LE-01MR
Electric energy meter,
1-phase
MID Directive 2014/32/EU
Certificate 0120/SGS0305
The LE-01MR is a static (electronic) calibrated electricity meter
of single-phase alternating current in direct system.
It is designed to indicate and register the consumed electricity
and parame-ters of the power supply network with the option of
remote reading of indications via RS-485 network.
The LE-01MR meter precisely measures the amount of consu-
med electricity under the influence of flowing current and ap-
plied voltage. Power consumption is indicated by the flashing
LED (1000 pulses/kWh). In addition, the meter measures the pa-
rameters of the supply network and the temperature of its own
system. The values are indicated cyclically on the LCD display.

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 parameter is changed by default every 5 seconds or at the
frequency set by the user and manually, using the button on the
front of the casing of the meter. The display is active when the
indicator power is on.
The meter operates in the communication network as a Slave
device.
The communication takes place in accordance with the Modbus
RTU standard via the RS-485 serial port. The read-out values of
registers after conversion give results according to the indica-
tions on the indicator display.

Change of meter address is done via the RS-485 port using the
Modbus RTU protocol command to set the desired value in the
meter register. The default meter address: 1.
The meter is marked with individual serial number allowing its
unambiguous identification. The marking is laser engraved and
cannot be removed).
The meter has sealable input and output terminal covers to pre-
vent any attempts to bypass the meter.
