F F LE-01MR v2 Electric Energy Meter

Functioning

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. 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.

Modbus registers

Description of measurement and configuration registers availa-ble on the website www.fif.com.pl (on the device’s subpage).

Meter address

Change of meter address and connection parameters is done via the RS-485 using the touch button on the front of the casing of the meter.

Meter number

The meter is marked with individual serial number allowing its unambiguous identification. The marking is laser engraved and cannot be removed).

Sealing

The meter has sealable input and output terminal covers to pre-vent any attempts to bypass the meter.
