Technical specifications

0.001% vol 0.001% LEL

% LEL: is the limiting concentrations of gas (in air) that is needed for the gas to ignite and explode.
Example for CH4 gas: 100% LEL = 5% vol
% vol: is the concentrations of gas (in air) expressed in percentage of volume in air.
Example for CH4 gas : 1% vol = 10 000 ppm

Perform a measurement

• Turn on the device by pressing on “On/Off/Esc”.
  The device displays its name “FG110”. When it turns on, the device emits a beep then performs a pre-heating phase. This phase lasts 60 seconds. The count of this pre-heating time displays on screen.

• During the normal functioning, in the absence of gas leak, the device emits a regular beep*.

• Otherwise, if the device detects the presence of gas, the repetition frequency of the beep will increase as the detected concentration in

Freeze the measurement

During a measurement:

• Press once on “Hold/min/max”.
  “Hold” appears on screen and the measurement is frozen.

• Press on “On/Off/Esc” to exit the hold function. The device returns to the measurement display.

Display the minimum and the maximum

Once the measurement is frozen:

• Press on “Hold/min/max”.
  The device displays the maximum value measured since the last questioning at the top of the screen and the minimum value measured since the last questioning at the bottom of the screen.

• Press on “On/Off/Esc” to return to the measurement display

Adjust the alarm

This function allows to activate an alarm. When the device detects a leak, it emits a beep whose frequency is increasingly fast as and when the concentration increases and gets closer to defined alarm threshold. The beep becomes continuous when the device reaches and exceeds this threshold. This threshold is between 1000 and 10 000 ppm.
The device is on and displays the measurement.

• Press on “Select” until “AL 1” blinks on screen.

• Press on “OK”.
  A succession of 5 zeros displays and the first zero blinks.

• Press on “Select” to select the first digit value : 0, 1 or Off.

• If 1 is selected, the maximum threshold (10 000 ppm) is reached. Press on “OK” until “AL 1” blinks on screen.

• If Off is selected, the alarm is deactivated. Press on “OK” to validate, “AL 1” blinks on screen.

• If 0 is selected, the following digit blinks. Press on “Select” to select its value, then press on “OK”. The following digit blinks, perform the same procedure. Press on “OK” when the last digit value is selected, “AL 1” blinks on screen.
