PM130 PLUS Powermeter Series
For direct wiring (PT=1) or wiring via PT with the PT ratio up to and
including 4.0, voltages are displayed in volts, and power in kilowatts.
For the PT ratio above 4.0, voltages are displayed in kilovolts with
three decimal places, and power in megawatts with three decimal
places.
High Resolution Option
Currents are displayed in amperes with up to two decimal places below
10,000 A, and in kilo amperes above 10,000 A.
Measurement units for voltage and power depend on the voltage
connection scheme:
When direct wiring is used (PT=1), voltages are displayed in volts
with one decimal place, and power in kilowatts with three decimal
places.
When wiring via PT is used with the PT ratio up to and including 4.0,
voltages are displayed in volts, and power in whole kilowatts.
For the PT ratio above 4.0, voltages are displayed in kilovolts with
three decimal places, and power in megawatts with three decimal
places.
The small round “Kilo” and “Mega” LEDs light up showing the appropriate
measurement units for a displayed page.
Primary and Secondary Volts
Volts can be displayed in primary (default) or secondary units. The volts
display mode can be changed through the display setup (see
Phase Power Readings
In configurations with the neutral wire, in addition to total three-phase
powers, the meter can show per-phase power readings. By default, they
are disabled. See
power readings in your meter.
Fundamental Component
The PM130EH can display total displacement power factor and active
power for the fundamental component if it is enabled through the display
setup (see
When phase power readings are allowed, the PM130EH also displays per-
phase displacement power factor and active power for the fundamental
component.
Auto Return
If no buttons are pressed for 30 seconds while the display Auto Return
option is enabled, the display automatically returns to the main screen
from any other measurement display.
The Auto Return option can be enabled through the display setup (see
Auto Scroll
If no buttons are pressed for 30 seconds while in the common
measurements display, and the Auto Scroll option is enabled in the meter,
the display automatically scrolls through all available pages. The scroll
interval can be adjusted through the display setup (see
