Read the instructions for each individual gas detector before using. The following is an example method and slight variations will occur between models.
Step 1 – Turn on gas detector
Press the power button to activate the device.
Step 2 – Wait for calibration
Lights will flash to signal the device is calibrating. Wait for these to stop before continuing.
Step 3- Set gas detector
Use the appropriate buttons to switch your gas detector to the required setting. For example press the high sensitivity button to detect small concentrations of gas. You may also wish to alter which indicators are active: you may wish to turn off the audible alert.
Step 4 – Test gas detector
Position the sensor as appropriate (usually fully-extended) and use a known gas source to check your gas detector is working correctly, perhaps a gas hob or torch. If the detector does not begin to alert, do not continue use.
Step 5 – Detect gas
After the device has stopped sensing the known gas source, move it around the area where you suspect there may be gas, concentrating on joints and connections.
