Answer This Question

You can measure the the voltage of all of the batteries that you named to 3 places behind the decimal point. A fresh 1.5V battery may display as 1.666 VDC, etc. The meter is also capable of reading Voltages down into the mV region.

    Answer This Question

    This meter is capable of displaying the current Voltage condition of an automotive battery but not its state of charge. A battery load tester or analyzer will place a load on the battery under test, yielding a grade and the resultant Cold Cranking Amps.

      Does this detect underground cables and electrical wiring

      Answer This Question

      A multimeter cannot be used to detect the direction of underground cables or hidden wires in walls. It can only measure parameters such as voltage, current, and resistance on exposed and safe-to-touch conductors.

          Very pleased
          I’m very pleased with this digital multimeter. The auto-ranging feature makes it simple to use without having to constantly adjust settings, and the True RMS capability gives me confidence that my readings are accurate. The screen is bright, clear, and easy to read, and I really like that it has a backlight for working in low light areas.It feels sturdy in the hand, and the controls are straightforward enough for beginners while still offering the functions needed for more advanced electrical work. Response time is quick, and switching between settings is smooth.Overall, this is a dependable and user friendly multimeter that works great for both home and work projects.I think it’s an excellent tool and definitely worth recommending.

          Bright and Easy to Read
          The Commercial Electric slim auto-ranging multimeter is a lightweight and accurate multimeter. I compared the voltage and resistance to my old bulky meter and the readings were the same. This meter also comes with a temperature setting and probe. Compared to my thermostat, one showed 77 and the other 76. I actually believe the meter over my thermostat. The meter also comes with a protective case, leads and an instruction booklet that is very detailed. The display is bright and the numbers are large making it easy to read. And, the back has a kickstand allowing you to position it to a comfortable angle. Using this around the house is much more convenient than my bulky old meter.

            A Handy Budget Friendly Multimeter
            It’s been a while since I’ve used a multi-meter. In such, this review will be from the perspective of a novice. The primary reason I got this multi-meter was to test batteries and continuity of cables and such. This kit includes the multimeter, manual, storage case, two test leads, a k-type thermocouple, and disposable batteries to power the device. My first impressions are as follows… The multimeter feels sturdy in the hands due to its rubberized exterior. Although, the backside is made of mostly plastic, so it may slip if placed on an angled surface. It has an adjustable stand that allows it to be positioned upright. The text in the manual is quite small, and it was printed in grayscale that may cause confusion. For example, when the manual refers to the “red” test lead, it appears white. It should be printed in color with larger text. This is a takeaway, but by no means a deal breaker. When I first tried the multimeter, it didn’t appear to respond. It turned out that I had to firmly press the plugs into the jacks more than I anticipated. After doing this, the device functioned perfectly. One feature I really like is that the input jacks light up based on your selection. This prevents confusion. The display has a backlight that can be toggled on and off. There's also a light sensor that activates the backlight automatically in low-light conditions. It has an auto-ranging feature. I found this helpful as it allows for minimal intervention so that you get what you want quickly. The “Hold” button allows you to freeze the display. This could be helpful if you need to jot down notes. The numbers displayed are large and easy to read. The multimeter emits an audible tone when continuity has been detected. It also emits an audible tone when you switch between the various modes. It includes fuse protection for added safety. The test leads come with caps that make it easier to take measurements in various situations. It has an auto power-off feature when left idle, which helps conserve battery life. It can measure temperature using the provided K-type thermocouple. Using this multimeter, I was able to determine which batteries needed recharging by measuring their voltage. It worked perfectly for this purpose. I’ve only had it for a few days, but I’m confident I’ll find more uses for it. All things considered, I really like this multimeter for its robust construction, ease of use, simplicity, accuracy and well thought out features. I would definitely recommend it, especially for anyone looking for a reliable tool for basic testing and troubleshooting.

            Product came looking very promising also with good instructions and manual.. BUT when diving into it you might have a need for a clearer manual. Came with two batteries of unknown brand. All in all product operate well as far as DC and AC Too complex regarding the use of AC though.. not for the average folk.

            Decent multimeter for the price. I might purchase a second as a back. On the back it has a nice little tilt option.
