RATE
Rate A
is the voltage or current input converted to a frequency output of 0 to 100kHz.
The period of the frequency is measured and converted to a rate by 1/period and
applying Scale1 and Offset1. Scaling may also be set by using coordinates of 2 points
where low and high input signals and the corresponding low and high displayed values
are entered.

12.3

BATCH
Batch
displays total of voltage or current input as item 1, grand total or number of
batches as item 2 and rate as item 3. Relay #1 is used as the Batch Controller. This
leaves Relay #2 for use as either Pre-warn, End-of-process or Rate alarm. When reset
in the batch mode, the counter resets and then displays "rEAdy". It waits until the reset
button is pushed and then immediately energizes Relay #1 and starts displaying the
batch total. When the preset value is reached, Relay #1 de-energizes for a period of time
equal to the Time out setting. At the end of time out, the Batch Total resets, Relay #1
energizes and the cycle repeats.
As an option, the cycle can be reset from an external signal Function Reset. The Time
Out is not used and Relay #1 remains de-energized until the Function Reset external
input is grounded for a minimum of 3.33 mS. Sometime during that period, the Batch
Total is reset and Relay #1 is energized.
The Batch Total is displayed as Item #1 and may be configured to count up from 0 to
