Q: Why is my reading not correct on my multimeter when using the Safe Test Point?
A: A reading error occurs when using the Safe Test Point due to the internal high impedance (102KΩ) of the R-3MT itself and the multimeter used to read the values.This compounding impedance has a mathematical reading error that ranges from 2% on 10MΩ multimeters (most common) to 29% on 500kΩ meters. This explanation can be found on our in the following document: High Impedance Technical Note
