Sec V, Sec I
: This is the default selection. This setting corresponds to the secondary voltage
probes and the secondary current probes (test switch probes, clamp-on probes, etc.). For
metering, this is the “power pair” that is used for calculating power and registration.
Sec V, Pri I
: This setting corresponds to the secondary voltage probes and the primary current
probes (flexible current probes, Amp Litewire, etc.). If the user wants to view the relationship
between the secondary voltage and the primary current, this is the correct selection. This setting
will change the “power pair” and power (W, VA, VAR) is calculated accordingly to the inputs
selected. If no primary probes are detected, this setting is not available.
Sec V, Pri V
: This setting corresponds to the secondary voltage probes, and the primary voltage
probes (Volt LiteWires).). If the user wants to view the relationship between the secondary
voltage and the primary voltage, this is the correct selection. This setting will change the “power
pair” and power (W, VA, VAR) is calculated accordingly to the inputs selected. If no primary
probes are detected, this setting is not available.
Neutrals
: This setting corresponds to a single secondary voltage probe and a secondary clamp-
on current probe (MN353 or MN375). This allows the user to view the secondary neutral phase
for the voltage and current. If no single clamp-on probe is detected, this setting is not available.
Enable Ratios
This function key can be found on the vector diagram and the power meter. The main job for this
key is to allow the user to view measurements with the CT and PT ratios enabled. When a CT
and PT are selected in the Site Editor, the ratios are used to calculate all power measurements
without the requirement of primary current and voltage probes.
Toggles between Connection View and Meter View
This function key can be found on the waveforms, vector diagram, power meter, harmonics, and
full analysis. The main job for this key is to allow the user to view the different signals according
to the meter installation. Meter View is the default display, and it displays the signals that are
internal to the meter. Connection View displays the signals as they are connected at the actual
terminals (i.e. test switch). While in Connection View, power is not calculated. Below is an
example of a 3-Phase, 4-Wire WYE (2V, 3C) Z-coil TR – S009F06 using both Meter View
(default) and Connection View:
