Top Customer Reviews
Harold E King from Kentucky (yes we have running water & phone service here!)
I was torn between spending a lot on a Fluke and this DMM, but decided I would never need the quality of the Fluke - hope I made the right decision and that the replacement unit will work OK.
I will edit this review when new meter received.
Edit Jan/2015: I received the replacement unit but it also had the same problem. On closer examination (not believing two consecutive could be bad) I inspected the leads. On the lead ends that connect to the meter there are factory installed plastic tips (not the protective caps). I suspected poor contact with the meter's female connections. I connected my old leads from the meter this Extech replaced and the problem was not there. I contacted Extech tech support and was told there was a protective coating on the tips to prevent corrosion in storage (why was this not noted in instructions). The tech suggested I clean the test side tips with acetone. After doing this the problem got better but the leads still do not perform as well as my old leads. I still suspect a problem with the male contacts not being spread enough for really good contact with the female plug in the meter.
Working now with Extech to see if I can fully resolve the issue to my satisfaction after Extech product support replied to my review - which shows good product service.
Edit Jan9/15: Just got an email response from Product Manager. We'll see what happens.
Edit Jan 23/15: Extech sent new leads which fixed the problem. So far customer service response has been good. I upgraded the number of stars to 4 and will reassess as I work with this meter.
