Current Source for Resistance Measurement
Here is a current source you can build for resistance measurement. When the current is held constant, you know as per Ohm’s Law the Voltage across Resistor is proportional to Resistance value. The supply...

Ohmmeter – Simple Resistance Measurement
Measurement of resistor values in circuit configurations are required to be made often, as these might have changed in value due to various tolerance ranges, and hence could be the cause of faults. Likewise...
Ammeter and Precision Rectifier
Studying current measurement is a prerequisite for many of the measuring techniques. The current parameter mainly specifies the power consumption in a circuit, given the value of resistance. It is found convenient to measure...
Up-Down counter-timer
(A question answer thread of delabs.net, nearly a decade old) Presettable Up-Down counter-timer I am looking for a schematic for a pre settable Up/Down counter that I can build for my church. It needs...
Temperature Meters with Analog Recorder Output
I would like to know if you offer a monitoring solution that will constantly measure ambient (air) temperature (say, 0 to 150°F), and provide a corresponding DC voltage output of either 100 mV, 1...
HV low current device for testing
New device and needed E-instrumentation > > Have you a controlled e.g. 0-10 kV and 0-100 mA device MR EU Do you mean a Variable 0-10 kV with 0-100 mA Current Variation. Yes, i...
