Electronic Circuit Design

Hi, I am trying to build this mV source that you have drawn on your site. It requires a 5vdc power source with a 1k resistor in line with a 10K pot. Your schematic shows also with the pot a 10k resistor and a 100E component which I have no idea what… more »

My application is to calibrate some instruments with help of this source. I've studied your circuit earlier also., but I want a battery operated mV source. upto 100mV full scale which is portable but still very accurate. The better the accuracy more… more »

I was looking for a simple MILLIVOLT SOURCE for ion electrode testing and came across your pdf schematic. This design would appear to fit my needs perfectly, but I have a couple minor questions that I hope you could provide answers for: The pdf drawing… more »

Subject: delabs comments - Tell Me. message: why 4-20mA standard. why not 2-22mA or any thing else Mail from MU they knew you would come up with a question like this. so see this page 4-20mA Current Loop Primer and also Intrinsic Safety… more »
