thanks for that. i found
a post on why to avoid the HOPI units, but doesn't state which to use instead.

tried to ask there, but they are rejecting new users. it's a shame, because i like the HOPI display better than other meters i've seen.
are the ZHURUI meters any more accurate? there is also no included 'deathdapter'.

i see UNI-T makes a meter, but the display is a bit limited.
