QBreakdown voltage testing with the WT-8752 sometimes stops partway through. What could be causing this issue?
AThis issue may be caused when discharge noise occurs when the voltage is applied and then enters the instrument via its external I/O interface, causing testing to stop. Take steps to protect the circuit from noise, for example by adding a ferrite core to the external I/O interface, and take care to position it as close to the WT-8753 as possible. If this fails to improve the situation, add ferrite cores to the red and black output cables as well. Those cores should also be positioned as close as possible to the WT-8753.
