two modes. The first is using a time base. This can be used to compute a time-
temperature product. The second is through a user input or function key
programmed for Batch (one time add on demand). This can be used to provide
a readout of temperature integration, useful in curing and sterilization
applications. If the Totalizer is not needed, its display can be locked-out and this
module can be skipped during programming.

and engineering units as the Input Display. In these cases, the Totalizer Scale
Factor is 1.000. The Totalizer Scale Factor can be used to scale the Totalizer to
a different value than the Input Display. Common possibilities are:

TOTALIZER HIGH ORDER DISPLAY
this case, the meter continues to totalize up to a 9 digit value. The high order 4
digits and the low order 5 digits of the total are displayed alternately. The letter

TOTALIZER BATCHING
function key is programmed for store batch (
input or function key is activated, the Input Display reading is one time added
to the Totalizer (batch). The Totalizer retains a running sum of each batch
operation until the Totalizer is reset. This is useful in weighing operations, when
the value to be added is not based on time but after a filling event.
TOTALIZER USING TIME BASE
Example: The input reading is at a constant rate of 10.0 gallons per minute. The

Where:
Totalizer is used to determine how many gallons in tenths has flowed.
Because the Input Display and Totalizer are both in tenths of gallons, the
Totalizer Scale Factor is 1. With gallons per minute, the Totalizer Time Base
is minutes (60). By placing these values in the equation, the Totalizer will
accumulate every second as follows:
10.0 x 1.000 = 0.1667 gallon accumulates each second
This results in:
