I order a prepaid 3 phase KWhr meter from Huabang Electric Technology Ltd. represented by Jason Huang. I tested the meter on a test bench to check the meter before installing it to where I needed it. During my testing connected to 3 phase supply and fed the program card, the meter switched on, but the out coming of 1 phase, the first on the left was dead, where else the other 2 phase gave me good out coming voltage. I am a qualified engineer and know very well what I`m doing. I reported this situation to Jason Huang and his reply was that I was not operating and installing it well. He even demanded photos of the installation and I supplied, But also insisted that the meter was checked before delivery and I`m doing something wrong and even installing my professional. I even consulted a separate consultant engineer (where he totally agreed with my results) to try persuade Jason, but with no success. I even reported this case to Alibaba assurance policies, but again their bureaucracy leads me nowhere and it cost me twice as much the whole meter cost. The meter`s manual specify that the meter cannot be dismantled or open due guarantee. It seems guarantee never excite with Jason Huang for all the hassle he gave me. This also indicates that the product was never check before delivery.
Since Jason was arrogantly and not ready to solve the problem, I decided to open the meter and diagnose the fault. I found that the coil relay connected to the faulty phase was totally disconnected and even so the other 2 coil relays connection just put in position without soldered.
Although I solve the problem myself, I had also lot of problems programming the insert cards due old software, so I had to scrap the whole project.
SO THAT I DECLARE JASON HUANG OF HUANBANG ELECTRIC LTD. IS A BIG SCAM
