6.10.2 Accumulator Types
The module supports a total of 12 accumulators per meter channel divided into
the following categories:
These 3 accumulator types are independent. For example, resetting a resettable
accumulator does not affect the other accumulators.
For multiple-stream firmware (version 2.05 and later), each stream also has its
own set of ten accumulators (six non-resettable and four resettable). Increments
are applied both to the meter accumulators and to the accumulators for the active
stream.
Non-Resettable Accumulators
The non-resettable accumulators are only reset when the accumulator rollover
value is reached. The accumulator rollover value, and the accumulator unit must
be configured using the AFC Manager. Refer to the AFC Manager User Manual
for more information about this topic.
The module supports six non-resettable accumulators in order to show the
measured quantity to be totalized:

Non-resettable accumulator mass
 Non-resettable accumulator energy (Gas applications only)
 Non-resettable accumulator net
 Non-resettable accumulator gross
 Non-resettable accumulator gross standard (Liquid applications only). For Oil-
Water Emulsion, this is non-resettable accumulator gross clean oil.
 Non-resettable accumulator water (Liquid applications only)
Refer to the Modbus Dictionary dialog box in AFC Manager for more information
about the Modbus addresses for these registers.
Resettable Accumulators
The resettable accumulators are referred to as:

Resettable Accumulator 1
 Resettable Accumulator 2
 Resettable Accumulator 3
 Resettable Accumulator 4
Configuring Resettable Accumulators
Resettable Accumulators are configured from the Resettable Accumulator Select
dialog box. To open this dialog box, click the Resettable Accum button on the
Meter Configuration dialog box.
