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.

Sorry to thread jack, but I'd like to ask a follow up to this statement. Any guesstimate of fully charged amp acceptance for pair of 6V flooded at a 14.8V (temp corrected) absorption setpoint? My PWM controller uses time at or below a percent duty cycle for the absorption to float transition and it seems like I could use this info to make a meaningful full SOC transition to float.
I'm using 3A at 14.8V for ~400Ah, four GC2s.
3A tells the solar charger to switch to float.
IOW my batteries are sitting at 14.8V a lot longer than most folks. And when we're using Amps, the batteries can take all day to get there, or not. Of course at night, they can rest (settling down to 12.x depending upon what we're doing).
Only check and fill the water twice a year. And I do equalize after a particularly long and brutal period of cold, grey skies, furnace usage and incomplete charges, when Sol lets me.
Think I do this (14.8V down to 3A) because of Mex's "Top Charge" diatribe. Don't have a charger or power supply that can do top charging, so this is my approximation?
