On the calibration screen M5/S1 the measuring range ‘3 (1)’ indicates the current ‘3’ and
the calibration measuring range ‘(1)’.
Note
The measuring range adjusts automatically to various calibration gas
concentrations while in calibration mode.
The test gas concentration, here ‘0.0’, is shown above the green arrow on the right hand-
side at the bottom of the screen. The green arrow is pointing at a measuring range of ‘-2.0
to +2.0 vol%’. The value of the actual gas concentration needs to be in this predefined
measuring range.
To adjust a calibration parameter, please tap on the edit button.
The M4/S2 screen opens with the channel-specific parameter ‘3 = Calibration’. Here you
can enter the parameters of your test gas and change the calibration parameters.

Please set the values to meet your calibration requirements. After adjusting the parame-
ters, please tap on the Calibration button M5 to confirm your entries.
Example of a manual calibration procedure

Example: in ‘Fig. 68 Manual calibration with span gas’ the test gas has a 20.91 vol% oxygen
concentration.
