Page 35: Calibration
MM-315B 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.
