DR #18 - $20 Multimeter Review - Crenova MS8233D

everyone welcome to duality repair tonight I'm going to be reviewing this Crenn OVA ms8 233 D multimeter this is a nice Auto ranging multimeter and it's a really good price for everything that you get so let's take a quick look around it's a really compact unit fits in your hand really nicely it's got a nice bright orange case and everything is clearly labeled on the front the backs got the standard battery compartment and it's got a 9-volt battery that it comes with it's got the 2 pro bleed holders there which is nice and then of course that's got the kickstand so you can set it there when you're doing your work and we'll go around the dial here obviously we have our off down here measures DC voltage AC voltage resistance it'll check your diodes and continuity with an audible beep which we'll check later it checks frequency which I haven't checked yet it can measure current in micro amps milliamps and amps in the AC region and then of course you got your off so a couple nice things about this it's got a really nice solid turn you can hear it click it also tells you when it's ready to measure in that setpoint by an audible beep so that's pretty nice it's got this function switch really this is just used for the diode continuity you can see it starts in the diode mode if you press function goes to continuity mode and then function brings it back to diode mode it's got the hold function which allows you to hold at the voltage that you're measuring at the max function which allows you to measure and hold the highest value and it's got this nice really nice really bright screen here so the only downfall that I've seen so far with this is that at a certain angle you cannot see the screen with that backlight on the backlight off you can see it I know you can't see it on camera very well but you can see this from any angle with the backlight off with the backlight on I can see it in this angle left to right it looks pretty good but when you're angling it like this so from looking from top down that kind of drowns out the backlight kind of drowns out your LCD screen so that's a little bit of a negative but really it's not a big deal and this this is a really nice light the only nice feature ever to use this as far as cosmetically yeah it's it's it's a really nice little compact meter and the other nice thing about this meter is it comes with a lot of stuff so comes with your standard probes you had these red lasers like your standard probes right for measurement it's got the probe covers on there right now standard probes another nice thing comes with these second probes with alligator clips on the end so if you don't feel like probing if you just want to clip onto something say ground chassis ground and then you want to probe with your other probe it allows you to do that that's really nice it of course comes with the instruction manual and I flipped through it a little bit the instructions actually look pretty thorough and readable and it comes in multiple languages so this is really nice and it even comes with a nice zip up carrying case it's a little lined pocket in there you put your meter in there you put everything in there and it's really it's really small so you can see it's basically the size of my hand so all of this stuff that's in there and the best part this is twenty dollars this is a twenty dollar meter from Amazon unbelievable I got this thing delivered less than 48 hours for free less than 48 hours after I ordered it $20 on amazon amazon great deal so that's that's the overview let's go ahead and test at least some of the functions here alright first test will test the DC voltage measurement so I have the meter hooked up to my DC power supply and we go ahead and start increasing the voltage you'll see if attracts so I'll just stop at maybe ten volt increments we start there so here we go we have ten volt on my power supply and I have 10.11 volts on my meter now bear in mind this power supply is not calibrated so this looks pretty good up to 10 volts let's go up to twenty twenty point one also 0.1 volts off good let's jump up to fifty volts 50.2 looks good and I'll change ranges here and I'll go up to say hundred volts and 100.3 so looks fantastic all the way to up to 100 volts DC I have the meter hooked up to a my AC outlet and it's reading a hundred twenty point six volts AC so I'd say that checks out let's move on to resistance I have the meter hooked up to an 8 ohm resistor and as you can see it's reading exactly eight points her ohms fantastic let's move on to diode and continuity let's check the diode function I have a standard diode in front of me with one orientation we should read open and with the other we should read between point six and point seven volts so here we go alright open in that direction let's switch the leads around I should read between point six point seven volts there we go six hundred seventy four millivolts perfect diode function works perfectly let's go ahead and check the continuity function while we're here again I'll keep the dial on the diode continuity switch and we'll just press the function button you'll see it in here switch over to the continuity let's check continuity of this small little cable here here we go here we are in frequency mode the supposedly you can test up to twenty kilohertz so we'll go ahead and start with one kilohertz I have the meter hooked up to the headphone jack of my computer and I'll just play a few test tones through YouTube so here we go here's one kilohertz alright and it's reading point nine nine eight kilohertz that's good let's go to two kilohertz two kilohertz is reading one point nine nine six quartz great and one more let's try 10 kilohertz right in the middle the range 10 kilohertz is reading nine point nine eight kilohertz Wow alright here we are back at the DC power supply we'll go ahead and check the milliamp function first I don't think my power supply is sensitive enough to be able to output in the micro amp range so we're going to test milliamp and amp we'll start with the milliamp I have the power supply constant current set to 100 milliamps so the power supply will not output more than 100 this input on this meter can only withstand 250 milliamps so I will not get anywhere close to that limit so let's go ahead and test it out crank up the voltage you can see we have about 100 milliamps on the power supply and we're reading 100 point 4 milliamps on the meter pretty good alright let's test amps I move the probe to the 10 amp input and I've changed my constant current setpoint on the power supply to 500 milliamps or half an amp that's the highest that this power supply can output so let's go ahead and crank it all the way up and see what we read so the power supply reads 493 milliamps and the meter is reading 0.51 amps or 510 million pretty good alright to wrap up I really like this thing it's it's really compact it's easy to hold it's easy to use you get all these functions with it all the functions work really well you get all the extras too like the carrying case you get of course the instruction manual and you get an extra set of leads with the alligator clip so you get the 9-volt battery to get started this thing is just really nice in 20 bucks on top of that so really just a great value go ahead and pick yourself up one of these if you're in need of an inexpensive reliable meter thanks for watching we'll see you the next one you
