Average Reviews:
(More customer reviews)The MS2108 does everything it says it does, but the design could use a bit of polishing. First, the clamp reads AC and DC currents, but there is no way to do it through the probes. The AC current seems accurate, but reading DC current takes some getting used to. The basic issue is that the zero is not stable. Pushing the yellow "select" button sets the reading to zero, but it takes awhile to stabilize. Expect to spend 5 to 15 seconds fiddling with the button before zero stays put. One reason I purchased this model is that the minimum DC current resolution is 10 milliamps. However, the last digit jumps around a bit, illustrating the difference between resolution and accuracy.
To be fair, most DC clamp meters offer only .1 amp resolution and this might be why. Virtually all of them are based on linear hall effect ICs, and it is apparent that the signal level associated with tens of milliamps is low and noisy. AC current readings are always credible, but I don't trust the DC readings at low current without flipping the direction of the wire and comparing the plus and minus readings. At high currents the DC stability seems as good as for AC.
There is one oddity in the selector switch, which I presume saved a switch contact to allow use of a standard switch. There is just one setting for both AC and DC voltage. You have to use the yellow button to toggle between the two. Default is AC. If there was a dedicated setting and just one off position instead of two, life would be easier IMHO.
My meter was ordered from the source. It arrived OK but took almost two weeks by overseas mail. No manual was in the box, and when I tried to download it from the factory web site the link didn't work. An email to customer service resulted in a pdf that I had to print myself. The pagination is set up in publication format, so I had to stack the sheets and staple them in the middle with an oversize stapler to get the page order right. That and trimming to size with a paper cutter resulted in a 52 page manual. I contrast this with the straightforward 8 page manual that recently arrived with an LCR meter. I have yet to learn how to use all of the features associated with the four function buttons. It takes all those pages to explain it. I am impressed that it can test capacitance and measure frequency using either the probes and the clamp. The abilities to hold a reading and measure inrush current are nice too.
The meter is well enough built and fits the hand comfortably. Premium features like a switchable backlight for the LCD and an LED to illuminate the clamp jaws are fun, but I'll rarely use their battery eating capabilities. Altogether I'm pleased with the MS2108, but it does fall slightly short of a totally rock solid professional tool. I can live with that given the reasonable price.

The newly released Sinometer MS2108 is a versatile and invaluable tool for electricians, technicians, professionals and alike. It's small in size and can be easily be used with one hand. You can use it to measure AC/DC voltage and current, resistance, capacitance, frequency, duty cycle, continuity and even diode test. This true RMS clamp meter has inrush current measurement, which is designed to capture inrush current accurately and , most importantly synchronously and provide readings that accurately depict what the circuit protector experiences. Other features include back-lit LCD display, jaw lighting, MAX/MIN, data hold and etc.
