One thing to be careful about brand X test leads or brand X DMM is be sure they truly live up to the specifications. Safety is a big concern if tools are used in kV environments.
It can say its CAT III 1000V – 10A capable, but who certified and tested those leads to be CAT 3?
The same person who certified :
Hirschmann - AEG - Bosch - Siemens - Philips and others .
Old electronic measurement devices can still be accurate, but as parts age, how safe will they be if you expose them to their rated voltages, specified when the device was new?
Since when , the external case ( isolation of the meter ) ever had an expiration date ?
Since when , the German tools and devices , ( who historically
was the leaders in everything have to do of building tools for the manufacturers the
last 60 years ) , had safety issues !!
Do you know anything about Rubin's ? and how to use them in mechanical designs ?
Does the phrase " Swiss made watch " has any value to you !!
Think again , when you do comparisons about " accurate and precise " .
The U.S. called as ( New Land ) , because its " New " , the old one ( EU ) its the place that everything had be invented.
And Greece , are the source of maths, and teacher of the "basic theory" about anything exists on our planet, and the planets around earth ( for the last 5000 years )
Any DMM can be used in low voltage applications, including no name test leads. Then, you are more concerned with precision and accuracy of measurements.
But I would be very careful once you start using those tools in AC circuits, especially line voltages that can be exposed to high voltage transients.
Fluke's are expensive not just because they are accurate and precise, but because they meet a lot of safety specifications both in their internal factory ISO standards and many standards by various countries, not just the DMM but the leads you use it on.
If you are working in low voltages, a Fluke maybe overkill for most needs.
You are chatting with an European Industrial electrician , who lives far from the countries of Europe ,
that " are or was " Leaders at the construction of Industrial grade tools , at the last 110 years.
So, because I am the final user , I have own or just operate , many of those.
The problem , never was about " the Quality" of them , but always the price.
About Fluke , in my eyes are just another one player, on the table .
The past decade , was moving on the right track , as it was offering to the technicians ,
instruments with transparent support " Service info & fix it your self " and parts .
Something that other opponents was not offer publicly .
The last decade , they look to have " change their tactics " , now they sing a new song called as " send it to Fluke " ...
This new song , are identical with all the others , boring and with no value .
I agree that the American continent , needs to have their own heroes , even as Industrial grade manufacturers , in that matter I do not argue , and I agree .
But in worldwide level , you must have the " something more" , the "something special" ,
so to gain world wide respect .
Especially if you sell , almost identical products with all the others .
And now I will brag a bit about the Metrawatt ..
Have you ever see , protection relay's in a multimeter ?
LOL ..
Best regards .. my friend ..
