BATTERY AND OPTIC MAINTENANCE

Cleaning the Optics

Regular cleaning of the optics will maintain and optimise the
accuracy of the SPLIT2.

Switch off the unit and disconnect the sensor from the unit

Remove the sensor from the back plate by unscrewing
the two retaining screws.

Unscrew the 3 retaining screws on the light chamber.

Remove the light chamber cover.

This allows access to the emitter and receiver lenses.

Clean the lenses with Isopropyl Alcohol using a cotton bud

If required the chamber can also be cleaned  with compressed
air, of the type used to clean cameras  lenses.

Replace the light chamber cover and retaining screws.

Remount the sensor on the back plate using the two
screws

An AutoZero should now be performed. see p14.

This instrument operates on a rechargeable NiMH battery pack.
This  is recharged while in the unit, using the jack socket and
charger supplied.

Please note that the battery charger provided is not

recommended for use as a mains adaptor.

The SPLIT2 has a Lithium battery back up for data retention even
if the main batteries are exhausted or not fitted.

Should it be necessary to replace the battery pack, it is located in
the side panel.

Unscrew the two battery compartment retaining screws
and slide out the battery holder.

Unclip the connector and remove battery pack

Replace with a suitable SPLIT2 battery pack.

Take full advantage of all the SPLIT2 features. Save data, create reports, and much more.

Use of the software is covered in the separate manual also included on the CD.
Please  read through the software manual before attempting to install the software to your PC.
