Maintenance
1. Refer to Figure 6. Turn over the GasCheck so that the battery compartment is at the top: see detail A.
2. On the GasCheck 3000, use a small coin, screwdriver or your fingernail to press the catch (1) on the
battery compartment cover (2), then pull up and remove the cover: see detail B.
On the GasCheck 3000is, use the special screwdriver supplied to undo the captive screw on the battery
compartment cover and remove the cover. This is located at the end of the GasCheck at position (5).
3. Remove the battery holder from the GasCheck. If required, you can carefully unplug the battery holder
so that you can detach the holder from the GasCheck.
4. Remove the old batteries (4) from the battery holder. Dispose of the batteries (see section 6.2).
5. Inspect the inside of the battery compartment and battery holder. If the batteries have leaked, use a cloth
dampened with a weak solution of detergent to clean the battery compartment and battery holder.
6. Fit four new batteries in the battery holder. Ensure that you fit the batteries in the correct orientation. To
reduce the risks of incorrectly connecting the battery clip remove one battery before you refit the battery
holder to the GasCheck. You then add the fourth battery into the clip before pushing it into the battery
compartment.
7. On GasCheck 3000, refit the battery compartment cover (2) and ensure that the catch (1) is engaged.
On the GasCheck 3000is, refit the battery compartment cover and use the special screwdriver to tighten
the captive screw and secure the cover in place.
8. Switch on the GasCheck to ensure that the batteries are correctly fitted. If the display remains blank
when you switch on the GasCheck, refer to section 5.3.
CAUTION
Ensure that the screw is located squarely to the threaded insert before tightening else the
battery compartment cover may not be properly secured due to cross threading. The
instrument will then have to be returned to the supplier for replacement of the GasCheck
case including a new serial number.
CAUTION
The GasCheck 3000is will blow a factory fitted internal protection fuse if the battery clip is
inadvertently reverse connected. The complete instrument will have to be returned to the
supplier for fuse replacement. The GasCheck 3000 has an internal self-resetting fuse. Please
do use care.
