What measurement principles do resistance meters use?
When a current I is applied to the object under measurement, a resistance R and the voltage V are generated with the relationship R = V / I. The resistance R can be calculated using this relationship. Resistance meters provide three measurement methods: constant current (CC), which applies a constant current to the sample; constant voltage (CV), which applies a constant voltage to both ends of the sample; and a third that applies the voltage across the combination of the instrument’s output impedance and the series-connected sample. HIOKI resistance meters use the CC method. Super-insulation resistance meters use the CV method, and some LCR meters allow the user to select any of the three methods.
