BLE 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 automati-

before the total is reset.
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.
TOTAL RESET
PASSWORD Total and grand total passwords may be entered to prevent
resetting the total or grand total from the front panel.

Caution!
Once the Grand Total has been programmed
as “non-resettable” the feature cannot be
disabled.
