5 | Operation Description G 1910-02 5 Operation 5.1 Commissioning 5.1.1 Explanation The product is switched on with the On/Off button. It may be necessary to configure the product after switching on. See Configuration [ 12]. A self-test is conducted after switching on. The following increasing CO2 values 1000, 2000, 4000 and 8000 are shown in the display. TEST is shown in the secondary display. If an alarm is active and is in one of these relevant areas, it is triggered.
G 1910-02 Operation | 5 3. By briefly pressing the Function key, you can scroll through the parameters. Select the parameter you would like to configure. 4. When you have selected the desired parameter, change the parameter to the desired value with the Up button and the Down button. 5. The changes are saved after running through the entire Configuration menu. STOR appears in the display.

However, it can be exited at any time by pressing the Function key for 2 seconds. The changes made up that point are also saved. If the product is switched off without saving the configuration, the last save value is reproduced on the next start-up of the product. 5.2.
G 1910-02 Operation | 5 NOTE The setpoint value of 400 ppm or depending on selection 0.040 % can be used for a simple adjustment in clean ambient air. Otherwise, use the expected value of the test gas according to the analysis certificate or display value of the reference device. Outcome of an action The changed value is saved and the Expanded settings menu is closed. STOR appears in the display.
6 | Measurement Basics G 1910-02 6 Measurement Basics 6.1 NDIR CO2 sensor 6.1.1 Explanation The sensors are based on non-dispersive infrared sensor technology, NDIR. This is the most widely used sensor technology for CO 2 measurement. The principle of the NDIR sensor is that an IR light source is focusses so that an optical beam is created, which passes through the existing gas, including CO2.
G 1910-02 Operation and maintenance | 7 7 Operation and maintenance 7.1 Operating and maintenance notices CAUTION Damage to the sensor A sensitive optical sensor is installed in the product. The sensor parameters can change due to impact or falling. This can result in incorrect measurements. – Protect the product from impact and falling! – The measurements must be checked after the product falls or is jarred.
7 | Operation and maintenance G 1910-02 – In order to protect the batteries, the charging process is not started when the charge cable is plugged in, if fully charged batteries are detected based on the voltage monitor. 7.2.
G 1910-02 7.3 Description Operation and maintenance | 7 CO2 adjustment In order to improve the accuracy, the carbon dioxide sensor can be adjusted. In order to conduct a CO2 adjustment, proceed as follows. 1-point adjustment Used for optimisation of the accuracy at the adjustment point. The best possible accuracy can be achieved even with elevated CO2 concentrations 2-point adjustment Used for optimisation of the accuracy for extreme requirements over a wide measuring range beginning from 0 ppm.
7 | Operation and maintenance G 1910-02 Instruction 1. If you would like to perform a adjustment with test gas, connect the extraction device to the product first. 2. Press the Function key for 4 seconds to start the adjustment. [ONF appears in the display first, then [AL. 3. 1-point, 2-point or basic sensor adjustment is started. This depends on what was adjusted in the Expanded settings menu. 1-point adjustment 1. [.SL appears in the display for 1-point adjustment. 2.
G 1910-02 Operation and maintenance | 7 5. If the display flashes briefly, an acoustic signal sounds and the bar display blinks, a stable correct value has been achieved. 6. You can change the value of the gradient compensation with the up key and down key. Otherwise, confirm the preadjusted value with the function key. Remove the extraction device. The 2-point adjustment is finished Basic sensor adjustment 1. KARD appears in the display for basic sensor adjustment. 2. Depending on the specification [.
