Simple Millivolt Source for Calibration
This is a modification of a mV Source that can be whipped up easily. You could use a DPM or Multimeter to read the output. The ability of this circuit to perform well depends...
Significance of Current Loop 4 to 20 mA Standard
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...
Building a mV Milli-Volt Calibrator Source
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...
Millivolt Source with Digital Potentiometer
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. It could be a...
Millivolt Source – Field Calibration Current Loop
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 Ib error as gain is...
Simple Battery Characterizer
I was reading about some IC’s from Maxim/ Dallas saying ” Simple battery characterizer” for plotting a charging/ discharging cycles & graphs are available on computer for study I want to plot an extensive...
Millivolt Circuit ICL7129 MAX7129
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...
