PROBLEM TO BE SOLVED: To measure a grounding resistance without stopping power supply. SOLUTION: A superimposing current transformer 14 for superimposing an alternating voltage and a current value detecting current transformer 7 are inserted and arranged in a measuring object grounding conductor, and a...
The definition of the insulation resistance test is the test that is used to measure the total resistance between any two points that are separated by electrical insulation. This test may be defined as the test that is used to measure the resistance between any two sites. The name “megger...
Having said all that, in this case this is a standard problem and there are simple pre-packaged solutions. You install a low-value shunt resistor in the supply (people often prefer to use the +ve supply) and use a specialized amplifier to measure the voltage ...
Attenuated probes are great for improving accuracy at high frequencies, but they will alsoreduce the amplitudeof your signal. If you’re trying to measure a very low-voltage signal, you may have to go with a 1X probe. You may also need to select a setting on your scope to tell it you...

A query was put on PF and the following explanation was obtained from PF user@TomG: You mentioned that you used the same meter to measure the current. The Current range of a digital ammeter has some low, non-zero, internal resistance, which would add to your effective load resistance. Ha...
How To Measure Resistance Measure resistors with an analog multimeter It is very easy to read resistance with an analog multimeter or ohmmeter. You can read the resistance of variable resisistors (also known as potentiometers or POTS) and standard resistors. A variable resistor can be tuned fro...
Power-Supply Rejection:PSR, expressed in decibels, is a measure of how well the LDO rejects ripple from the input power supply over a wide frequency range (1 kHz to 100 kHz). In an LDO, PSR can be characterized in two frequency bands. Band 1 is from dc to the control loop’s unity...
