Chapter 4 Setup Menus 38
4.11 Reset/Synchronization Menu
This menu allows you to reset to zero the accumulators and Min/Max registers in
your instrument, and also to synchronize the power demand interval. The menu
can be only accessed via the
Setup Change Menu (CHG) . If the reset is disabled
from the Basic Setup Menu (see Section 4.1), you will not be able to enter this
menu.
The following designations are used in the menu to specify a data location to be
affected:
EnrG Resets total accumulated energies
dnd Resets all total maximum demands
P.dnd Resets total power maximum demands
A.dnd Resets volt/ampere maximum demands
Cnt Resets all event/time counters
Cnt.1 Resets counter # 1
Cnt.2 Resets counter # 2
Cnt.3 Resets counter # 3
Cnt.4 Resets counter # 4
Lo.Hi Resets Min/Max registers (does not affect maximum demands)
d.Snc Provides synchronization of the power demand interval (see NOTES below)
To reset the desired locations:
Press to activate the middle window, and then use
the up/down arrow keys to scroll to the desired data location
entry.
Press to activate the lower window.
Press and hold for about 5 seconds until the
do label
is replaced with done , and then release the key. You will return
to the middle window.
Press to quit the menu.
NOTES:
1. If the CHG menu is not secured by a password, fast reset of the Min/Max registers,
maximum demands and energies can be done from the data display mode (see Section
5.1) and counters from the Status Information Menu (see Section 6.1) without entering
the reset menu.
2. If you select the d.Snc entry, take into consideration the following:
- Synchronization of the instrument’s internal timer requires that the power demand
period be specified in minutes (see Section 4.1, Basic Setup Options). If more than 30
seconds pass from the beginning of the current demand interval, the new demand
interval starts immediately; otherwise synchronization is delayed until the next demand
interval.
- Synchronization occurs exactly 5 seconds from the time you first pressed
while you hold the key.
