Basic function: DC Voltage: 200mV/2V/20V/200V/1000V AC Voltage: 200mV/2V/20V/200V/750V DC Current: 200uA/2000uA/20mA/200mA/10A AC Current: 200uA/2000uA/20mA/200mA/10A Resistance: 200Ω/2kΩ/20kΩ/200kΩ/2mΩ/20mΩ Capacitance: 20nF/200nF/2uF/20uF/200uF/2000uF Temperature: -20 -1000℃/-4 -1832F Frequency: 10Hz-20MHz Duty Cycle: 0.1%-99% Special function: Continuity Buzzer, Diode Test, Continuity Test, NCV, True RMS Measurement, Average Measurement, Date Hold, Peak Hold, LCD Backlight, Low Battery Tips, Auto Power Off... Working environment: (0 ~ 40)C, relative humidity 2v drop?). Quite a few meters fail to handle LED testing as they should, so not an uncommon deficiency. Measurement of regular diodes seems to work fine, and produces accurate readings. . Bar Graph - as near as I could tell, the bar graph as implemented on this meter merely reflects the current digital numeric readout. It does not provide the kind of separate quick-reaction display that one sees on more costly meters. Too bad, since this negates most of the usefulness of the bar graph and it becomes merely decorative. . Peak - peak min/max readings seem to be available *only* for AC voltage readings, not the broader min/max capabilities found on pricier meters. . Backlight - works well, but a the backlight LED produces a pronounced uneven lighting on the left side (see photo). Doesn’t bother me much, but some could find this annoying. . Like many Chinese meters, this one beeps every time you turn the selection switch to a new setting: Annoying. . No warnings when the test lead is accidentally left in the10A socket during non-current testing. I took the meter apart and noted that the input protection features are limited, but perhaps a little better-than-average for this price class. The sockets are the usual stamped pot-metal-looking affairs, but the board includes what appear to be decent-sized HRC fuses. The 10M-ohm current limiting resistance is provided by a set of four MELF-type 2.5M resistors. No MOVs to be seen, but but there is a lone PTC. No circuit board cutouts, or other physical shielding, but overall looks perhaps a bit better than the usual cheap-meter average. It claims cat IV 600v rating but I’d hesitate to trust that, and plan to use it only with voltages less inclined to rock my world. See photo... So, not perfect, and not high-end meter quality and features, but still a better-than-average set of capabilities for the price. Should be excellent for general around-the-house tasks, hobbyist use, or as a spare/truck meter. ## Features - Digital Multimeter is a 20000 counts with 4 1/2 auto range digital instrument, which has stable performance, reliability and high precision. - About 15 seconds delay backlight, high pressure alarm and overload protection.

It has wireless voltage alert if you feel uncomfortable sticking leads into an outlet. Just hold the meter within a few inches of an outlet, power cord, appliance, etc and it will beep if there's live voltage. **Q: How do you measure the voltage in a tire as show in the display?** A: That pic with the tire is probably from step-up multimeter model which has temperature measurement feature with thermo-sensor placed at the end of wire connected to multimeter, so pic shows how to measure temperature of hot tire. But this multimeter does not have that temperature feature (that model cost about 25$). **Q: Ranges are 600 mv to 750V and 1000V, Will it measure voltages below 600mv?** A: It will measure down to 0.01mV in both - AC and DC modes, thou manual says - 0.1mV. **Q: Does anyone know where to get a better user manual? The one that came with the unit is translated English and parts of it are unclear.** A: Download the 18+ manual from the Fluke website. This is a cheaper knockoff of the Fluke 18+ (wish I'd bought that instead - they actually support their products) but quite similar, so the Fluke manual is some help. At https://dam-assets.fluke.com/s3fs-public/151718__umeng0000.pdf Or if Amazon removes the above link in a display of customer hostility: flukedotcom then go to support then click manuals then search for 18+. You can download the pdf. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very capable product *by K***. on February 9, 2024* This is an amazing product for the money. It is easy to use if one reads the instructions (which are very well written and easy to follow). Superior accuracy! Great piece of technology in a nice package. ### ⭐⭐⭐⭐ Excellent value for price, good overall accuracy *by D***S on November 1, 2020* I like multimeters and wondered how good a 20000 count $38 meter could be. Well... pretty good!... considering the low price. In a completely unfair test, I compared it to Fluke 289 and Fluke 87V multimeters (which I know to be very accurate). My observations: The Good: . DC Voltage tests (2.5v to 10v) - dead on, very accurate . AC Voltage tests (at household 120V levels) - accurate, within spec . DC current tests - accurate, well within 1% . Continuity tests - quite fast, better than average for a low cost meter . Resistance tests - accurate, well within 1% . Capacitance tests - within spec; the usual 3% - 5% accuracy . NCV - Non Contact Voltage sensor, nice to have, works well. . 20000 count, nice to have. Side effect is that some readings can take a bit longer to settle. . Build Quality - seems better than average for a low-cost Chinese meter. While it does not have the the same heft and quality feel as a Fluke or Brymen, it *does* have an actual removable boot/holster (see photo), a crisp precise selection dial, and decent quality test leads. But like most other inexpensive meters, it does feel somewhat light and plastic-y. . Display is large and readable, sharp and crisp. The secondary readout is nice, but only active during AC voltage tests. The Less Good: . Diode tests - within spec; will light all LEDs but will only read voltage drop for red/yellow LEDs, not green/blue/white LEDs (i.e. anything > 2v drop?). Quite a few meters fail to handle LED testing as they should, so not an uncommon deficiency. Measurement of regular diodes seems to work fine, and produces accurate readings. . Bar Graph - as near as I could tell, the bar graph as implemented on this meter merely reflects the current digital numeric readout. It does not provide the kind of separate quick-reaction display that one sees on more costly meters. Too bad, since this negates most of the usefulness of the bar graph and it becomes merely decorative. . Peak - peak min/max readings seem to be available *only* for AC voltage readings, not the broader min/max capabilities found on pricier meters. . Backlight - works well, but a the backlight LED produces a pronounced uneven lighting on the left side (see photo). Doesn’t bother me much, but some could find this annoying. . Like many Chinese meters, this one beeps every time you turn the selection switch to a new setting: Annoying. . No warnings when the test lead is accidentally left in the10A socket during non-current testing. I took the meter apart and noted that the input protection features are limited, but perhaps a little better-than-average for this price class.

So, not perfect, and not high-end meter quality and features, but still a better-than-average set of capabilities for the price. Should be excellent for general around-the-house tasks, hobbyist use, or as a spare/truck meter. ### ⭐⭐⭐⭐⭐ Very nice set and high-quality Multimeter A+ *by J***S on March 4, 2025* Look out Fluke you have a great made multimeter competitor at a much better price point. Cant go wrong with this purchase.
