In my household completely absent screwdriver indicator for a long time. Just небыло necessary, and tseshka always in the table. " However, walking in the supermarket Castorama saw on display in this electric tester from the manufacturer RESANTA , and could not resist the low price and interesting view of the screwdriver-probe. Of course, first I had changed my mind, because even the packaging screamed "Dude, this Galimov China !!!", but then I thought, have decided to take, resigned to the loss of the screwdriver after a short time.
In general, we have become accustomed, that the indicator screwdriver - Tester, it's just a screwdriver with a light bulb, which in the presence of voltage in the measured spot just glows. However, I am interested in the screen is small, digital, who said that they will show some figures, and that is simply the achievement of space technology, not less! 
But as usual everything was simpler. That is, no specific figures stress you can not see, simply because the display is static, and all the numbers that they are changing, tough stand on the screen They just light up, respectively, for voltage measurement. Probably still are digital testers, which show a specific voltage, but I think they have a price tag higher than that chinaparata. Manual operation of the tester said that the e-tester can be measured and the presence of DC, and to check the status of chemical sources of electricity such as AA , AAA , C, D. However, either I've already burned by measuring the 220:), or I do not understand how to measure, but nothing he did not show it.
The electric tester has a display layout on the following threshold voltage of 12 V, 36 V, 55 V, 110 V, 220 V,
Вобщем, the device is clearly better than a standard screwdriver tester with light bulb.
Batteries not mereet, because the minimum threshold of 12 V
Simon, I'm so some thought. We went to check on the car battery is really shows that there is 12V
