A look at the Uni-T UT210E

<< < (114/177) > >>

stj:
no, both chips are 10,000 count, but the 0660 AC RMS calculations fail after about 7000 counts - the 1106 chip this was fixed/improved.
every function other than AC-volts can run at 10,000 on either chip.

What if I have a meter that is the older chip but not TRMS, can I just jack it up to 10,000 count?

For example, this meter http://a.co/blshU3d

I've recently flashed it with some of the mods but stopped at 8000 count because of the AC readings bug, I didn't even realize it only affected TRMS AC readings.

stj:
the 0660 is always true-rms, it's an internal function of the chip.

Why would they advertise it as not being TRMS then?  Don't you need a secondary chip to do that?

stj:
no, there are only 2 chips, the main one and the eeprom with the config.
and for clamp meters, one or 2 op-amps for the clamp.
