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

Certificate number
Purpose
The LE-03MQ CT is a static (electronic) calibrated electricity me-
ter of single-phase or three-phase alternating current in a semi-
-direct system.
It is used for reading and recording of imported electricity and
parameters of the power supply with the ability of remote reading
through a wired RS-485 network.
The meter works with current transformers (CT) with a seconda-
ry current of 1 A or 5 A.
Configuration of the meter is done through the configuration
menu accessible from the front panel and through the commu-
nication port according to the software features of the Modbus
RTU.
