Total Reset Capabilities
The total and grand total can be reset using a
CapTouch button, an external contact closure on the
digital input, or MeterView XL software. In addition,
both total and grand total reset can be password
protected to prevent unauthorized resets.
Total Reset via CapTouch Button
The CapTouch function key F2 is set up to reset the
total. If reset grand total is enabled, it is possible for the
user to reset either the total or the grand total without
removing the cover or the need for external devices.
Total Reset via Digital Input
The PD6928’s digital input can also be used to reset the
total or grand total.
Total Reset Password Protection
Total and grand total passwords can be set to prevent
resetting the total or grand total unless a password is
entered. Grand total reset can be disabled through
the meter interface, and it can also be permanently
disabled. See
Non-Resettable Grand Total
The user can set up the grand total to be non-resettable by
selecting
YES
at the
PERMLOC
menu; see page 62 for
details. Once this is done, the grand total can never be reset.
