Load Bar Graph
The load bar graph displays the amount, in percent (40% to 110%), of
the present current load with respect to user-defined nominal load
current. The reference nominal current can be set up in amps through the
display setup (see
). If it is set to 0 (default), the
current load is referenced to the specified CT primary current.
Energy Pulse LED
The PM130E and PM130EH have a red “Energy Pulse” LED. It flashes at a
constant rate when a load is applied to the meter.
There are two modes of LED operation:
NORMAL mode: the LED pulses indicate imported Wh at a rate
of 1,000 pulses per kWh
TEST mode: the LED pulses indicate either imported Wh, or
imported (inductive) varh at a rate of 10,000 pulses per
kWh/kvarh
The energy test mode can be enabled through the
When in test mode, the energy and demand accumulators do not account
for consumed energy.
Port Activity LEDs
The meter has two green LEDs “RX” and “TX”, which indicate activity on
the COM1 communication port. The LEDs flash when the port is receiving
or transmitting data.
Navigation Buttons
The PM130 is provided with six push buttons that are normally used to
navigate between different measurement displays.
The function of buttons changes depending on what operating mode the
display is in. In programming mode, the buttons access the device setup
menus where the default factory-set device settings can be changed.
3.2 Data Display
In data mode, the display is normally updated once every second. You can
adjust the display update rate via the display setup (see
Display Features
Measurement Units
The PM130 PLUS has a selectable resolution for volts, amps and powers
presented on the front display and via communications. See
in Chapter 5 for information on selecting the data resolution in the
PM130 PLUS.
Low Resolution Option
Currents are displayed in whole amperes below 10,000 A, and in kilo
amperes above 10,000 A.
Measurement units for voltage and power depend on the voltage
connection scheme:
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.
