The adjacent display appears.
In the case of analyzers with an internal sample gas pump, se‐
lecting this function switches from the sample gas inlet (inlet 1)
to the zero gas inlet (inlet 3).
Calibrate the zero point as follows:
• Connect zero gas to the analyzer and observe the display.
• Wait until the displayed value has stabilized.
• Commence with correction of the zero point by pressing the
<ENTER> key.
• Exit the calibration by pressing the <ESC> key.
The message "Tolerance not o.k." appears if an error occurs during the calibration.

Calibrate the sensitivity as follows:
1. Position the cursor on the 3rd line of the display
(Start cal. MR 1+2).
2. Press the <ENTER> key.
The adjacent display appears. Now carry out the following steps
for the sensitivity calibration:
1. Connect the sample gas inlet to the calibration gas.
2. Inject calibration gas to the sensor with a 󹪞ow rate of
1.2 ... 2.0 l/min.
3. Wait until the measured value has stabilized.
4. Then press the <ENTER> key.
5. Exit the calibration by pressing the <ESC> key.
The message "Tolerance not o.k." appears if an error occurs during the calibration.
