Operation

7.1 Before first use

• Fully charge the battery before the first use. The charging socket is located on the right side above the sensor arm bracket.
• Switch on the meter using the “On / Off” key and leave the device switched on for about one hour for the sensor to acclimatise. Deactivate the automatic power-off function with the APO key.
• If you do not use the device for more than two months, repeat this procedure.

7.2 Before use

• Check the meter for mechanical damage.
• Only switch on the unit in an environment unpolluted by gas.
•  Carry out a gas test with the appropriate test gas.
• Attention! When using a lighter, only move the sensor head very slowly towards the gas source. A 100 % concentration exposure can destroy the sensor.
• If the gas is not detected, the device is not ready for use.
•  After the gas test, wait until the display shows “0”.

7.3 Use

• Make sure the gas to be detected is listed above.

• Only turn on the meter in an environment unpolluted by gas.
  Press and hold the “On / Off” key for about 1 second. The meter will vibrate and a signal tone will sound.

• Let the meter warm up for 40 seconds. The remaining time will be displayed.

• Select the desired sensitivity with the “H/L” key.

• Clean the areas to be examined from oil and dust. Oil and dust can impair the detection.

• Slowly move the sensor head to the area to be examined.

• If there is a gas leak, the instrument will signal that gas escapes (see chart below), depending on the sensitivity setting. Keep in mind the reaction time of at least 2 seconds. Move the sensor head back a little to exactly locate the leak.

• Switch off the meter after the leak detection. To do this, press and hold the “On / Off” key for about 1 second.

Further functions

8.1 Display backlight
You can activate or deactivate the display backlight by pressing the “Display backlight” key (5).
8.2 Auto zero
The “Auto Zero” key is used to activate or deactivate automatic zeroing.
Activating it improves sensitivity to the target gas and reduces the sensitivity to other existing gases which can influence the measurement.
8.3 Auto Power Off
The automatic power-off function switches off the unit after approx. 10 minutes of non-use to conserve the battery. With the “APO” key, this function can be deactivated.
8.4 Sensitivity
With the “H/L” key you can adjust the sensitivity according to your needs.
8.5 Alarms
Use the key with the vibration icon or with the speaker icon to switch the corresponding alarm on or off.
