Old
Field type: Display
These fields display the data from the
last calibration procedure, if the input has already been
calibrated.
• Measurement value and internal signal UA for zero gas (CAL-ZERO)
• Measurement value and internal signal UA for test gas (CAL-SPAN)
New
Field type: Display
These fields display the data for the
current calibration process.
In the case of semi-automatic calibration (not available at present), the system automatically
fills the signal values (mV) captured for zero gas (CAL-ZERO) and span gas (CAL-SPAN) in
the fields “value” and “internal signal UA”, as soon as the calibration phase has finished. In
manual calibration, the current measurement value is captured and placed in the corresponding
field when the “Store” button is pressed, depending on the calibration phase.
Sig.
Field type: Display
The current measured value and the current internal signal UA are displayed and updated every
second.
Ux
Field type: Display
Display of the current difference signal Ux at passive sensors, if the measure point has already
been calibrated. Otherwise no value is displayed (which means: no preliminary calibration done)
or ***** (active sensor) is shown.
At preliminary calibration the difference signal Ux for zero gas is set to 0 mV. At all following
calibrations the current difference signal is always based on the defined value.
