Chapter 4 Setup Menus 31
4.9 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 in the PM130E. 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 menu uses the following labels:
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; 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; release the key.
You will return to the middle window.
Press to quit the menu.
NOTES:
If you select the d.Snc entry, take into consideration the following:
1) If the power demand period is specified in minutes (see Section 4.1,
Basic Setup Options), this action provides synchronization of the
instrument’s internal timer. If the time expired from the beginning of the
current demand interval is more than 30 seconds, the new demand
interval starts immediately, otherwise synchronization is delayed until
the next demand interval.
2) The synchronization is made exactly 5 seconds after you first press
and hold .
If the CHG 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.
