Replacing batteries
Before using the GasCheck Tesla instrument ensure the
batteries
are fitted correctly or ensure NiMH
(rechargeable) batteries are fully charged before use.
To fit or replace batteries you must first remove the
battery cover from the rear of the instrument.
This can be done by prising open the battery clip with a
finger nail or screw driver.
Removing the battery cover will reveal a battery holder,
which requires 4 x AA size batteries. Before removing old
batteries or fitting new ones unclip the battery holder from
the instrument by prising apart the PP3 type clip shown in
the illustration.
Once the battery holder is disconnected from the
instrument, the batteries can be removed or replaced
however care must be taken when refitting the batteries
to ensure they are the correct polarity, polarity markings
are moulded on to the battery holder plastic.
The battery holder can be reconnected to the GasCheck
Tesla by firmly pressing the two halves of the PP3 clip
together. Care should be taken to ensure the polarity is
correct, see the PP3 diagram (right).
The battery pack is then laid within the instrument and
the battery cover refitted, be careful not to trap wires
when refitting the battery cover.
