Not a TriMetric, but for $20 might be worth trying out...
Bayite DC 6.5V-100V Digital ammeter voltmeter Amazon suggested this for me and I'm thinking for $20 I might just give it a try. Has very good reviews too.

Pianotuna, exactly right.
Larger shunts naturally widen the resolution band. The + - % error yadda.
The BORG has a pair of 50 ampere shunts. One digital the other analog 50-amp capacity. Kinda wish I waited and used an amp hour meter or better yet a kWh meter.
I am chasing down a USB input, A to D converter with kWh graph plotting. Expandable scale one minute resolution of all three components, amperage, voltage, and ampere hour accumulations. PC powered analysis. I am not sure what software program they use. It's of Indian / Malaysian origin. I like the minute by minute data points. Bi-directional polarity
