This page compares four digital multimeters from the research set, checked on 2026-10-11. The keyword names a meter, and the four listings in the set that match it are an AstroAI 2000 count multimeter, an LJPXHHU 2000 count multimeter, a ZMIWNIED FS899L 6000 count True RMS meter, and an ANENG SZ301 multimeter. The research set also held clamp meters and kWh meters, which are covered on other pages and are not compared here. No listing in the set is an SC480 model, so this page covers the multimeter product type instead.

Multimeter specifications are easy to misread because each function has its own range, resolution, and accuracy line. The sections below quote each listing’s stated figures with the function they belong to, and they show conflicting figures side by side where a listing contradicts itself.

Quick answer

The ANENG listing is the only one of the four that gives a full accuracy line for each function in its specification table. The ZMIWNIED listing has the highest stated count at 6000 and the only stated CAT III 1000V rating in the set. The AstroAI listing gives the most detailed fuse and DC voltage range data, but its own bullets and tables disagree on sampling speed and battery type. The LJPXHHU listing states the most general set of functions and gives the fewest range figures in the fields reviewed.

Use the table to match the function you need, then confirm the range on the product page before buying.

AstroAI Digital Multimeter Tester 2000 Counts

View the AstroAI multimeter on Amazon

The AstroAI listing, model AM33D, states a 2000 count digital multimeter. Its specification table gives DC voltage ranges of 200mV, 2V, 20V, 200V, and 600V, with a stated accuracy of plus or minus 0.5 percent plus 3 digits on the DC voltage line. AC voltage is given as 200V and 600V with a stated accuracy of plus or minus 0.8 percent plus 5 digits. DC current has ranges of 200 microamps, 200 milliamps, and 10 amps, and resistance runs from 200 ohms to 20 megaohms. The fuse data lists 250 mA at 250 V for the milliamp input and 10 A at 250 V for the 10 amp input. The listing states CAT II 600 V and CAT III 300 V, a 0 to 40 degree Celsius working range, and a weight of 0.15 kg. Its own bullets say the meter does not read AC current in every case and does not read AC voltage below 100mV, and that the sampling speed is 2 times per second, while the specification table says 3 times per second.

LJPXHHU XL830L Digital Multimeter

View the LJPXHHU XL830L on Amazon

The LJPXHHU listing, model XL830L, states a 2000 count multimeter with AC and DC voltage, DC current, resistance, continuity, and diode functions. It also names battery testing, which is listed as a function in its bullets. The display is described as a 2.7 inch backlit LCD with a data hold function. The item weighs 166 g and measures 5.51 x 2.56 x 1.18 inches. The bullets describe overload protection, and they name household and automotive troubleshooting as uses. The fields reviewed for this page do not give the voltage or current ranges, so the listing cannot be placed on a range scale with the other three. Its weight and item dimensions are the only size figures in the fields reviewed.

ZMIWNIED FS899L Digital Multimeter

View the ZMIWNIED FS899L on Amazon

The ZMIWNIED listing states a 6000 count True RMS auto-ranging multimeter. Its bullets list AC and DC voltage, current, resistance, and capacitance, and they mention continuity, frequency, and live-wire detection. The specification table gives CAT III 1000V and CAT IV 600V. The display is a 4.8 inch color screen with a built-in flashlight and a Data Hold function. The listing says it charges over USB-C and gives a fast 2-hour charge. The part number is FS899L-1, and the package includes two alligator clips and an instruction manual. The range figures for each function are not stated in the fields reviewed, so the accuracy of each function cannot be read off the listing.

ANENG SZ301 Digital Multimeter

View the ANENG SZ301 on Amazon

The ANENG listing is the most complete specification table of the four. It gives a range, a resolution, and an accuracy line for each function. DC voltage runs from 200mV to 600V with a resolution of 0.1mV to 1V and an accuracy of plus or minus 1 percent plus 5. AC voltage runs from 200mV to 600V with an accuracy of plus or minus 2.0 percent plus 10. DC current and AC current each run from 2mA to 10A with an accuracy of plus or minus 2.5 percent plus 5. Resistance runs from 0 ohms to 200 megaohms, and capacitance is listed as 0nF to 2MF. The listing gives a max count of 2000 and an LED screen. Its weight is 155g. The bullets describe AC and DC voltage and current measurement, and they say the display shows settings and modes. One bullet is a generic description of how probes work, and the listing does not add any figure from it.

How we chose

The research set held twelve listings for the broader meter keyword. Four are digital multimeters, and those four are compared here. The other eight are clamp meters, kWh meters, a tape measure, or a Stetzerizer meter, and they are left out of this page. The four comparison picks are chosen by function, not by price or rating, and the page does not use price or rating data. Each figure is taken from the listing fields and bullets in the research file.

Worked example: reading the DC voltage accuracy lines

Take the DC voltage accuracy lines from two listings. The AstroAI listing states plus or minus 0.5 percent plus 3 digits. The ANENG listing states plus or minus 1 percent plus 5 digits. The percentage part is the same kind of figure in both, so for a reading of 10 volts the AstroAI percentage term is 0.05 volts and the ANENG percentage term is 0.1 volts. The digit term is a count of the last displayed digit, so it adds a small amount that depends on the range in use. The two listings therefore differ by roughly double on the percentage part, and by a different digit count, at the same reading.

The worked example shows the limit of the comparison. The ANENG accuracy line gives a figure for every function, but it does not state a per-range resolution in a form that can be matched to the AstroAI ranges. The AstroAI listing gives per-range data for DC voltage, but its two sampling speed statements conflict. Neither listing can be read as complete on its own.

What the listings do not say

The LJPXHHU and ZMIWNIED listings do not give the voltage ranges for each function in the fields reviewed. The LJPXHHU listing names battery testing as a function, but no battery range is stated in the fields reviewed. The ZMIWNIED listing names a 6000 count display, but the count alone does not show the range of any function.

The AstroAI listing gives two different sampling speeds and two different battery descriptions. The table lists 2 x 1.5 V AAA batteries and the included parts list a 9V battery. The ANENG listing gives no fuse rating in the fields reviewed.

FAQ

Which of these multimeters states the most complete accuracy data?

The ANENG SZ301 listing gives a range, a resolution, and an accuracy line for each function in its specification table. The AstroAI listing gives accuracy lines for DC and AC voltage and DC current, and it gives resistance accuracy as well, but its sampling speed conflicts with its own bullets.

Which multimeter in this set has the highest stated count?

The ZMIWNIED FS899L states 6000 counts, which is higher than the 2000 counts stated for the AstroAI, LJPXHHU, and ANENG listings.

Do the listings state CAT ratings?

The AstroAI listing states CAT II 600 V and CAT III 300 V. The ZMIWNIED listing states CAT III 1000V and CAT IV 600V. The LJPXHHU listing says safety standards are met without naming a category, and the ANENG listing does not give a CAT rating in the fields reviewed.

What battery does the AstroAI multimeter need?

The AstroAI specification table lists 2 x 1.5 V AAA batteries as the power. The included components list names a 9V 6F22 battery. The two statements conflict, so the battery requirement should be read on the product page before ordering.

Conclusion

Among these four multimeters, the ANENG listing gives the most complete accuracy table, the ZMIWNIED listing gives the highest count and the only CAT III 1000V rating in the set, and the AstroAI listing gives the most range detail for DC voltage with conflicting sampling and battery figures. The LJPXHHU listing is the least specific on range data. The choice depends on which function, range, and safety rating the job needs, and the listing data is enough to narrow the field but not to rank accuracy in practice.
