21 Span calibration of
22 Setting setpoint values
5-12
Single calibration:
The display shows as many measuring ranges as was previously defined
via function 41. The adjacemt display therefore represents an example of
single calibration of four measuring ranges.
If measuring range 3, for example, is to be adjusted, the corresponding
softkey should be pressed.
The setpoint value and the current (ACTUAL) value for measuring range 3
appear on the screen.
Once the actual value has stabilized, the calibration procedure can be
started by pressing the fourth soft key. The actual value is now brought
into agreement with the setpoint value.
In the case of an inadvertently incorrect calibration (after using the wrong
calibration gas, for example), pressing the "ABORT" soft key will reload
the original calibration.
Total calibration:
Total calibration means that all measuring ranges are adjusted
simultaneously. The "leading" measuring range is defined under function
22 (see also menu 23 "General and single calibration"). It makes sense to
select the largest measuring range as the leading range.
The setpoint value and the current value for the "leading" measuring
range appear on the screen.
Once the actual value has stabilized, the calibration procedure can be
started by pressing the fourth soft key. The actual value is now brought
into agreement with the setpoint value.
In the case of an inadvertently incorrect calibration (after using the wrong
calibration gas, for example), pressing the "ABORT" soft key will reload
the original actual value.
The adjacent example to the left shows setpoint value input in the case of
total calibration. The fourth measuring range has been chosen as the
leading measuring range.
In the case of single calibration, it is not possible to specify the leading
measuring range.
