DC Ammeter 500mA
In article ,
says...
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?
...
Well, I remembered having a resistor collection so found a 100 ohm that
measured right at 100.0 and made a shunt lead...worked like a champ.
Discovered the 'ON' current was _way_ too hot on the new controllers as
they come shipped; the ramp function has no chance against it. Backed
'em off to factory spec of 300 mA Lo and 550-600 mA Hi and then, instead
of a bucking bronco, one has a pleasant ride!
Glad you got the current measured.
My fluke meter tops out at less than 1 amp on the ma scale, but on the
10 amp scale it will show down to 1 ma of resolution.
