Em7000 Analog Multimeter FET TesterGENUINE by Sanwa

I purchased this meter through Amazon and "Ace Japan" since I wanted to make sure that I was getting a Genuine Sanwa made in Japan meter and not one of the knock off copies made in China or India. You have to be a little careful since they are out there. It was delivered in about 10 days, nicely packaged, direct from Japan via certified mail no less. I had to go to the post office to pick it up, no problem. I have not used it a great deal yet but it seems to be very well made. It has all the features for which it was purchased as described. This is a FET multimeter which uses a field effect transistor differential amplifier to drive the meter movement giving it a very high input impedance unlike a standard analog meter. It has a power on-off switch which must be turned on for the meter to operate and unlike traditional meters which will make voltage and current measurements without the internal batteries, this meter requires the batteries to operate.It would be nice if Amazon carried the Sanwa case for this meter or it was available through the Japan dealers. After sizing it carefully, I purchased the Fluke C35 case for it. The meter fits pretty well with the test leads along side although I cut out the internal strap which would not be usable with this meter. The test leads are OK but it would be nice if they came with alligator clips. Not enough of an issue to knock it down from it's five star rating. All said, a very nice small meter.

This is perhaps one of the most sought after analog multimeters and you won't find one that matches it. It works so well in almost all aspects except when measuring AC voltage where the needle takes a rather long time to settle on a reading. This isn't one to bring in the field as it's sensitive and will not allow mistakes: it will blow its fuse for wrong connection. In lab scenarios this is quite at home.

I have several multimeters/VOMs, but they are all very old, and I have no doubt that some are well out of calibration. I also have a new Simpson 270-5, but at a cost of well over $400, I end up not using it for fear of breaking it. Thus, I purchased this meter for ‘everyday’ use. It has good specs (DC input impedance > 2.5 Mohm, AC input impedance >800 Kohm, accuracy of most scales is +/- 3% of full scale), and appears to be of fine quality, well made and solid, and it is easy to use, although I have only used it a few times to measure DC voltage and resistance. I found a small case (Sisma SCB17092B) into which this meter fits quite well and is reasonably well protected, to extend its calibration and life.

I really like this thing. It feels quality and the accuracy is on par with a Simpson. I like that it is so versatile. The size makes it easy to put in a bag and take anywhere. I will use this thing a long time.

I think the Sanwa EM7000 it is an excellent product.I compared it against a regular analog voltmeter (VOM), an analog vacuum tube voltmeter (VTVM) and a digital multimeter (DMM).It has higher input impedance than a VTVM, but without the 20W power consumption, the warm-up time and the scarce of electronic tubes.It has the classic feeling and tendency observability of an analog VOM or VTVM movement, but driving the galvanometer by an amplifier, not directly from the voltage source, giving more durability to the movement.It also has a very convenient mirrored dial to avoid parallax errors. The numbers and traces of the scales are very well printed.The null meter function operates wonderfully, avoiding the fear of damaging the movement because of measuring DCV in reversed polarity.Also, the null meter function does not require another set of scales, having 8 dual polarity DCV scales and 5 dual polarity DCA scales.The internal fuses are ceramic type, which gives more confidence when measuring.The range selector has a firm click when it's moved, and the turning force is the adequate to operate the equipment in a table with one handbut without rotating the body of the meter.The quality of the materials is good. To me it does not feel cheap.The probes are amazing. The tips have gold-plating, which is awesome.Also, the probes have removable caps to measure in CAT III 600V environment.The tips are not very sharp, but I prefer them that way.The cables look good, flexible enough. No complains in this matter.The solders in the PCB have white marks that indicate a rigorous soldering quality inspection.In sum, a very nicely and rigorously crafted japanese-quality multitester.Unfortunately, the equipment came with the power switch in the ON position and the 9V and the two 1,5V batteries inside the meter.So, when it arrived, 40 days after the purchase, the 9V battery was totally exhausted.A new 9V and problem solved.
