TESTO Gas detector, Инструкция по эксплуатации, Страница: 26 / 36

E.2 Connecting the sensor head
The sensor head and the gas detector are adjusted to each other in the factory. The
gas detector must be readjusted (Refer to Adjustung/Calibrating detector, P. 12) if the
sensor head is changed. The detector must be switched off when
connecting/changing the sensor head and sensor extension.
Plug sensor head onto connection socket and close screw cap.
Using sensor extension
1 Plug sensor extension onto the connection socket and close the screw cap.
2 Plug sensor head onto sensor extension and close the screw cap.
E.3 Switching on the detector
Keep pressed until there is a beep sound.
- All of the LEDs light up, all display segments light up briefly.
- The warm-up phase (duration: 40s) begins:
HEAt and CH4 (standard gas type when
detector is started) are displayed alternately. The bar diagram shows how the warm-
up phase is progressing by adding in segments. The “Operate” LED flashes, the
other LEDs are gradually deleted.
Changing the gas type
Keep pressed until there is a beep sound.
- The gas type is changed (setting sequence: CH4 , C3H8 , H2 )
- Once the warm-up phase is complete, the detector changes to the display “Gas
concentration”: The current gas concentration, unit and are displayed. The audible
concentration display is heard.
