How to calculate CurrentGainCT# #18

Closed lanhtudongxanh closed 5 years ago

lanhtudongxanh commented 5 years ago

Hi there, In the energy_meter.h file, I see below: / 25498 - SCT-013-000 100A/50mA 39473 - SCT-016 120A/40mA 46539 - Magnalab 100A /

define CURRENT_GAIN_CT1 39473

define CURRENT_GAIN_CT2 39473

but I use the DLXQ 20 100A/100mA current sensor. So I don't understand how to you calculate CURRENT_GAIN_CT# for it. Please help me, calculate the CURRENT_GAIN_CT for my current sensor. Thank you!

Hello! I haven't had an opportunity to test this CT myself, so I don't have a calibration value. I can estimate the value to be around 13000, assuming it has a 100mA output.

Please see the calibration procedure here to get a more accurate calibration value: https://github.com/CircuitSetup/Split-Single-Phase-Energy-Meter#calibration

Hi, Perhaps a short write up I did https://github.com/BitKnitting/FitHome/wiki/EnergyMonitorFirmware#calibration will help please let me know if the info can be improved (assuming it was helpful at all).
