Using the DC1000A DC Current Bias Supply with Handheld meters
We have already shown how the DC1000 can be used with our own AT Testers and all industry standard LCR meters to extend the scope of your magnetics quality testing.
Customers should also be aware that the same principles will still work with simpler, cheaper handheld meters where accuracy has been deliberately traded for a more cost effective testing solution.
Worked Example
In this example, we have tested a COILCRAFT inductor, (PCV-2-564-08L - Inductor, 560 µH, 7A)
The measurements were performed using a Keysight U1733C Handheld LCR meter to record the series inductance as we apply varying DC Bias provided by the DC1000A. (0-20A in 1A steps)
The results were plotted below.
We can see that the inductance holds up under DC bias above the published specified 7 Amps, and in fact only exceeds spec at around 12 Amps
