3. Application

☆ Calibrate Primary Current I, Magnetic Flux Φ

TH8020 Soft Magnetic Material DC Magnetic Meter Calibration System TUNKIA

• Calibrate primary current I: TH8020 has a built-in precision current standard meter, which can calibrate the current output of the magnetic meter being calibrated.

• Calibrating magnetic flux Φ: TH8020 has a built-in precision volt-second generator, which can calibrate the flux meter of the magnetic meter being calibrated.

☆ Calibrate Magnetic Characteristic Parameters

TH8020 Soft Magnetic Material DC Magnetic Meter Calibration System TUNKIA

• Use the reference specimen as the load, set the calibration point through the magnetometer to be calibrated, and output the excitation current.

• Use TH8020 to simultaneously measure the saturation magnetic flux density Bs, remanence Br, coercivity Hc, maximum magnetic permeability am, and initial magnetic permeability μi of the reference specimen with the magnetometer being calibrated to achieve calibration of DC magnetic characteristic parameters.

☆ Calibrating Permeameter/Solenoid Magnetic Field Non-Uniformity

TH8020 Soft Magnetic Material DC Magnetic Meter Calibration System TUNKIA

• Set the excitation current through the magnetometer to be calibrated, so that the solenoid or permeability meter to be calibrated generates a magnetic field.

• Place the probe of the precision magnetometer into the solenoid or permeameter to be calibrated.

• The host controls the intelligent positioning device of the probe to move the probe slowly to measure the magnetic field non-uniformity of the permeameter/solenoid
