Meter Resets
The Meter Resets menu item allows you to clear the cumulative parameters stored
by the meter. You are required to enter a valid meter password before executing
any meter resets.
Factory Resets
This sub-menu contains the following default resets:
peak dmd rset
The Peak Demand Reset allows you to clear the peak demand values logged in the
meter. When the meter is in test mode, the Demand Reset object clears the Revenue
Test Mode demand parameters.
N OTE
See “Revenue Measurements” on page 97 for more information about TEST mode.
By default, there is a 25 day Demand Lockout Time. This is the minimum time
allowed between consecutive demand resets. Any attempts to perform a demand
reset before the lockout time has expired will be ignored. See “Demand Setup
Menu” on page 34 for details about reconfiguring the default Demand Lockout.
MNMX RSET
The Minimum/Maximum Reset allows you to clear all accumulated minimum and
maximum values stored in the meter.
HARM MNMX RSET
The Harmonics Minimum/Maximum Reset allows you to clear all accumulated
minimum and maximum harmonics values stored in the meter.
MASTER RESET
The Master Reset control allows you to clear all the cumulative and derived
quantities from the meter (including demand, peak demand, energy, revenue, and
test mode parameters), clear the meter’s event and waveform logs, and reset the
meter’s Data Recorder modules.
C AUTION
The Master Reset operation will clear all billable quantities from the meter, all logged data from the
meter’s event and waveform logs, and all data recorders. Carefully consider the implications of
performing a Master Reset before proceeding.
DI COUNT RESET
The DI Count Reset allows you to clear the Digital Input Status Change counter.
By default, the number of status changes of each digital input is shown in the
D Inputs front panel display as well as in the Vista Digital Inputs/Outputs diagram.
