Basic Setup Menu
The Basic Setup menu contains values that typically do not need to be reconfigured
once the meter is put into service. The Basic Setup menu item provides access to the
following power monitoring system settings:
1
Polarities can be normal or inverted.
2
Applicable to meters ordered with the current probe input option.
All Basic Setup menu items are setup registers in the Power Meter module. See the
online ION Programmer’s Reference for details.
The Current Probe phase calibration registers are setup registers in the Factory
module that can be configured in a Telnet or HyperTerminal session. Up to three
separate groups of registers (Factory Default, User Defined 1, and User Defined 2) can
be set up for three different Current Probes. In the Basic Setup menu, the Probe Type
register is used to activate one of those register groups. Only the selected group is
used in the meter’s calculations.
