    The device is excellent. I bought it on recommendation, I never regret it. Works from two AA elements. All that was before work from the Crown. Now there is an extra crown. The thermocouple up to 100 degrees shows exactly, did not measure further. Settings are many, suitable for anyone, for home even a lot of functions, a good professional device. Sorry the wires in the bag do not moisture, this is a minus of course, but very immaterial.

    A***v –

  32. A***v –

  49. V***M –

    Small pocket multimeter with inverter screen. The readability of the screen is higher than usual. According to the call, it’s a little slow, the video on the network confirms it, but there is a difference from all other multimeters. The sound at the call brakes, but on the screen the scale disappears instantly! So, if necessary, you can use not a food, but a scale. Not the most convenient replacement, but the instant response to the call. The scale reacts even to the contact tree!

    A***a –

  99. S***v –

    Great device. The voltmeter is accurate. Measuring the capacity of 10000 UF accurate and the measurement time is fast, steam… three seconds. I was worried about the flashing of light diodes, so during the test, the voltage at the output of 3,25V is more than enough (there were two batteries of 1,4 V). The viewing angles are good, although in bright light a little pale. For 1560 rubles. Economy equipment, very good. The duration of work from batteries did not have time to check yet.

    S***v –

  100. M***h –

    The product corresponds to the description. Delivery is fast. Packing slightly wrinkled but nothing damaged. Efficiency has not yet checked, as I’m waiting for a parcel with USB batteries Sorbo. I ordered specially for this multimeter, because it has an inverted screen, which means eating will be more, but in the sun and in the dark everything is clearly visible. In it would still measure inductance to add. store and shop recommend. Thank you!!!

    A good multimeter, probes from the cheapest kit are not as convenient as I would like, but measures with sufficient accuracy for a radio amateur, the backlight of the screen helps to work even in the darkest shield. Measurements are conducted quickly, about a couple of seconds. Delivery to the Nizhny Novgorod region. Took 15 days. For their money a very useful device.

    All functions work. Everything determines exactly, except the capacity and voltage of true-RMS at frequencies above 600Hz. With increasing frequency, the error is increasing. The frequency itself determines exactly to Hertz. Frequencies above 2 megahertz determine in MV mode.

    The multimeter received, the appearance is chic, everything works, pleased with the measurement of low-ohm resistors to the hundredth of the ohm (before pressing rel, to compensate for the resistance of wires and probes). The device quickly makes about 3 measurements per second, the accuracy is also good. Relatively long only measured large capacity (several thousand microfarad) capacitors, but this is normal, laid in the principle of charging the capacitor. The thermometer measures the same well. Also need two AA batteries (not included). I’m happy, I have several different devices, there is something to compare with. Seller thanks!

    The multimeter came quickly, but without batteries and with a frill strap on a hard case. So the product is satisfied, there is a small delay when calling (not critical)
