Portable Meter is Ideal for School, Hobby or Home use... 2009-11-06

By M. Sabo

This digital meter is designed to measure Volts, Current, Resistance, Capacitance, Inductance, Frequency, Temperature, Continuity, Diode, Transistor and TTL Logic. It comes with a battery already installed.

I made the purchase because of the LCR features at a low cost.

One feature I do like is the bracket that pivots out from the back to hold the meter at an angle for easy viewing.

The user manual does suffer from some poor translation. An example of this is: "After measuring completely, disconnection the test leads with the circuit to be measured, and remove the test leads from the meter." I believe it means: "After measuring, remove the test leads from the circuit and also remove the test leads from the meter." I think the idea is not to turn the rotary switch, aka Range Selector, as this may cause damage.

In measuring Inductance I used a Radio Shack 100 microheneries RF Choke, p/n 273-102C. I wasn't getting a reading at first after following the instructions. If I had read the Capacitance instructions I would have known to press the Lx/Cx button. So, I press the button and still nothing. Moving the selector to 2m or 20m I got a reading.

The reading is 0.095 at 2m and 0.09 at 20m. The selector being set at 2m means the range is from 0 to 2 milihenries with a resolution of 0.001mH; therefore, it reads as 95 microhenries after moving the decimal three places. Accuracy is stated as plus/minus 4.0% of the reading plus 5 of the resolution.

The small coil only measures at the two selector postions. The coil is far to small and under the range for the 200m or above positions. I measured a coil of 350mH and had to set the selector to 2m and got 0.365 for a reading. I would think a different position, but at least I got a reading. Just got to learn how to use it.

I much prefer a meter with an auto ranging LC meter designed into it. I opted not to build my own LC meter for this model and consider it a good choice as it has other features that I can use.

Update: At first I pressed the leads in until they stopped. Then, I was retesting and didn't get any readings. I pushed on the leads to get a bettter connection and one went down until it was flush. A final word is when the test leads are inserted to press them all the way down.

A lot of function at low cost 2008-03-08

By Roosvelt Sanchez (Dominican Republic)

I made the decision to buy this portable meter because I was looking for one that allow me to measured most of the parameter in a typical circuit. This equipment is capable to measure (within an acceptable range) capacitance, inductance, frequency and temperature at very low cost. So, I am satisfied with this one.

Good!!! 2008-02-16

By Michael Uribe (Caracas, Venezuela)

It`s a good tool for students, but it`s not enough to work...regular presicion in low measurements....just good!!!

Lots of functions at a great price! 2008-01-06

By Jimbo (Texas)

I've only had this a couple of days, but observations so far: The meter seems sturdy and solidly made with a rubberized coating on the case. The multifunction switch is slightly stiff but clicks firmly from one function to the other, the buttons work well and are seated snugly in the case with no evidence of contact problems. The test leads are fine, come with covers and caps for each end. The banana plugs have safety covers, so they may not work with older equipment. The temperature probe seems to work fine, but the meter reads only in Centigrade. The user manual is okay, many reviews complain about the grammer problems of Kaito's manuals, but they are not significant in this one. The little booklet has a key to all the buttons and switches and a little section for each function illustrating how to connect the leads with an explanation of how to get a reading. If one needs something to explain the tests, look elsewhere.
FUNCTIONS:
As noted in the previous review, ohms only to 20M, not a serious flaw in my opinion.
Capacitance: requires lead insertion into a small test socket, not suitable for polarized caps and range is limited.
Hfe: A little socket for insertion of small signal transistors, seems to work, not suitable for transistors types made without thin wire leads.
All other functions seem to work as they should.
SUMMARY:
Time will tell - if this is fully functional 5 years from now, I will consider it a really fantastic buy. As it is - a nice little meter with lots of nifty features for a modest price, well suited for the audio work I will be using it for.
