* F&F LE-01MR - This is a single phase energy meter with rs485 modbus interface
|
2020-01-05 00:06:30 +00:00
|
|
|
* (and bidirectional energy counting - enabled by RS485).
|
|
|
|
* It measure: Active energy imported AE+ [kWh] , Reactive energy imported RE+ [kvarh],
|
|
|
|
* Voltage V [V], Current I [A], Frequency F [Hz], power factor (aka "cos-phi"),
|
2020-01-23 15:13:25 +00:00
|
|
|
* Active power P [kW], Reactive power Q [kVAr], Apparent power S [kVA],
|
2020-02-10 14:18:11 +00:00
|
|
|
* *Active energy exported AE- [kWh] (when meter is switched to bi-directional counting then
|
2020-01-05 00:06:30 +00:00
|
|
|
* reactive energy imported register contains value of Active energy exported).
|

2020-02-10 14:18:11 +00:00
|
|
|
*
|
|
|
|
* Note about communication settings: The meter must be reconfigured to use baudrate 2400 (or 9600) *without*
|
|
|
|
* parity bit - by default the meter is configured to 9600 8E1
|
|
|
|
* (Frame format: "EVEN 1") . To make those changes, use LE-Config
|
2020-01-23 15:13:25 +00:00
|
|
|
* software (can be found in download tab in product page - link above)
|
