Welcome, Guest. Please login or register. Did you miss your activation email? This topic This board Entire forum Google Bing. Print Search. Read times. This is the review of the Kyoritsu multimeter. Kyoritsu is a Japanese company founded in the and since than manufacture and sale test and measuring instruments like multimeters, clamp meters, insulation and continuity testers, etc.

Kyoritsu is a well respected company so I decided to get one unit and make some tests. This model is an autorange counts multimeter and it has all advanced function a hobbyist may need: - voltage, ohm, capacitance, frequency, current measurements - continuity test - diode test - relative mode - duty cycle - high impedance on mV range - display hold - auto power off - CATIII V and CATII V It ships with batteries and a pair of test leads.

At first sight the multimeter look like good solid construction. The display is not the biggest, but it's clear and maintains good contrast on any angle. Range switch is soft and precise and almost any function of the multimeter has it own position.

The holster is made of soft plastic and seems quite reasonable for the meter price. Unfortunately the hostler is not pretuding the front of the meter so it does not protect the display or the range switch. In the back of the meter we find the tilt bail that permits to keep it in vertical position one hand test pass. On the lower part of the meter, we have the usual 4 banana jack: one common, two for the current measurements and the last for all the other functions. I tested the multimeter accuracy in DCV position and the results are quite good.

The meter overshoot a little bit at 10V. I noticed also that in the mV range it has very hi impedance something like 0,5 GOhm. Accuracy measurements where made also in the Ohm range and current measurements where we got the most accurate readings. Autorange take just little more than 1s to go from OL to 0 Ohm. Continuity test is not fast as a Fluke, but is more and more faster than the typical Amprobe meter.

Diode test has an open circuit voltage of 1,6V so it's just for testing diode and transistors. Capacitance test is specified up to uF and it really overload with a bit more than this, while on the other end, it can consistently read also value of 0,46nF.

The meter uses reasonable shunts resistors like Ohm, 1 Ohm, 0,01 Ohm so it will not have too much burden voltage when measuring low currents. Battery consumption is typically less than 1mA, and never bigger than 1,5mA.

I cannot measure any power drain when the meter is in auto power off state. At this power consumption the two AA cells will last almost forever. At 1,7V the display begin to dimm and the meter shut off.

Opening the meter reveal a quite simple construction. Input protection is not the best I have seen, it uses only some resistors and one PTC no mov or spark gap at all. There are some unpopulated footprints on PCB that I can guess where originally drawn for some more input protection components.

The current measurement are protected by V rated fuses. On the pcb you can find also some transistors, some trimpot for adjusting the calibration of the meter and a bunch of passive components.

Banana socket is well engineered, the contacts are not split type and they are completely secured to the case. This construction should avoid any mechanical stress to reach the PCB during leads insertion. Last but not lest PCB wiring, component placement and soldering job are good. My only concern with this meter is the input protection so I decided to connect it to the V mains and stress it a little bit. When it was connected to mains I stressed all functions of the meter including Ohm measurements and range switch.

The PTC seems to works very well and the meter recovered in few seconds from the stress. After this "extreme" test I checked again the accuracy of the meter and it was OK. What is missing to this meter? I think this is a good meeter for starters and maybe it can also be considered like a professional entry level. CAT specifications seems to be reasonable and the V HBC fuses give me the confidence that if you really need you can stick it to V.

For the same price you can find some meter with more functions but I think build quality of this meter is a little bit above the average the other cheap Chinese meters. If you are on a low budget but you occasionally play with mains maybe this meter can be a good and safe buy.

If you want to see some photo of the meter and the teardown jump to my website HERE. Thanks for the review and pictures. Keep them coming. BTW, where is this meter made? I can't see from your pictures? Robomeds Frequent Contributor Posts: Country:. This appears to be the same as the Elenco Dave reviewed.

Slightly different case but I bet the guys are the same. Thanks for sharing. Wytnucls Super Contributor Posts: Country:. Quote from: retiredcaps on March 14, , pm. Lightages Supporter Posts: Country: Canadian po. From what I see, t is not too bad. I think the Digitek DTR is a better buy. This meter has same serial number style and same red "quality pass" sticker like then the Elenco in Dave's review, so it most probably come from the same factory. I really don't understand why cheap meters still use only V fuses, these V fuses costs almost the same.

Digitek DTR. I think the V fuses are cheaper because many Euro power cords all? Germany only? The V fuses are also smaller. When every fractional cut in costs counts the fuses are an easy thing to skimp on. For most home and even non-electrician work, I suspect the V fuses are more than safe enough. I think it's a reasonable trade off so long as the meter is correctly labeled.

Thanks for the review and tear down. The chassis of this DMM does not appear to be double insulated. Brymen, despite its low cost, gets its meters externally safety tested since the mid s and nearly all are double insulated. Electrical safety is always good to have. Compare the chassis wall lining against the Kyoritsu chassis: Alas, CE certification is generally of little value. I know Brymen very well because I sell this brand on my store. Also this Fluke 17B seems to costs more than double the Kyoritsu There was an error while thanking.
