I need to mount a digital panel meter in a small enclosure and use it to monitor the voltage and amperage that a pc board in the enclosure is producing.
The item I am making is a 4-20 0-10 volt power source used to test and check various actuators, sensors etc....
Its basically a small power supply.
Anyhow I am using a switch to switch the output from 0-10v out to 4-20ma out and vice versa.....
I can fiqure out how to monitor the voltage but I get stuck when trying to fiqure a way to monitor the current.
Does anyone have a circuit for a multimeter using a panel meter that will do both volts and amps.
I know there used to be some multimeter on a chip schematics out on the net before but I cant seem to find them now....dont even have a clue as to the chip number.....
If someone could talk me thru this...or point out a schematic somewhere on the net where I can get some general ideas from I would appreciate it.
thanks
