Energy Pulse LED
The EM13X Series has 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 Device Options
setup. When in test mode, the energy and demand accumulators do
not account for consumed energy.
COMPort Activity LEDs
The meter has two yellow LEDs “RX” and “TX”, which indicate activity
on the COM1 communication port. The LEDs flash when the port is
receiving or transmitting data.
VOLTAGES LEDs
The meter has three green LEDs “L1, "L2" and "L3”, which indicate
voltage measurement input presence. When LEDs are "ON", that
means that the voltage measurement inputs exist in the meter
Navigation Buttons
The EM13X Series is provided with two push buttons that are normally
used to navigate between different measurement displays.
The "UP" and "DOWN" 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.
