BARTINGTON INSTRUMENTS
Page 19 of 82 OM0408/49
For units purchased after 1st January 2006, the holes are no longer filled with wax. A small
Philips screwdriver must be used to release the enclosure halves. The top half of the enclosure
can now be carefully lifted away from the unit.
Caution:
Before opening the enclosure, ensure that the instrument is turned off and not
connected to the mains power.
Caution:
Take care not to disconnect the earth lead between the two halves of the
enclosure.
Note:
It is recommended to disconnect and lift PC7 off (4 screws), and lift rear panel out
while assembling the new battery pack.
Disconnect and remove the battery. On later batteries the connection is via a two-way connector.
On older units the connection is via a terminal block with screw terminals. The terminal block
forms part of the battery assembly, and must be removed with the battery to avoid the possibility
of shorting the battery and creating a potential fire risk. Once the battery has been disconnected,
remove the terminal block: this will be used on the replacement battery.

Key to Figure 4
1. Double sided foam
Note:
The double-sided adhesive foam that holds the battery in place should be replaced
when the battery is replaced. The old foam can be removed using isopropanol cleaning
solvent.
WARNING:
On no account use acetone as this will dissolve the enclosure.
Once dry, apply new strips of double sided foam (supplied with the replacement battery).
Insert the replacement battery and reconnect.
