This selects the decimal point position for Counter A. The selection will also

affect Counter A scale factor calculations.

COUNTER A SCALE FACTOR

CmtA ScF 

 01.0000

00.0001 to 99.9999

The number of input counts is multiplied by the scale factor to obtain the

desired process value. A scale factor of 1.0000 will result in the display of the

actual number of input counts. (Details on scaling calculations are explained at

the end of this section.)*

COUNTER A COUNT LOAD VALUE

Counter A resets to this value if Reset to Count Load action is selected.

COUNTER B BATCH COUNT ENABLE

SP1 SP1-2

The Counter B batch count function internally counts the number of output

activations of the selected setpoint(s). The count source for the batch counter

can be SP1, SP2 or both. Batch counting is available in all count modes except

Dual Counter, which uses an external input signal for Counter B. This

parameter only appears if a Setpoint Output option card is installed.

COUNTER B DECIMAL POSITION

affect Counter B scale factor calculations.

COUNTER B SCALE FACTOR

Cntb ScF  00.0001 to 99.9999

 01.0000

The number of input or batch counts is multiplied by the scale factor to

obtain the desired process value. A scale factor of 1.0000 will result in the

display of the actual number of input or batch counts. (Details on scaling

calculations are explained at the end of this section.)*

When Counter A is reset, it returns to Zero or Counter A Count Load value.

This reset action applies to all Counter A resets, except a setpoint generated

Counter Auto Reset programmed in Module 4.

The selected counter(s) will reset at each meter power-up.

* For value entry instructions, refer to selection/value entry in the Programming

The Meter section.
