2.5 REPLACING THE INSTRUMENT IN ITS HOUSING
To replace the instrument, simply align the CPU PCB and Power Supply PCB with their
guides and connectors in the housing and slowly but firmly push the instrument into
position.
CAUTION: Ensure that the instrument is correctly orientated. A stop
will operate if an attempt is made to insert the instrument in the wrong
orientation (e.g. upside-down). This stop must not be over-ridden.
2.6 SELECTION OF INPUT TYPE
The required input type is selected on link jumpers LJ1/LJ2/LJ3 on the CPU PCB (see
Figure 2-6 and Table 2-1).
