4. Operation of the System
Zero gas (concentration)
Element type: Decimal number
Enter the zero gas concentration in this field. This should be the same as the measurement
range zero, i.e. normally zero. The field defaults to the value of the last calibration, if the input
has already been calibrated.
Test gas (concentration)
Field type: Decimal number
Enter the test gas concentration in this field. The field defaults to the value of the last calibration,
if the input has already been calibrated.
Units
Field type: Display
The field beside the concentration shows the units of the selected input.
Zero gas (type)
Field type: Display
The field shows the type of the zero gas (e.g. air, nitrogen) of the input selected.
Test gas (type)
Field type: Selection
The field contains a list of test gases that can be used to calibrate inputs. It defaults to the
reference gas for the selected input.
Start
Field type: Button
Pressing this button starts the calibration process and automatically inhibits the output from
that channel. After the button is pressed, the parameters are immediately checked to see if
they are valid. If the parameters are valid and the selected input is not in alarm mode or
inhibited, the calibration process begins and the “Calibration end” submenu appears.
Cancel
Field type: Button
Pressing this button cancels the parameter changes and closes the menu.
