10. Calibration

To maintain the performance of the MM-315B, it is necessary to calibrate it periodically.
The calibration is carried out at our factory. Send us your toroidal coil along with the
MM-315B for calibration. As the conditions of degradation for the MM-315B differ
depending on the operation environment, it is necessary to calibrate the toroidal coil and
the MM-315B together.
Contact Amada Miyachi Co., Ltd. for details on calibration.
