Hi all could someone explain what a ramp test is and how they are carried out, ive heard the term but not really sure what it is,

Thanks a lot

mine's an alphatek, has a 1mA resolution. does for me.

Think you'll find it's much better than that Tel, more like 0.100mA or better

Declared specs are only:

DC Current: Range 2A Resolution 1mA +/- 2.8%
DC Current: Range 80A Resolution 100mA +/- 3%
AC Current: Range 2A Resolution 1mA +/- 3%
AC Current Range: 80A Resolution 100mA +/- 3%

Non Contact Voltage 100VAC to 600VAC 50/60Hz

What's the model number of the alphatek, maybe i'm looking at the wrong model number?? I thought Tel had the Alphatek TEK775... That model has a 0.1mA resolution on the low 200mA range...

Yeah well i1m in havin me tea resolution just now....then i will be "in"....tee hee......:sorcerer:

The one Tel has is the 633 (same as my old one), not made anymore mate.

 

[GLENNSPARK]

Well my MFT says 1997 someware in the manual for it...but it just keeps goin and goin and goin..........

 

[GLENNSPARK]

I think n all what i should have said at the start of this thread is 0.5mA...not 5ma...dohhh

Ah, ...OK, my mistake then...lol!!!

Want a current clamp for my MFT....but itl have to wait...savin for part p assessment then we`l see ...chauvin arnoux are about 15 mins walk from where i live so..........
