4.0 de un máximo de 5 estrellas MS8269 Traditional DMM with LCR 26 de marzo de 2011

I purchased this unit mostly because of quick field diagnostic LCR range with max 20H combined together with standard options. Capacitance is only from nano to 200 micro so basic but is there. Internal fuse (except 10 Amp range un-fused) is self-resetable as well so at this point not having it auto-range is irrelevance besides the convenience issue considering you know what you are checking and if not then no pain. You get strong case, separate 9 volt battery compartment with spring loaded connectors held by metal threaded screw in brass insert, system board is clean (yes, I had to look at the guts as well), well shielded. Continuity is with that scratchy sound, not alike my "expensive" meters, but for some purposes I do like it and use it, like checking potentiometers from audio equipment for worn-out track. I found inside on the unit's board few spots of resin deposit here and there, but all main parts are surface mount with some understandable exceptions. I checked measurement again couple of known calibrated meters, then one fancy RMS and oscilloscope. All pass within specifications including capacitance and inductance. IF they weren't, unit appears adjustable within reason, but I did not have to go there. One nice thing - hFE and temperature are on separate plug-in module which is to me an indication of good technology and logical planning. Also, the on/off switch on the unit is not sticking out - another indication of good thinking on the part of the designer. Hold function is certainly not capture type, just the screen freeze - if you want active one, then cough out few hundred bucks and say hello to FLUKE 87 or it's close relatives. Over whole, this MS8269 meter is good value, appears sturdy and works well for the money paid. Very good tool for diag on audio amps, power supplies including printers also standard communications relays and other things medium. In case you need IC work it is good for a field work but not enough for bench, and if you look for A/C units and larger equipment tests, then you know what you need - good clamp-on and dedicated LCR with 20-40 mF range. For all those that are looking for a gift ideal for Handy-Man in the house you may consider this one or MS 8229 for 20 bucks more MOL. I have been in electronic business for a while and trust me - there is nothing more embarrassing then fried diagnostic tool caused by the so called "operator error". LOL When you need to check user manual for spec details, go to Sinometer website - prior it used to be under Mastech so some search engines on the Internet may still give you Mastech link for information.

4.0 de un máximo de 5 estrellas It's Pretty Good 4 de abril de 2011

It does what it's made to do and there's nothing wrong that would disagree with it's spec sheet.

My only gripes would be 3 things:

1... It's Lx measurments are just not sensitive enough for most electronic applications seeing as 10 microhenry is it's finest/lowest level [0.01mH/10uH] and could only serve as a base reference to help verify inductors you already pretty much know what they are (at that level).... but not homebrew inductors that require accurate readings.

2... I would've preferred if they could have made the current (<200mA) connector the same as the Volt/Ohm connector... the repeated switching is annoying.

3... Lastly- the grippers on the back for the test leads are strange and not well designed, be prepared to keep them wrapped around or in a case.

Otherwise, I've really enjoyed this multimeter.

The meter is as accurate as specified. The temperature measurements are identical to my Fluke's. However, the meter is challenging (for me) to use -I dislike the effort required for finding the setting to be measured- it is unnecessarily frustrating. Moreover, the cable connection quality is beyond random. A dead short can frequently read 1.2 Ohms. Spreading the inner pins helped for three measurements to get a low 0.2 Ohm reading.. The cables' measuring tips are well designed -have a comfortable feel and removable protective tip covers for, say, measuring voltages between TO-92 semiconductors without concern of shorting connections. I replaced the meter inserts with expansion banana connectors, and now get 00.1 Ohm with cables shorted. For precision measurements, first look carefully at the specifications of this meter: for example, matching resistors below 0.1 Ohm is not possible..Inductors and capacitors can be similarly problematic. The saying "You get what you pay for" holds true for this device..
3.0 de un máximo de 5 estrellas Nice instrument except for one serious flaw 31 de mayo de 2013

As a measuring instrument the meter works as expected. However, there is a problem that renders the unit nearly unuseable. The probes that come with the meter do not make reliable contact with the instrument. On the first unit I got one probe would not make steady connection with the ground (black opening). I examined the end of the probe and found that rather than being a spring structure it is merely a metal (probably plated brass) rod that has been split into 4 segments. The splits are very asymetrical so one segment is very thin and weak. Further, the contact area in the meter is a short length of thin, flimsy, distorted metal tube. The net result is that the probe will not make contact unless you push it to the side and hold it. I returned the unit to the manufacturer and they were very prompt in replacing it. However, the second unit worked only for a few cycles of inserting and removing the probe (you must do this as there are different probes for different functions). I will probably end up having to manufacture a proper spring probe to fit - none of my decent probes will fit the openings.

The meter I received didn't work properly on the capacitor range. I took it apart to investigate and one of the smt resistors for the capacitance circuit was slanted and only partially soldered. The rest of the soldering and components inside looked very cheap. I resoldered the resistor and the meter worked fine. There is a reason this meter is so inexpensive, but if this is an extra meter, or you are using it to check a capacitor value now and then like I am, it serves it's purpose.
