I am very satisfed with GVDA GD169A Digital clamp meter, There are reviews of the GVDA kit on You Tube. There are producing good products and pushing hard for market share.
It was well packaged with a anti tamper sticker on the box. The black zippered carrying case seems more than adequate for the job. It has some spare room. There is a pair of long test leads and a thermocouple on a wire for measuring temperature. There are also instructions of which I was able to assimilate 90% on the first reading. It comes with batteries and needs a small Phillips pozidriv screwdriver to remove the battery case. The screen was a bit of a shock as I am using a 40 year old Maplin precision multimeter. So much information appears! There is a work light. I tested it on the kitchen table in front of me (my wife is away) on the cable running to the extension lead carrying the Ipad charger. Nothing seemed to happen on the mains cable or the cable leading to the Ipad. Hmm - read the instructions and it appears that as there is a forward as well as reverse flow in the composite cable the magnetic fields induced cancel each other out. Obvious when explained. To use the clamp meter the conductors need to be put in the clamp meter separately, perhaps a plug and socket with separate wires between for the electrical tool kit. I bought it for testing and setting up medium size wood working machines on single and three phase. The no contact voltage detector worked at 0.75 m showing low and then moved to high at 0.2 m from the mains wire on the table. I suspect there are a number of wires in the wall nearby. In another position it was not so sensitive. Last time I had this with a tiny tester it was because someone had hammered a picture nail into the live conductor in the wall without knowing it several years previously. It was acting as an aerial and setting off the voltpen at almost 2 metres distance. Overall I am extremely pleased with my purchase. Build quality seems excellent.
