TOTALIZERS Calculates total and grand total 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. The total and grand total utilize the
same time base, with different conversion factors and resets.
TOTALIZER
RESET Via SafeTouch ® RESET button, mechanical button (cover off), external contact
closure (total only), automatically via user selectable preset value and time delay
(1 – 99,999 sec). Manual reset may be disabled or protected by password for the
