UT210E Problem measuring AMPS!!! :(
CDaniel:
If you find an old CRT tv or monitor you can use the degaussing coil ... you can google easily for details , far more common than a tape eraser . And pretty powerful .

Hi cdev ... sounds smart solution... but can you give more details? Nails? what transformer to use i have for eg a 220v 12v from battery charger.... what cable and how many turns would you use...after that is clear.. would you pass them close trough the clamp or meant wrap the jaws or do turns like if you were measuring current.. im talking about DC measurementes.
Yes the device my UT210E works perfect in all other functions that is why im so interested in its rescue.
Yes im not gonna opem to touch trimpots nor update firmware wich would be great though.
Joe yo know too much and showed your knowledge.. but from point of view of myself as an user i wanted just my device working at least on +- 100mah error and would be more than happy i bet with your device could be achieved.

This is a clamp meter with a 2.5% +/-5 digits spec, so you will only achieve +/- 0.1A accuracy at low amperage (like below 4A). So temper your expectation on what this meter can really deliver in terms of accuracy. Due to its design, it is hard to achieve the 0.1A accuracy in clamp meters throughout its measurement range even for expensive meters, let alone a $10 Uni-T.

It has 2A range.. 2.5% +/-5 is +/-5mA+/-5d max error..
EDIT: It has 2A range.. 2.5% +/-5 is +/-50mA+/-5d max error.. stupid me, it's been a long day.....

I'm going to say It has 2A range.. 2.5% +/-5 is +/-50mA +/-5d or +/-55mA. Maybe we can vote on it and see who's right. :-DD
