KAIWEETS Digital Multimeter TRMS 6000 Counts Voltmeter Auto-Ranging Fast Accurately Measures Voltage Current Amp Resistance Diodes Continuity Duty-Cycle Capacitance Temperature for Automotive

great digital multimeter for a good price, easy to use has noob lights to show where to plug for functions and auto ranging, uses aa batteries so heavy users will probably change more often, but the batteries that came with it are still strong, will swap to lithium aa's. functions are good and readings are accurate.stout little DMM. I even bought all the extra probes for this model

I go to an aviation maintenance school and a multimeter was one of our required tools. Some of the options they listed were hundreds of dollars! This product gets it done at a fraction of the price. The display is nice and easy to read and it works well and has been durable and easy to use

This is to update my previous review. They original one I received was used obviously because it had holes drilled in it! I had a conversation with the seller and they assured me that it was Amazon that sent me a used one and that could not have possibly happened through their distribution.The replacement unit works well. It does meet specifications listed in the manual. The case seems to be of a sufficient quality to make the meter reasonably rugged especially in this price range. The test leads are typical PVC insulation so they're a little stiff and specially in cold weather, but they are functional and what you would expect in this price range so I'm not going to knock them. Optional silicone test leads are available for a few more dollars and I would recommend getting them if you're using this meter for more than hobby or home use. The replacement test leads (not expensive) also come with adapters for various uses and those are handy in many situations even if you are a hobbyist, home tinkerer or a shade tree mechanic. Also the warranty is a plus. 3 years at this price point is unheard of anywhere else. I was impressed enough that I purchased another Kaiweets meter, the peak current inrush reading amp clamp. I was trying to find a model number in the listing but it is the unit that is as of February 25th selling for $89.95. It has also turned out to offer value beyond its price.The meter seems to be rugged and would take a few hits but I wouldn't try throwing it against the wall like you could with a Fluke. Then again you're not paying Fluke prices and if used in the proper setting this meter will last. If you're not going to use a meter for a long time please remove the batteries. Alkaline batteries contrary to some opinion will leak and cleaning that up can go anywhere from being an annoyance to totally destroying the meter. If you're using this in a home setting, hobbyist, shade tree mechanic or light-duty commercial use not involving high energy systems it's a very good value and I think you'll be very happy with it. But as always if you're in an industrial setting and you need cat 3/cat 4 I would go with a proper industrial meter that has had the cat 3/cat 4 rating performed by UL, ETL or in Fluke's case, Fluke's own in-house testing lab. Would you really trust your life in those situations to a product that cost $36? I would hope not.From my previous review:I opened by meter today and it looked good until I turned over the meter to put the batteries in. There are two holes drilled into the kick stand and two holes started but not finished. These are not factory at all and either this was a demo or a used meter recycled as a new unit . Returning for a refund. I purchased a new unit NOT a refurb or return. The box seal shows evidence of being peeled back and replaced.I will not rate accuracy, easy to read, or value for money. I have not looked at any of these. I'm not even bothering with inserting the batteries. If the company will send one out like this, I cannot trust the unit for accuracy nor safety.

