Effect of the DC1000 on Inductance Readings

The affect the DC1000 has on an inductance reading is dependant on the test Voltage and frequency.

Fig. 17 should be used to determine the affect for a particular test.

DC1000 Error Current


Fig. 23

Example:

Measuring the inductance of a 2μH inductor at 0.2V, 100kHz:

Z = 1.2566Ω
@ 0.2V, i = 159.155mA
From fig. 23, the error current = 0.45μA/mV @ 100kHz
Which, for a signal of 0.2V = 90μA
Error in measurement = 90μA / 159.155mA = 0.057%
