When zero or span gas is flowing, the measured value can be saved by pressing F1. If the
screen is left by pressing the buttons ”Main” or ”Back”, the measured value is not saved.
Solenoids are closed by pressing F2.

Display Deviations – from Calibration menu F3
Figure 7-13 Display deviations
After every calibration, the deviations are calculated for zero and for span gas.
F1 Zero gas deviations
F2 Span gas deviations
F3 Deviations of zero gas during verifying
F4 Deviations of span gas during verifying
F1 and F2 deviations are displayed in percent.
Figure 7-14 Zero gas deviations
Figure 7-15 Span gas deviations
During calibration, there is verification for zero and span gas. With option F3 and F4, you
can view the deviations during the verification time. Absolute deviation is the absolute
average difference from the saved value in ppm. Relative deviation is the absolute
average difference in percent, related to the range limit.
7.4.4.
Absolute Zero Gas Deviation
Absolute zero gas deviation is zero gas content calculated by the factory polynomial
related to the range limit of the calibrated range.
7.4.5.
Relative Zero Gas Deviation
Relative zero gas deviation is the actual deviation minus the deviation of the previous
calibration related to the range limit of the calibrated range.
