How to Use
4-1. Before using the gas detector
Not only the first-time users but also the users who have already used the gas detector must follow the
operating precautions.
Ignoring the precautions may damage the gas detector, resulting in inaccurate gas detection.
4-2. Preparation for start-up
Before starting gas detection, check the followings.
Check that the protective film attached on the display from shipping is removed.
The batteries are installed (with sufficient battery level).
The dust filter is not contaminated.
The gas sampling probe is not loose.
The hose clamp coupler is connected securely.
<Installing and Replacing Batteries>
When the gas detector is used for the first time, or when the battery level is low, attach new AA alkaline
batteries according to the following procedures.
CAUTION
Turn off the power of the gas detector before replacing the batteries.
Replace the batteries in a non-hazardous area.
Replace all of the four batteries with new ones at one time.
Pay attention to the polarities of the batteries.
If the battery cover is not completely locked, the dry batteries may drop off or water may get in
through the clearance. Water may also get in if a minute foreign substance is caught beneath
the battery unit.
CAUTION
The display is covered by the protective film to prevent scratches from shipping.
Be sure to remove this film before use.
Gas monitor with this film will not satisfy the explosion-proof performance.
