Question: Can it measure DC current by placing the leads in series in a circuit (like a non-clamp meter), or only via the clamp? The manual only mentions clamp
Document: I've compared its readings to a much older Fluke clamp-on meter and it appears to be reasonably accurate. I have noticed a few irregularities that some with more critical needs may find deal-breakers. There doesn't appear to be a zero function for AC current or ohms/resistance. It appears the ONLY zero function available is for the DC current mode (still difficult to get absolute zero). Unfortunately, the manual isn't written very well, so it's hard to know for sure.
I bought the cheapest clamp meter that would measure DC current and ended up with a well made and versatile instrument for a modest price.AC / DC switching is, in practice, not an issue. Hold, max hold and min hold are useful. Frequency measurement on both the voltage probes and the current clamp are useful as well. Good backlight, nice soft case, good probes - though clips as well would be useful. Instrument has a good, solid feel to it.
This is an excellent meter for the price, in fact it is just an excellent meter, period! True RMS with AC/DC clamp and inrush current measurement? WOW! I bought this one for my son and he loves it. He hasn't had it for very long but it is already proving to be just what the doctor ordered. I have one somewhat like it except I don't have inrush current measurement! My meter has been very reliable for more than a year.
Does everything I need and feels well made. I paid only $78 on Amazon which feels like a bargain. Recommended.Incidentals:Do remember to remove the leads when using the clamp to make current measurements.I should have ordered some alligator-clamp leads at the same time, this only comes with the pointy kind.Suggestion to manufacturer: Make the arrow on the dial white, with grey-on-grey you can't see what it's pointing to unless in bright light.
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.
Have not used it a whole lot, but so far it has worked perfectly. I originally purchased it to measure DC current on a trailer I have, and it worked a treat. Later used it as a voltmeter on DC circuits, and that worked fine as well.
I can say the meter performs as expected for DIY. It isn't perfect, but if I wanted perfection I would have gone to Greenlee or Fluke or something like that. My bigger issue with the meter is that is only CE marked. After having spent some more time researching test leads I can say it would be forced off my buy list for not taking the time to get independent certification from UL CSA or TUV.Please read the comments before writing your own.
Fit and finish just as good as Fluke.I have a Fluke 902(for years) and a really old 77 and this Sino beats them handily on both AC and DC accuracy. I set up a test circuit and made several "runs". I had to calculate variances based on resistance and voltage but there is no doubt that the Sino beat the Fluke especially at low current and voltages. As much as 10% of the reading.Now the reason I bought it.
I bought this unit because I needed both AC and DC current measuring in one tool. To get that on well know brands like Fluke, you have to pay 4 times more. When I got it, it was so good that I bought a second one for a relative that does electrical installations and he loved it too. The problem found by the previous reviewer about getting an initial zero readout on DC current is true. You need some patience to calibrate it when reading low currents.
This doesn't instill much confidence when making AC current readings below 1 amp. In ohms/resistance mode the display usually hovers between .2 and .4 ohms when the pos & neg leads are shorted.For the money, I still think this meter offers good value, especially considering it's true RMS, has the inrush current function, and is reasonably accurate.
Answer: yes
