Hi all,
I want to make Multifunction Calibrator for my personal use.
Specification for Calibrator (Measure and Generate both) :-
1) mili Volt Range :- 0 to 100 mv
2) mili Amp Range :- 0 to 24 mA
3) Volt Range :- 0 to 30VDC
4) RTD Sensor
5) Thermocouple Sensor
Calibrator will operate with 4.7V...
thanks for reply,
The current to the resistor will be max 10 ma, and no frequency its going to pure DC max voltage will be 12, ideal volt are 5 volt DC with 1 mA.
Can you suggest any idea.
