Questions & Answers

Can you check capacitors?
ByApr 14, 2026
1 Answer | 
Answer This Question

The unit does not have a dedicated capacitance test mode, however capacitance can be checked using the resistance/ohms measurement mode. To test a capacitor with a resistance (Ohms) setting on a multimeter: First, discharge the capacitor safely. Set the multimeter to a high resistance range (or), connect the probes, and look for low resistance that gradually rises to infinity (or OL).

        What is the MINIMUM AC voltage the meter will read? 12 volts AC? 24 volts AC?
        ByMay 15, 2025
        2 Answers | 
        Answer This Question

        This is only accurate to 0.001 volts if your total voltage is under two. I just received lithium batteries from China that have a voltage of 3.31, and I have to use the 20 volt setting which reduces the accuracy to .01

        By|Feb 7, 2026

          Dear Customer, the minimum AC voltage the meter can read is 0.001 volt AC.

              Why does the word bad come across screen on commercial electric multi meter
              ByJan 6, 2025
              1 Answer | 
              Answer This Question

              Dear Customer, the "BAD" word is for the battery status indication when it switches to battery posistion and test battery. If the battery is in bad status, it will show " BAD" to indicate the battery need to be replaced.

                    The meter was overpriced for its functionality. It was delivered the very next day as promised! I do love the free delivery of Home Depot credit card service.

                    Great value, couldn't be more pleased
                    A great value for a multimeter. Sure there are some more fancy and more expensive multimeters on the market but for a hobbyist and home DIYer this is fantastic. For AC, DC, and continuity checking its great. It has much more functionality than I have the ability to comprehend but its there if i need it. The construction of it robust and the display is big bright and easy to ready even in full sun. I highly recommend this!

                    Good multimeter
                    This is a nice standard manual multi-meter. It is a precise machine and serves a lot of functions, reading voltages from computers to batteries. I most often use a multi-meter when diagnosing car or home electric issues and testing batteries. I found this multi meter accurate and easy to use. It came with two AAA batteries to get it going and a manual. This multimeter is made in China.

                    Good product for home use.
                    I used this unit to measure the AC voltage on a wall outlet and it was accurate. I used it to measure the DC voltage on a 9 V battery and it worked fine. It also measures resistance and current. It comes with two AA batteries and the leads you need. The case is very tough and looks like it could easily withstand a fall. This is a good product. The only drawback is the manual ranging. The auto-ranging ones are a lot more expensive I am sure.

                    Nice capable meter
                    This meter does everything I need and more. I am a contractor who sometimes comes across some minor electrical things that I need to address. I was looking for a capable meter that wouldn’t totally break the bank. I am very pleased with this meter’s performance. I have used it around my house, garage and even on my vehicle since it does DC as well. The screen is easy to read even in direct sunlight, can also be backlit by holding the light button. Thumb dial is easy and precise and the leads have a nice length and clip into the body of the meter securely. The only thing I wish it had was a carrying case or bag, so that it doesn’t get damaged in my electrical bag or truck. I would 100% recommend it.

                    Manual Multimeter
                    This manual digital multimeter by Commercial Electric is a very good multimeter for its type. It will test up to 600V AC/DC and 10A AC/DC. True RMS technology takes very accurate measurements. Multimeter features backlight for easy reading at dark/low light situations. It uses two AA batteries which are easily available and simple to replace. Includes test leads.

                    Commercial Electric #DMM-8301
                    The Commercial Electric #DMM-8301 Multimeter has several features which set it apart from my previous multimeters. First of all, the rubberized grip on the sides make it much easier to grip which is important when testing around higher voltages. The stand on the back is certainly handy when doing bench work. The lighted display area is large and easy to read. Two fuses are in the battery compartment and the unit uses 2 AAA batteries which were included. Should be a solid piece of equipment for a DIY'er.

                    Great Multimeter
                    This is a very handy portable volt meter that is easy to use and read. One of the best features is the backlit display. It is easy to read in bright light or a darkened access panel. I also like the the "holders" on the back of the meter that help store it where the leads are in one place. There is a setting where it will "beep" when testing continuity - no need to watch the ohm meter. It also has a pop out stand if you are working say on a workbench with it. All in all a very good meter that appears ro be well built and is easy to use.

                    Commercial Electric 600V True RMS Manual-ranging Digital Multimeter
                    I recently ordered and received the Commercial Electric 600V True RMS Manual-ranging Digital Multimeter. I have only begun to use this instrument, but so far it has responded to all common uses flawlessly. By common uses I am referring to AC/DC voltage, continuity and amperage measurements. I find a good digital multimeter to be invaluable for use around the house, on my automobile and when we are camping in our RV. This particular model is a manually operated unit which means that the user must choose the mode in which it is to be used. It comes in a bright green impact resistant case and includes positive and negative leads and two AAA batteries which are required to operate the unit. As I mentioned, I tested this unit, and it works as well as my FLUKE multimeter. I have included several pictures below. Based upon my limited use thus far, I would recommend this multimeter.

                    Nice Well Built Accurate Digital Multimeter
                    I use my new Commercial Electric digital multimeter almost every day now and find it to be very accurate and reliable. It has thicker rubber type bumpers around the outer edge of the front face to help protect it from accidental dropping or potential damage. It also has replaceable fuses in the battery compartment in case it gets overloaded. I use this a lot in my diagnosis of automotive electrical problems and household electrical problems. It measures DC voltage, AC voltage, DC current, Resistance and Continuity. It also has auto off function, a Data hold function and a backlight function. It also has an audible function for measuring continuity. I'm very happy with this multimeter and hope to get years of service from it. I highly recommend this to others.
