LE-01MR v2
Electric energy meter,
1-phase
MID Directive 2014/32/EU
Certificate 0120/SGS0305
The LE-01MR v2 is a static (electronic), calibrated AC single-pha-
se electricity meter for direct current measurement in a 2-wire
system.
The meter provides 4-quadrant energy and power measurement
as well as monitoring of many additional network parameters
such as voltage, current, active power, reactive power, apparent
power, frequency, power factor. The meter has additional, era-
sable active and reactive energy meters. It is also equipped with
RS-485 communication interface with Modbus RTU protocol
support for remote meter reading and configuration. The touch
button located on the front panel of the meter allows you to
select the displayed parameter and change the meter settings.

Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.

The backlit LCD display makes it easy to read the measured
values.
The parameter is changed by default every 5 seconds or at the
frequency set by the user and manually, using the touch button
on the front of the casing of the meter.
The display is active when the indicator power is on.
