PARAMETER MENU
TOTALIZER DECIMAL POINT*
For most applications, this matches the Input Display Decimal Point
(
). If a different location is desired, refer to Totalizer Scale Factor.
TOTALIZER TIME BASE
This is the time base used in Totalizer accumulations. If the Totalizer is being
accumulated through a user input programmed for Batch, then this parameter
does not apply.
TOTALIZER SCALE FACTOR*
For most applications, the Totalizer reflects the same decimal point location
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:
1. Changing decimal point location (example tenths to whole)
2. Average over a controlled time frame.
Details on calculating the scale factor are shown later.
If the Totalizer is being accumulated through a user input programmed for
Batch, then this parameter does not apply.
TOTALIZER LOW CUT VALUE*
to
to
A low cut value disables Totalizer when the Input Display value falls below
the value programmed.
TOTALIZER POWER UP RESET*

Do not reset buffer
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
TOT flashes. 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
“
” denotes the high order display. When the total exceeds a 9 digit value, the
Totalizer will show “E . . .” and will stop.
TOTALIZER BATCHING
The Totalizer Time Base and scale factor are overridden when a user input or
function key is programmed for store batch (
). 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
)
Example: The input reading is at a constant rate of 10.0 kilograms per minute
moving across a scale. The Totalizer is used to determine how many
kilograms in tenths has traveled over the scale. Because the Input Display
and Totalizer are both in tenths of kilograms, the Totalizer Scale Factor is 1.
With kilograms 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 kilograms accumulates each second
60
This results in:
10.0 kilograms accumulates each minute
600.0 kilograms accumulates each hour
TOTALIZER SCALE FACTOR CALCULATION EXAMPLES
1. When changing the Totalizer Decimal Point (
) location from the
Input Display Decimal Point (
), the required Totalizer Scale Factor is
multiplied by a power of ten.
Example:
Input (
) = 0 Input (
) = 0.0 Input (
) = 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 temperature 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
. The timer will control the start (reset)
and the stopping (hold) of the totalizer.

The totalizer accumulates (integrates) the Input Display value using one of
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.
