1.2 EQUIPMENT

The equipment is fitted with a control console containing a blue 4 line by 40-character backlit LCD
display and a membrane keypad. The LCD can display the test set-up, test procedure and test results
in various languages as selected by the user.
The equipment can be used stand-alone or can be connected to a PC running the optional NEXYGEN
Plus software.
When a test is performed in the stand-alone mode, the test results are stored using a Date-Time ID that
is created from the internal clock inside the equipment.
This internal clock has been set during the production process at Davenport / Lloyd Instruments Ltd but
should be checked during the initial installation. Note that if the equipment is used with the NEXYGEN
Plus PET software, then the internal clock will be automatically synchronised to the PC clock when the
software is connected to the equipment.
The internal clock always operates on UTC (GMT) time so the time displayed on the control console
should be altered if the local time is not UTC, e.g. British Summer Time or if the equipment is used in a
country other than the UK.
The equipment can store up to 600 test results internally and the statistics and results can be easily
viewed on the control console display. If 600 tests are already stored, then when the next test is
performed, the first test will be deleted to allow the new test to be stored. This feature allows the last
600 test results to be stored.
There are connection points on the cabinet for the nitrogen gas supply and the optional computer.
A fused switched socket is fitted for connection to the mains electricity supply.
Ancillary equipment developed for use with the PET Plus to handle the grinding, drying and transfer of
samples is available as either a package or as individual items.

1.3 EQUIPMENT OPERATION
