DROK Frequency Electric Voltmeter Multimeter Review

I connected 3 different meters to my 115v home network and saw strange readings on the Drok 6 meter. As you can see in the image above, my BK and Kyoritsu meters read 114V and 115V, or within 1% of the correct value. In contrast, the Drok meter reads less than 96 volts, or 16% below the true value. This goes far beyond the specified accuracy of "1% ± 2 digits" and is therefore inaccurate and unusable for almost any technical purpose. Since power and energy readings are voltage dependent, I…

These DROK color meters are great! Can easily control voltage and current at the same time. Because a current transformer is used, you don't have to worry about the sense resistor overheating. They are great for monitoring a plug-in hybrid charger. This allows you to determine exactly how much current is being drawn and what the input voltage is. If the voltage drops, that's a quick sign that your wires are too thin. The accumulated kWh are just an added bonus. I installed 3 of these in my…

I installed this on a dedicated 240 volt 30 amp circuit to reduce the power draw of an indoor infinity pool to monitor. It seems to measure voltage and current. I'm still checking. But about an hour after the installation was complete, the display began to blank in a very predictable pattern: 88 seconds on, 7 seconds off, repeat. I disabled everything and checked all connections. They are alright. I turned it on and saw the 88/7 scheme. It used to turn on at 60 seconds and off at 7 seconds…

First you need to install it properly. The schematic even says that wrong connection will damage the instruments, although they still work and don't explode (ha). So look at the bad reviews like I did before buying, they seem kinda wrong. Installation tips: Before charging, connect the voltage input wires in parallel with the test circuit. I just hooked up 14/2 15 amp wire line, a load (sprinkler system) and a meter with 3 wires in a wire nut. The meter and connections are housed in a double…

What can I say, I am more than satisfied with this product. Given the low price, I decided to get one. I was a little confused by the color display as I had never seen this style/technology before. I don't know how new it is but I like it. It appears to be an inverted version of a standard calculator LCD, but with a color filter in certain areas and a backlight to give it that look. (if so, this is a winning design). I have attached some photos of what I did with my product; Since I wasn't sure