I am not an electrician, but am pretty obsessive about accuracy, and I also care about ease of use and readability of the little screens. There are many dozens of digital multimeters (DMMs) available from Amazon, but I have investigated only the DMMs listed below. I will briefly offer an opinion on three DMMs from Kaiweets (the HT208D; the KM100; and the HT118A) and one DMM from Mestek (the DM100C), all purchased from Amazon. In the accompanying pictures, the units are, from left to right, the Kaiweets HT208D, the Kaiweets KM100, the Kaiweets HT118A and the Mestek DM100C.SUMMARY of my opinions. Overall, the STATED accuracies of the Mestek DM100C are usually higher than the stated accuracies of the three Kaiweets DMMs I looked at here – and the accuracies of the little Kaiweets KM100 are the worst. I feel that the Kaiweets HT208D is the easiest to use, while the Mestek DM100C is the most challenging to use (although not bad). And as for readability of the little screens, I feel that the Kaiweets HT118A is the best, and the Kaiweets HT208D is, by far, the worst. The rest of this review explains why I have come to hold these opinions.ACCURACYAccuracy is always compromised to some degree because many factors affect accuracy of DMMs including “resolution,” “range,” “number of digits displayed,” “altitude,” “temperature” and “humidity.” As I said, I’m not an electrician and, with one exception, I don’t pretend to understand how these factors affect accuracy. But there is one overriding aspect to accuracy you might wish to consider: each manufacturer states (i.e., tells you) the various accuracies of the particular DMM right there in the user manual. Moreover, the user manual states SEPARATE accuracies for “DC voltage,” for “AC voltage,” for “DC current,” for “AC current,” for “resistance,” for “capacitance,” for “frequency,” and for the various other types of measurements within the particular unit’s capability.All four DMMs were checking the DC voltage from the same, fresh, 9-volt battery; all are shown in “hold” mode, and I have removed the probes to avoid cluttering the pictures. In my evaluation I looked at the stated accuracies for “DC voltage.” All I could do was “compare” them to each other because I don’t own any expensive highly accurate measuring equipment. As you can see, they all show different readouts for the same battery.Here are the results:For the Kaiweets HT208D, the user manual says the accuracy for measuring DC voltage is: plus or minus (0.5% + 5) for all DC voltages from 600 mili-volts up to 600 volts, and plus or minus (0.8% + 5) if you’re checking a source for up to 1000 volts.At first this stated accuracy notation was entirely Greek to me, but I read and learned how to understand this “plus or minus (0.5% + 5)” stuff. It’s way too complicated to put into these remarks, but you can learn from an nifty article at a website called “bettertechtips,” found at https://www.bettertechtips.com/how-to/digital-multimeters-accuracy/ But there is one piece of information I can tell you, and that is: the smaller the numbers inside the parenthesis, in this case the “0.5%” and the “+ 5”, the more accurate the DMM’s reading will be. In other words, it tells you how far off the source’s (e.g. a battery’s) actual voltage might be from what the DMM readout tells you it is. The one exception that I mentioned above has to do with the number of digits displayed on the DMM’s screen, but particularly the number of digits to the RIGHT of the decimal point. So if the DMM shows a total of four digits but only TWO digits to the right of the decimal point, the stated accuracy is not as good as a DMM which also shows a total of four digits, but THREE of those digits are to the right of the decimal point. (This is referred to as the DMM’s “resolution.”)For the Kaiweets KM100, the user manual says the accuracy for measuring DC voltage is: plus or minus (1.0% + 5) for all DC voltages from 200 mili-volts up to 600 volts. As you can see, the “percentage” inside the parenthesis for this DMM is 1.0 as opposed to 0.5 for the Kaiweets HT208D. This means the stated accuracy of the Kaiweets HT208D is better for DC voltage than the stated accuracy of the Kaiweets KM100.For the Kaiweets HT118A, the user manual says the accuracy for measuring DC voltage is: plus or minus (0.5% + 3) for all voltages from 600 mili-volts up to 1000 volts. But the “+ 3” is smaller for this DMM than the “+ 5” for both the Kaiweets HT208D and the Kaiweets KM100. Because “3” is smaller than “5”, the HT118A is stated to have better accuracy than the other two Kaiweets DMMs.For the Mestek DM100C, the user manual says the accuracy for measuring DC voltage is: plus or minus (0.5% + 3) for all voltages from 999.9 mili-volts (call it: 1000 mili-volts) up to 999.9 volts (call it: 1000 volts).At first glance the stated accuracy of the Kaiweets HT118A for DC voltage appears the same as that of the Mestek DM100C, but it’s not. In fact, the accuracy for the Mestek DM100C is MUCH BETTER than that of the Kaiweets HT118A for one critical reason: The Mestek DM100C’s “resolution” is better for DC voltage than that of the Kaiweets HT118A. As you can see in the pictures, the Mestek DM100C has THREE digits to the right of the decimal point, while the Kaiweets HT118A has only TWO digits to the right of the decimal point! To put it simply, the “resolution” of DC voltage of the Mestek DM100C is much better than the resolution of all three of the Kaiweets DMMs mentioned above. But keep in mind that I’ve only spoken about the readings for DC voltage for these four units. So this doesn’t mean that the Mestek DM100C performs better than the three Kaiweets units in all other types of electrical measurements. Moreover, just how much accuracy is necessary when you’re measuring DC voltage from 9 volt batteries? For non-electricians like me, not a lot, but for real electricians, the degree of accuracy is very important.EASE OF USEI feel that the Kaiweets HT208D is the easiest to use for two reasons. First, because there are only two ports for the probes to connect to the unit. Just two. The black probe always connects to the clearly-marked COM port and the red probe always connects to the one and only other port. No thinking is required! Meanwhile, the Kaiweets KM100 has a total of three ports. The black probe always connects to the clearly-marked COM port, but the user has to decide which of the two remaining ports to use for the red probe. It’s not a hard choice by any means, but it does require a mili-volt of brain power. The Kaiweets HT118A and the Mestek DM100C each have a total of four ports. As with all DMMs, the black probe always goes into the COM port, but you’re left to decide which of the remaining three ports to use for the red probe. For the Kaiweets HT118A, once you have figured out what you are going to use the DMM to measure (e.g., testing DC voltage, AC current, resistance, capacitance, etc.), the Kaiweets HT118A tells you which port to use for the red probe by means of flashing lights – like the “idiot” lights on many cars. So, again, no brain power required. On the other hand, the Mestek DM100C is not so generous; there are no flashing lights. Once you have figured out what test you want to conduct with the Mestek DM100C, you are left to decide where the red probe goes. Again, it’s not a difficult choice, but it’s up to you to determine.The other reason I consider the Kaiweets HT208D to be easier to use than the others is because there are fewer settings to choose from. All available functions are accessible by choosing from only eight settings, while the Kaiweets KM100 has 19 possible settings, the Kaiweets HT118A has 10 possible settings and the Mestek DM100C has a whopping 29 settings. On the other hand, however, the more available settings you have, the higher the unit’s resolution will be. For example, when testing DC voltage, the Mestek DM100C’s 29 possible settings allow you to put more digits to the right of the decimal point, while the Kaiweets HT208D’s eight settings offer less flexibility. The more digits to the right of the decimal point, the better the resolution.READABILITYI found that the best readability of the four DMMs shown in the pictures is the Kaiweets HT118A (third from the left). It is readily readable in both dim and bright light, and from all angles. The second best for readability is the Kaiweets KM100 (second from the left), also visible in both dim and bright light. Both of these DMMs display black numbers against a light background. The third best is the Mestek DM100C (on the right), also visible in both dim and bright light, but not as good as the previously-mentioned Kaiweets DMMs. The least visible is the two-color Kaiweets HT208D (on the left); it’s pretty, but that doesn’t make up for its visibility problem. It is easy to read in dim light, but in bright light it is quite challenging to read and that’s putting it mildly. Both the Mestek DM100C and the Kaiweets HT208D use illuminated numbers on a black background – which seems a little harder to read than black numbers against a light background.
