Hola, compre el modelo MH12 hace poco por ALIEXPRESS, un equipo muy económico para todo lo que hace. Medidas confiables. Algo que no entiendo, es que dice que mide hasta 10G.....pero en realidad mide hasta 20G 🤔... Lo único que no me gustaba, era que no traía una entrada externa para alimentar con 12vdc.... Entonces le coloque una, y quedo tan bien que parece original 🙂..... Además incluí en paralelo a la entrada externa de 12v un led, para que al introducir el plug de 12v encienda y avise que el equipo ya tiene alimentación en la entrada. Con esta modificación no gasto en baterías, solo las utilizo cuando no existe un toma corriente cerca 👍. Otra cosa, por casualidad encendí el equipo manteniendo presionada una tecla ( no recuerdo cual ) pero al encender, en la pantalla decía CALIBRACION , osea que estos equipos se pueden calibrar.... pero he buscado en internet y no aparece el procedimiento, si alguien sabe, por favor compartan 👍👍

You know, I used to be pro-duracell coppertops, never used to have any issues with them at all. Then a few years back, nothing but problems with them. I've now switched to Energizer Max / Energizer Max Plus, and the Energizer Lithium batteries.

NZS/AS3000 has some specifications to be met by insulation testers so it would be useful to know if that meter actually complies. Some do not so are useless for compliance testing. On the 500 vdc range the meter should maintain the nominal open circuit voltage within +20% and -10% across a 1M ohm test resistor and similarly on the 1000 vdc range maintain the nominal open circuit voltage with a 10 megohm test resistor.

@@TheDefpom There are potentially more issues with this meter. The supplied leads appear to be just regular multimeter leads probably claimed to be good for 1000 volts so completely unfit for purpose as a 2.5 kV insulation tester. Also, the regulatory requirement in NZ and Au and probably many other counties is for the insulation resistance to be 1 M ohm or higher for regular 230/400 volt installations. As you showed, this meter appears incapable of displaying down to 1 M ohm. There is a good reason why proper insulation testers from reputable brands like Megger, AVO, Fluke etc are far more expensive - they pay attention to guaranteeing to meet international standards and assuring safety.

Did I seen correctly - You tried to measure Riso of cable 300/300V with test voltage of 2500V? You shouldnt use more than 500V.

You will burn the insulation if you use unreasonably high voltage. During testing, it is inappropriate to develop minor defects that do not affect normal operation into dangerous ones, which, reducing the electrical strength, may appear during operation.

I don't understand, the probes that came with the meter are rated at 1,000 volts. Should they have a higher rating than the tester's output? Glad you are slowly getting better. 🍻

Гарантированное напряжения пробоя изоляции каждого щупа больше 1000V. При измерении сопротивления изоляции электроустановки следует размещать провода щупов так, чтобы они не касались друг друга, корпуса оборудования или человека. В этом случае, думаю, всё будет хорошо.

@@bblod4896 The guaranteed insulation breakdown voltage of each probe is greater than 1000V. When measuring the insulation resistance of an electrical installation, the probe wires should be placed so that they do not touch each other, the equipment body or a person. In this case, I think everything will be fine.

The leads are rated for 1000V at 10 Amps, these output upto 2,500V at far below 10 Amps, around 3mA typically.

The E&V Bakelite Megger will still be working when the Aneng has long since failed and gone out with the trash. I was lucky enough to find a Bakelite Evershed & Vignoles Megger in pristine condition, really well looked after, even the leather case is like new. Paid around £30 on eBay but worth every penny. In rougher condition you can sometimes get one for around 15-20.
