Best tester for new electrician

[LectriCare Ian]

Here's a tip, look for a nice Fluke 1651.The 1651 is the cheaper 'entry level' model often bought 'just to pass the exams' so there are some really nice ones out there. It does not have the 'Auto' function or 'Rising Ramp' test found on the mid range 1652. Both of these are part of the RCD testing section and are well worth having. 'Auto mode' means that you can work through the 6 RCD tests (1/2I,I and 5I each at 0 and 180 degrees) without having to return to the tester each time. You stay at the distribution board and reset the RCD each time it trips. The test results are stored and can be scrolled through once the test is complete. The rising ramp test is useful for fault finding since it shows the actual current flowing when the RCD tripped. A 1651 can very easily be upgraded to 1652 spec.

Thanks the 1651 looks ok and are going for a few hundred pounds. Seems a good place to start.

The difference,in cost, between some second hand units,and some of the higher end older models,is a lot less than it was.

The 1720 cost has been displaced by the new model range,and i wouldn't mind betting,the difference between one of these,and what you would spend on a lesser,older model,is only a portion of the value of the mobile device you own!

Admittedly,i would sooner spend on kit,than owt else,other than family...but my missus has a pal that give £600 for a handbag,and no one threw fruit at her...

Save a bit more,and get what you want.

You will be happier,and more inclined to "love" your device,and learn it's every function.

One enjoys one's food more,with one's favourite spoon...as against the spoon you borrowed off a tramp...

As eloquent as ever . You have made a good point though.
Respecting kit is the mark of a good workman.

Normally I'd agree but doing without kit while you save isn't always best.
Sometimes its better to buy once loved older kit while you build up wirk and funds. Then invest in a newer more modern model and keep the older one as a spare.

 

[ruston]

In your situation I tend to agree.
I have done the same , especially with gear that only has infrequent use . Having said that , Peg is right too.

A nice tester, properly refurbished, is better than new. Am I being bigheaded? No, because refurbishment (servicing if you like) attends to any known weak points. Modern lead free solder does not flow very well, so larger transistors and resistors often benefit from having a little extra applied. The push towards cheaper calibration options such as 'calibration days' at wholesalers means that very few testers are getting the proper 'clean, service and calibration' these days, as was the practice years ago. Calibration is not the same thing as adjustment. Modern methods of adjustment often involve a PC and software, rather than the older preset potentiometers that could be 'twiddled'. Resistor values do change and 'settle' as they age, so adjustments may be desirable after a year or two, but this takes time and requires 'product knowledge'. In other words a tester that has been correctly adjusted as part of a refurbishment may keep to specification in the coming years better than a new one who's factory fresh resistors quickly change once it's put to use.

I'm happy to go with once loved as you worry less about tye day to day knocks and scuffs. Nothing worse than shiny new kit you fret over...

Can't bring myself to buy fluke stuff. I mean what of all the names you can think of would you call a piece of precision measuring equipment fluke? I mean WTF? We had robin equipment on the leccy board and.. remind me does the forum have a no name and shame policy? Had a megger CM500 once working for myself in '02 which was their top end then for a few years, was a fine bit of kit but had a bit of a problem (rotary selector a bit funny) and their laughably expensive "we'd rather you bin it" repair price put me off the brand on principle - I was ready to drop a £1k on a new one but for that. so had 3 (2 nicked) metrel eurotest AT's in succession (again £1k top end) and nice enough bit of kit but never felt that robust.. last one went squiffy after a few years and the repair cost was £3or400 so I went for a "cheap" martindale 4000 at only couple hundred more, seems allright/good value, includes the remote tip, rechargeable batts etc and being half the price if it packs up after 3 or 4 years or gets pinched I'll be less fussed.

Fluke is the name of the guy who started the company, John Fluke. The Robin testers are very good but sadly the D-Lok system for No Trip loop testing only works on magnetic RCD's and not the newer electronic types. It's a full 25A loop test which leads to a very tight specification of 2% and 2 or 3 digits (depending upon which manual or brochure you're reading).

Fluke is the name of the ex- US Navy chap who founded the company, John Fluke. What's in a name? Robin is a 'made up' name for the UK market. Now owned by Fluke, it was started by the guy who owned Eagle products (importers of test gear, PA systems, power supplies etc.) I guess he liked to name his brands after species of birds. Most Robin products were made by Kyoritsu Electric Works, better known now as KEWtech. The D-Lok system for no-trip loop testing seen on the KMP 4120 models is a British invention by a Mr. Martin Litherland. It allows for a 25A test, so these models have a good accuracy spec. compared to later testers. Sadly the method only works for electromagnetic RCD's (incorporating a ferrite core) and does not 'fool' the modern electronic types.

I'm hesitant to add my simplistic suggestion after the extremely well informed posts by Ian... however I really like my Metrel MI3000. It's easy to use and affordable, I've had a second hand one for 3-4 years and had no problems.

However, I'd appreciate your work phone number Ian as if I do get a problem with it I would give you a ring, also do you offer calibration services and if so what price for a Metrel MI3000? Feel free to PM if you prefer.

I always use separates. I like the Megger MIT320, LRCD220,RCDT320 all of which I have. Before that I had the Robin yellow bricks which I still have.
