That meter is is manufactured by a few companies under licence from UNI-T and sold under different brand names such as UNI -T ethos kyoritzu . And one or two others they are good little testers not bad quality cheep as chips but perfect for someone just starting out as a starter kit,I recommend them to college students who are training to be electricians and to those who can’t yet afford to buy the big brands like fluke or megger and kewtech I have one that I keep as a backup for my kewtech is sent away for calibration all though mine is a continuity/ insulation resistance tester.
By using the trip button we can know whether the trip mechanism is OK or not. We don't know the trip time which is most important parameter to avoid electrocution. th-cam.com/video/mbjl7s9vMuM/w-d-xo.html
Some time ELCB get tripped and some time current not get increased after 20 mA for 100 mAmp setting and 60 mA for 300mAmp setting. Transformer N earthing and Earthing has been also verified but problem is not resolved
As per IEC standards at 1x RCCB should trip below 300msecs and at 5x it should trip below 40msecs and at 1/2 x it should not trip. Hope this clears your doubts.
The ramp test tells you the trip current in this case it was 24 milliamperes and the trip time was 13 milliseconds.

Board is uni-t 582+
@@30mAkills yes they come out of the UNI-T facility
Sir we can check through test button right . Why we are testing with kit .. what was the importance of this .. could you please explian

Sir iam felix from ooty...rcd available a sir please rate and details and rccb and rcd different sir
RCCB and RCD are same. About rate enquire in electrical shops.
Some time ELCB get tripped and some time current not get increased after 20 mA for 100 mAmp setting and 60 mA for 300mAmp setting.
Transformer N earthing and Earthing has been also verified but problem is not resolved
Remove from circuit and do a bench test and post the result. Using adjustable type is not advisable.
@@30mAkills thanks for prompt response
We are using Gtech make EL1812
Will appreciate if you guide us on bench test
I think Gtech is brand name of Mitarvi
What is the use of other options?X5,x1

@@30mAkills yes sir cleared..Thank u so much
