Questions & Answers
Why are y'all putting answers to questions about the MM420 under the "questions" section for the MM720. It seems like customers are being misled, given vague information, and/or misdirected. Why is there no mention of battery count/type, or warranty.
Dear Valued Home Depot Customer, We have reached out to the manufacturer and their Answer is, Thank you for your feedback. The question you referenced was submitted under the MM720 product page but was specifically about the MM420, so the response addressed the product the customer was asking about. Regarding the MM720, the battery and warranty information are available on the product details page. The MM720 operates on two AAA batteries (included) and is backed by a Limited Lifetime Warranty. If you have any additional questions about the MM720, please let us know or contact Klein Tools Customer Service at customerservice@kleintools.com for further assistance.
Does this allow use of a K-Type temp probe (like the one pictures) or does it use something different? If so does it come with the temperature probe or do you need to purchase that separately?
Klein Tools Cat. No. MM720, Digital Multimeter, TRMS Auto-Ranging, 1000V, Temp, Low Impedance, uses a K-type thermocouple for temperature measurements. The meter includes a K-type thermocouple with adapter, so a temperature probe is included and does not need to be purchased separately. The MM720 can measure temperatures from -40° to 1832°F
Does this multimeter take tempature readings?
Yes, the Klein Tools CAT No. MM420 Digital Multimeter, TRMS Auto-Ranging, 600V, Temp, takes temperature readings via the K-type thermocouple.
Does the MM720 have the capability to display 10 volt range with resolution 0.001?
The Klein Tools Cat. No. MM720 1000-Volt Digital Multi-Meter has a 6V range with 0.001 resolution; after 6V it jumps to 60V with lower resolution.
Can this be used on cars, trucks and heavy duty vehicles
None of our clamp/multimeters measure parasitic draw, dwell time, RPM, or pulse width, but we are working on one that does in the future! If you do not need those measurements - in theory, yes, the Klein Tools MM720 Digital Multimeter can be used for automotive work.
will MM420 measure capacitance down to 1 microfared?
Yes. For the full meter specs and measurement ranges please see the Instructions/Assembly document under Additional Resources From the Manufacturer
will this detect irrigation valves
Klein Tools MM420 Multimeter is an auto-ranging, true root mean square (TRMS) multimeter that measures AC/DC voltage, AC/DC current, and resistance. It can also measure temperature, capacitance, frequency, duty-cycle, and test diodes and continuity.
Does this have an NVC mode function?
The Multimeter does not feature a non-contact voltage testing function
