Zero calibration (function 20)

Figure 6-3
In order to calibrate the zero point, the device must be in "Measuring" operating state. If this
is not the case, calibration is not possible. The display will show the message
not measuring"
The zero calibration is performed simultaneously for all measuring ranges, even when the
span of the measuring ranges is calibrated individually.
After call of function 20, the internal zero gas valve is opened.
Only initiate calibration when the measured value (actual value) has stabilized after feeding
the zero gas. Otherwise, the calibration may be imprecise.
If there is a lot of noise, increase the time constant before calibrating (function 50).
