2. Set up the rate, total, and grand total engineering units for channels A & B, and units for math channel C
3. Set up rate, total, and grand total decimal points for channels A & B, and decimal point for math channel C
4. Program channel A & B rate parameters
5. Program channel A & B total and reset parameters
6. Set up the display line 1 and line 2
7. Select the transfer function for A & B (e.g. Linear)
8. Select Math function for Channel C

Total Display & Total Overflow: 0 to 999,999; automatic lead zero blanking. Up to 999,999,999 with total-overflow feature. "oF" is displayed to the left of total overflow and ▲ LED is illuminated.
Total Decimal Points: Up to five decimal places or none: d.ddddd, d.dddd, d.ddd, d.dd, d.d, or dddddd. Total decimal point is independent of rate decimal point. Channel A and B decimal points programmed independently.
Dual Totalizer: Calculates total for channels A and B based on rate and field programmable multiplier to display total in engineering units. Time base must be selected according to the time units in which the rate is displayed. Channel A and B totalizer parameters programmed independently.
Totalizer Rollover: Totalizer rolls over when display exceeds 999,999,999. Relay status reflects display.
Total Overflow Override: Program total A or B total reset for automatic with 0.1 second delay and set point 1 for 999,999
Totalizer Alarm Presets:Up to eight, user selectable under setup menu. Any set point can be assigned to channel A or B total or grand total (or C) and may be programmed anywhere in the range of the meter for total alarm indication.
Total & Grand Total Reset: Via front panel button, external contact closure on digital inputs, automatically via user selectable preset value and time delay, or through serial communications. Channel A and B total and grand total reset parameters programmed independently.
Total Reset Password: Total and grand total passwords may be entered to prevent resetting the totals or grand totals from the front panel.
Non-Resettable Total: The grand totals can be programmed as non-resettable totals by entering the password "050873". Both channels are set to non-resettable when this password is entered.
CAUTION! Once the Grand Totals have been programmed as "non-resettable" the feature cannot be disabled.
Programmable Delay On Release: 0.1 and 999.9 seconds; applied to the first relay assigned to total or grand total.
If the meter is programmed to reset total to zero automatically when the preset is reached, then a delay will occur before the total is reset.
