I posted a month or so ago about fixing up butchered wiring on choke
circuit for old JLG 40H manlift -- got it going and on to next step...

Have had to replace a couple of the function controllers (swing/lift)
which have builtin ramp circuitry to avoid "bang-bang" operation.

Unfortunately, the new ones are never tuned to the machine and to do so
require measuring current and adjusting the hi/lo/ramp pots per a set of
ranging operation of the controller.

The current range is from 500mA to ~1A DC; my Fluke and other
multimeters are limited to 300/400 mA on the ranging scale or 10A full
scale. Unfortunately, the 10A range doesn't scale so is only 1 digit
precision which isn't sufficient to adjust...

So, question is, does anybody know of reasonably-priced DMM that has
such a current range?

I have a Tek multifunction scope DMM plugin module that is good range
but it's corded and bulky and not terribly convenient to put in the lift
bucket because final adjustments require moving the controls while
operating so the corded operation is a real hassle...
