WARNING
Replace the batteries in the Gas Check 5000is in a safe area where there are
no flammable gases. If you do not, there may be a risk of fire or explosion.
WARNING
Use only dry cell (non-rechargeable AA) batteries or Ion Science AAA Rechargeable Battery
Pack (part No. A-31117) in the GasCheck 5000is. The internal
resistance of unpotted rechargeable batteries is too low to maintain a T4 safety rating.
The recommended batteries are specified in Battery Data.
CAUTION
The Gas Check 5000is will blow a factory fitted internal protection fuse if the battery clip is
reverse connected. The complete instrument will have to be returned to the supplier for fuse
replacement.
Ensure that the rubber sleeve on the female part of the battery holder is correctly fitted when
you fit new batteries. If you do not, you could refit the holder in the Gas Check 5000is with
incorrect polarity, which will blow an internal fuse and make it inoperative.
Note: A spare battery holder is supplied in the case.
