12 best digital dm tools
Digital DM (Digital Multimeter) tools are essential devices used in various fields, especially in electrical work and electronics. They are a type of tester or measurement tool commonly found in the electrical and tools home improvement categories. Here are key aspects of digital DM tools:
Functionality: Digital multimeters are versatile tools that measure multiple electrical properties, including voltage, current, resistance, capacitance, frequency, and continuity. They are used to troubleshoot, test, and maintain electrical circuits and components.
Display: These tools have a digital display that provides precise numerical readouts of the measured values. The digital format is easier to read and interpret compared to analog multimeters.
Measurement Ranges: Digital multimeters offer a wide range of measurement options and scales, allowing users to measure both small and large values accurately. The range can be manually selected or set to auto-range mode where the meter selects the appropriate range automatically.
Accuracy: Digital multimeters are known for their high accuracy, making them suitable for tasks that require precise measurements. The accuracy is usually specified in terms of a percentage of the reading.
Functions: They typically include various functions like voltage measurement (AC and DC), current measurement (AC and DC), resistance measurement, continuity testing (to check if a circuit is complete), capacitance measurement, and frequency measurement.
Safety Features: Many digital multimeters come with safety features such as overload protection, fuse protection, and input jacks designed to prevent incorrect connections that could damage the meter or the circuit being tested.
Auto-Shutdown: To conserve battery life, digital multimeters often have an auto-shutdown feature that turns off the device after a period of inactivity.
Data Hold and Recording: Some models have a data hold function that freezes the displayed value, making it easier to record readings. More advanced models may allow users to record and store measurements for later analysis.
Backlight: A built-in backlight on the display is a helpful feature, especially when working in low-light conditions or tight spaces.
Portability: Digital multimeters are typically handheld and portable, making them convenient for use in various locations and situations.
Battery Powered: They are usually powered by batteries, making them suitable for fieldwork where access to electrical outlets may be limited.
Calibration: Periodic calibration may be required to ensure the accuracy of the measurements.Some models have a built-in calibration function.
Digital multimeters are indispensable tools for electricians, electronics technicians, hobbyists, and anyone working with electrical systems or electronic components. They provide accurate measurements and valuable information for diagnosing electrical issues, verifying circuit performance, and ensuring electrical safety. Their ease of use and versatility make them a must-have tool in the field of electrical work and home improvement.

User questions & answers
Question: | Im a service technician out in the field. have iphone6. alot of times i don’t get signal for my iphone. will this be an issue to connect to its wifi |
Answer: | Hi Survivorman29, The 200 footers come shrink-wrapped on a tube and measure 6.5" x 3.5" (Cylindrical.) All the Best, Bill... TOUGH-GRID |
Question: | Do you have to take photos/videos or can you just use it to view without capturing images |
Answer: | Thanks for your question, Seth. Our 1000 footers may come in up to two non-spliced sections, but the shortest length of a section would be 300 feet. Take Good Care, Adam... TOUGH-GRID |
Question: | Will this work with a Kindle Fire Tablet |
Answer: | Per the description: Cord diameter measures 3/16" (+/- 1/32"). |
Question: | Is there a way to watch what is recorded in slow motion |
Answer: | Hi Craig, Yes... but only as a special order so we make sure and get it right. There is sort of a long and complicated answer for this question but give me a call if you really want a continuous 1000 footer. That said; most of our 1000 footers are continuous and the shortest section is never less than 300Ft. and IF there are 2 sections, they are NEVER spliced together. All our other sizes are Guaranteed Continuous. We find it to be very rare that someone actually needs 1000Ft. continuous but do our best to accommodate them as needed. If we were to guarantee all 1000 footers as continuous it would be very expensive on our end and to our customers and we just don't want to do that to folks. All the Best, Bill...

User questions & answers
Question: | What size is the case inside |
Answer: | I don't quite understand the question. The circuit tester will work on 120 volt outlets. Some dryers have 240 volt plugs and the circuit tester will no plug into the outlet. However, the VOM (multimeter) will work just fine on either a 120 or 240 outlet. The non-contact voltage tester will work on either outlet voltage design. |
Question: | are their alligator clips available for the test cable ends |
Answer: | If my Fluke had not been stolen, I could check it out. I don't know. |
Question: | I assume the receptacle tester can be used on regular/non gfci receptacles too |
Answer: | It does come with leads but not sure if silicone or PVC. I'm happy with the one I got. |
Question: | Will this work on dryer outlets |
Answer: | Get an XXL. I usually wear an XL and ordered one. It was too snug. I then ordered a XXL which fit better. The sleeves are a bit long but I can live with that, fits good in the body. |
