Automatic Coil Test System

General-purpose instruments

We are developing and marketing Coil Testers, LM Series to test electrical properties of coils in a nondestructive method.


Models in LM-2100 series equipped with LCR meter are designed to measure inductance and dissipation factor of the coil to which DC current is superimposed.  Special circuit is built in to protect the LCR meter from surge voltage.  Applied current can be step by step in the remote mode.  Voltage application is impossible with the safety cover open.
