The Totalizer can be reset to zero on each meter power-up by setting this

parameter to reset.

TOTALIZER HIGH ORDER DISPLAY

When the total exceeds 5 digits, the front panel annunciator flashes (if

assigned to A, B, or C display). In 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 “

h

” denotes the high order display.

TOTALIZER BATCHING

The Totalizer Time Base and scale factor are overridden when a user input or

function key is programmed for store batch (

bAt

). In this mode, when the user

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

Totalizer accumulates as defined by:

Input Display x Totalizer Scale Factor

Totalizer Time Base

Where:

Input Display - the present input reading
Totalizer Scale Factor - 0.001 to 65.000
Totalizer Time Base - (the division factor of

tbASE

)

Example: The input reading is at a constant rate of 10.0 gallons per minute. The

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

60

This results in:

10.0 gallons accumulates each minute
600.0 gallons accumulates each hour

TOTALIZER SCALE FACTOR CALCULATION EXAMPLES

1. When changing the Totalizer Decimal Point (

dECPt

) location from the

Input Display Decimal Point (

dECPt

), the required Totalizer Scale Factor is

multiplied by a power of ten.

Example: Input (

dECPt

) = 0.0 Input (

dECPt

) = 0.00

(x = Totalizer display is round by tens or hundreds)

2. To obtain an average reading within a controlled time frame, the selected

Totalizer Time Base is divided by the given time period expressed in the same
timing units.

Example: Average flow rate per hour in a 4 hour period, the scale factor

would be 0.250. To achieve a controlled time frame, connect an external timer
to a user input programmed for

rtot2

. The timer will control the start (reset)

and the stopping (hold) of the totalizer.
