Mastech 5908C Multifunction Tester (Lite)

[AndyD]

I can't comment on many of their products but I've been hands on with serveral testers of theirs and Mastech wouldn't be a brand of choice for me. If I was looking for budget testers I'd go more for the Uni-T brand or even Toptronic which are usually rebadged Brymen testers.

I would stay far away from UNi T ... the equipment i have used would get the same rating as SA (junk) ...after returning a few faulty items( they dont last long)...they were returned to me in the same condition (not working) ...i have decided to dump the rubbish...maybe i have been using fluke too long...i still have all my original fluke testers...not one other brands has lasted past 5 years.

I can second that Ians. ABSOLUTE JUNK. Way way overpriced for secondary school electronics.

I also stay away from major tech brand... also budget plastic junk ...however they have branded products from kyoritsu under the major tech name ...kyoritsu i give a thumbs up...it is a quality brand...just look out for the K on the major tech units...thats how you can identify them...worth what you pay for them.

[AndyD]

Agreed, Kyoritsu are a very solid brand, I have several of their testers and some of then are probably at least 20 years old and still in calibration.

Hi

I was surprised on the comment over the Uni-T
I was a fluke man and always bought the fluke with clamp tester for both Ac and DC - They were perfect and then suddenly started having problems and every time was a 2K repair bill.

Tried the Uni T and have not had problems - Once or twice when there was a problem it was returned and repaired at no cost.I have about 8 of them
I was led to believe that Uni T will repair at no cost as long as the meter was not abused - My guys are good at abusing everything.

I was also surprised about the Uni-T comments. I've recently got half a dozen Uni-T UT210E clamp meters which I picked up on offer in the UK and I like them a lot. It's a DC and AC current true RMS clamp and has a 2Amp range which has 1mA resolution so I find myself using it as an earth leakage clamp as well as an all-round tester. It's pretty damn accurate, it's small and easy to carry, it's solid and I just like it. Best of all it cost the equivalent of about R550.00. If I really had to find fault with it I'd say the leads it comes with are a bit hard and inflexible for my liking but overall I'm very impressed and would recommend them if you're budget won't allow a Fluke or Megger.

Hello Bro's.

I need to know the resistance of the element connected in parallel R49. Possibly a photo with better quality of these elements with color marking.

Thanks in advance for every answer.

Probably the same value as R52.
Chances are the Opto Coupler may be faulty too.

It's not the same. I operate photo from the beginning of the conversation. Have another colors but photo is unreadable

[Justloadit]

The last picture is too poor in quality to make anything out.

And funny, but in the global search engine only this forum have someone commented on the inside of the multimeter. So I hope that the users from the beginning of the thread will have their say.

[Chrissos]

Andy D, if you have this multimeter, please see inside again and read value of resistor R49 or send better quality photo. THANKS

[AndyD]

I'll crack it open and take some photos when I'm in the workshop this coming week.
