balances. There are three basic configurations of balances: Analytical, Precision Top Loader
and High Capacity Top Loader. The High Capacity Top Loader balances are rated from 12,000 grams to 32,000 grams
capacity and contain different components than the lower capacity Precision Top Loader balances. The procedures in this
manual assume the technician performing them has a working knowledge of the use of standard hand tools and the repair
and use of precision instruments.
The service strategy for Explorer balances is the replacement of PC boards, membrane switches and most case parts. The
transducers are to be repaired. Only parts listed in the parts list are replaceable.
To service an Explorer Pro or Voyager balance, the display module must be removed and an Explorer display module
substituted. This is required in order to use the service software that is in the processor that is located on the Main PCB.
See illustration below.
