the last gas quality values of the analysis mode are output
via measured value outputs.
The analysis data of the gas must be stored exactly, a deviation will result in invalid
values.
