Direct Deal 1000V Bm500A 1999M Digital Insulation Resistance Tester Meter Megohmmeter #D6309#

Not a bad small mega-meter bm500a. One of, if not the cheapest in its class, so there are no advanced modes of change, even a voltmeter. It is powered by one 9-volt battery 6F22 (known in the state union as "krona"). Therefore, it is very necessary for its parameters-voltage and internal resistance. The low voltage indicator of the battery on the device turns on when its voltage is reduced below 8,5 v. The consumption current from it when measured back is proportional to the resistance of the measured object and can be calculated according to the OM law based on the efficiency of the voltage converter of the device about about about For example, when measured at 1000 V resistance of 1 Mohm from a 9,0 V battery, the current of 150 Ma is consumed. Also, it seems that the polarity of input nests is mixed: on E (Earth) plus; on L (line) minus the measuring voltage. On those megometers I worked with was the other way around. Took as a compact source of high stress for 714 rubles (coupons) at a catalog price of 1034 rubles.

Product delivered very quickly pure this period covid about 10jrs. The measurements are in accordance, I tested it on electronic R, the voltage also has some Volts ready Holds in hand which makes it very practical. Small negative point the cables with the mini croco pliers not always very practical and fragile.

Simple, cheap insulation tester. I'd recommend getting better probes, the ones provided arn't really suitable for high voltage work. Test voltages measure correctly, too. Certainly can't argue with the price!

It turned out to be a small smartphone. Conveniently lies well in the hand. The output voltage is the same when the short circuit shows zeros. It came in a month.

The device is compact, equipped with two wires with crocodiles and one with a gap. There is no illumination. I did not communicate with the seller.

Great tester! Shows you exactly enough. The wires are not very, thin, the insulation is fragile, but for this money and did not wait for good.

Volts give it away. And there is no resistance to a large nominal at hand. So I do not yet understand whether it is working.

Very good product, meet your function at very good price. Shipping very fast. Recommended 100%

Normal device. For its price-perfectly performs its functions. Krasnoyarsk reached 18 days!.

It is a team for casual use, not for intensive professional use. Good quality-price ratio

Arrived well packaged. Device is as described and works. Thank you and have a nice day.

I recommend the seller. It came quickly. It's whole. Works correctly and clearly.

Does what it’s supposed to do, first leak to the earth diagnosed and repared.

I was surprised to arrive earlier than expected, it works as follows

All as promised. .. Thanks... checked .... the device is working

Great equipment arrived very well packed, did some tests all OK.

looks ok, works correctly when measured by multimeter. A+

Delivered quickly, prdavtsu, operation is not verified

Description is very good. I got it. Thank you.

Very quickly. Good device and correct price.

Good device, fast enough delivery. Thanks!

Fast delivery, the goods meet Description

OK. Today arrived naked right was Gegé

It's delayed but I get there thank you

All perfect and fast delivery, thanks.

According to the product description.

Taxed, more expensive than the fish

Haven't used it yet but looks good

All right. Testing.
