      There are certain test that require analog meters

      Overall: 4.5 out of 5

      For instance, checking capacitors, etc. The sweep of an analog meter works better than the fast changing digital readout of a DMM. This meter fits the bill for those occasions

      Don't know how this works, because the one I received did not work. No needle response on any setting. Checked internal battery polarity twice; didn't get a chance to try different batteries. Broke it (exceeded unfused current capability) while trying to get a response from 120VAC.

      Good value for the money but poor manufacturing quality control

      I have purchased many items from MCM over the years, but this meter is the first item to totally disappoint me. Out of the box it only worked on a few of the DC voltage and resistance scales. The selector switch felt like it was jamming on some of the detents, so I pulled the unit apart to investigate. I was shocked to find the power leads for the transistor tester tangled in the selector switch contacts. Further investigation found a number of cold solder joints on the main board and the transistor tester sub-board not properly seated. I fixed all of the problems and once again tested the meter. This time I found that very few of the ranges of the meter did anything at all. There is not a lot that can go wrong in such a simple meter, so I suspected the switch contacts were bad. Upon closer examination, I found that one of the spring copper contacts had a crack in it where it rubbed against the PC board. I bridged the crack with a bit of solder and the meter started to work as it should have from the factory. Overall, the calibration seems to be very good on the 0.6-60 DC voltage and all of the current ranges. The D'arsonval meter movement is a bit cheap in that it requires mechanical re-zeroing when setting the unit on its back or standing upright, but that is a minor issue for most people. The battery tester, continuity buzzer, transistor tester, and zero-ohm switch are nice features to have on such an inexpensive meter, but I personally will not likely use any of them. I purchased this meter for those rare times when I have to peak/null a voltage, and for that purpose, this unit should work fine.

      The large meter face (8x10 cm) makes it easy for my old eyes to read. I think this is an excellent meter for the price, providing you purchase it with the knowledge it does not have a high impedance for measuring micro electronics. I have several meters, but sometimes I just need a simple VOM to measure electrical where the swing of an analog meter is beneficial. This meter is excellent and is accurate for simple electrical measurements. An interesting feature of the meter is a test area for determining if a transistor is NPN or PNP. I also like the "off" feature that dampens and protects the meter movement when the meter is transported.

      I have my electronic shop and use all the time 72-8170 Analog Volt /Ohm Meter for check all rectifiers and zener diodes and resistors,ect... Has never failed me in my field of electronics, I recommend it veryexcellent.Thanks MCM for all the good equipment you sell.
