How to install option boards
If you want to open the meter to install or modify option boards, follow these
steps...
1)
Switch off power to the meter and unplug all connectors.
2)
Unclip the front bezel. This is easier if you squeeze the top and bottom of
the case, near the front.
3)
Remove the small screws shown in the diagram. If the meter doesn’t yet
have an output option board, the top screw may not yet be fitted.
4)
Slide the electronic boards out throught the front of the case. You can easily
separate the upper option board from the
main board. We strongly suggest that you
use anti-static precautions toprevent
damage to the semiconductors.
The board assemblies will look something like this...
The analogue output and RS232 or RS422 plug-in option boards are fixed to the
upper option board with white plastic pillars. You must apply a firm force when
fitting or removing these options.
Always be careful to connect the pins to sockets accurately. When reassembling,
make sure option boards are firmly fixed to the upper option board. When the
boards are replaced in the case, secure them again with the two small black
screws.
