Recommended Spare Parts
6.2
Items marked * are not consumable – therefore only one set of these items
needs to be held as back-up spares for each analyser type. All other items have
a limited life and full quantities will be required for each individual analyser.
Fault-Finding
6.3
The electronics require no routine maintenance. They are all solid state and
undergo a rigorous factory burn-in procedure. If there is any doubt about the
equipment performance the signal processor may be interrogated from the
keypad to determine whether or not the equipment is functioning normally.
Should a recognised fault occur the display switches from its current mode of
operation to the diagnostic mode and display the current fault condition – see
Data Valid LED Out. If this fault clears, the display will stay in the diagnostic
mode and display the ‘All Clear’.
Enter the diagnostic mode from the keypad of the instrument; this can be done
at any time without interrupting or disturbing the analogue outputs of the
equipment.
As an initial guide to equipment performance, typical values for instrument
operation are given below :
