Top Customer Reviews
Auto-ranging works very well for a meter this cheap. I know better than to compare this meter to any that cost 5 to 10 times as much ! This model has truly superb "bang for the buck". It accurately measures resistors in the 1.0 and 0.10 ohm range, and it zeroes out to 0.00 ohms when its probes are shorted together.
The cap/diode/transistor plug-in test adapter is very handy. However, the transistor hFE test function seems nearly useless due to it biasing the transistor with an incredibly tiny current. Most discrete transistors are simply not biased this way in circuits which makes the meter's reading all but useless for most practical purposes.
All-in-all, I love this meter. Comparison of other meter models' user reviews against this meter's reviews led me to get this particular model. It is far, far better than the cheapie $10 to $20 meters. It's worth much more than the thirty-two clams (shipping included) I paid for it compared to all its competitors in its 25 to 50 buck price range.
A general observation: Mastech bench top power supplies also seem to be top notch for their cost. No other manufacturer seems to come close to matching Mastech's value and quality for their product's cost.
First let me say that nearly every DMM on Amazon has at least some very negative reviews. It seems that no matter how well made a DMM is, there will always be some that are defective, or some users who don't know what they're doing and fly off the handle in rage in their review. Reading some of the negative reviews for this Mastech MS8268, it seems very likely to me that many of those reviewers didn't know how to properly use this particular DMM. Every DMM is slightly different, and even if you have experience with another brand and model, you may still have to read the directions for this one.
Also because this one is so inexpensive many people may assume it is broken when actually they just aren't operating it correctly. If they spent $300 on an expensive model and it didn't work, they would be much more likely to read the manual better and assume they were doing something wrong. So there can be selection bias at work, especially if we've already read some negative reviews on the item.
For instance, I initially thought the continuity function was broken because I'd read some reviews where others had that problem and mine wasn't giving the alert sound when I turned the dial to continuity and placed the leads together. Then I read the manual and found that I also had to press the select button to test for continuity. I did that and it worked perfectly.
Also, the digital display will fluctuate wildly when the leads are not touching anything. This is normal.
Also, when testing voltage be aware that this meter is auto-ranging, so it will automatically display a reading anywhere from volts to millivolts. In other words, you may test a 9v battery and get a reading of 300.21 You may wonder how a 9v battery could possibly have 300 volts! But if you look more closely you will notice that the volts has changed to millivolts. In other words the battery is so dead that there isn't even a single full volt left in it and the meter is only picking up 300 millivots left in the cell.
Basically what I'm saying here is you may want to be careful and patient and educate yourself on using DMMs in general and this one in particular before you create and unnecessary hassle for yourself by returning this one as a piece of junk.
There are lots of good video tutorials on Youtube for learning how to use a DMM. I recommend taking some time with them and also reading the manual for this one if you run into problems. If all of that fails, then maybe you truly do have a defective one. Mine however is working perfectly for testing continuity and voltage in both AC and DC. Build quality seems indistinguishable from other professional quality tools I have used.
I'm very pleased with this purchase and recommend it to others.
