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 likeRead More
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 aRead More
Variable Parameters like voltage, current can be obtained by using a Digital Potentiometer. Microcontrollers or Counters operate FET CMOS Analog Switches. The switches configure resistor networks to adjust circuit performance.Read More
This is easy to rig millivolt source for field calibration or troubleshooting of 4-20 mA current loops. Here a Darlington pair is used for current amplification which reduces the IbRead 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 scaleRead 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 haveRead More
