Conditions :(23 ± 5)℃, demagnetized before measurement.

Accuracy: 1%~2% deviation will occur according to the way and position of loading the sample in the measuring frame.

Repeatability: put the same specimens in the specified position and keep it from moving, and measure it repeatedly for 10 times. Take the maximum or minimum value of 10 measurements minus the average value divided by the average value, and the maximum value of the two represents repeatability.

Note: [1] The table only gives reference measuring points, and the indexes such as Hm, Jm/Bm, Ps that can be reached by the specimens during actual measure are related to the performance of the material, quality of the specimens, frequency, current, voltage, etc.

Note: [2] B₅ refers to the magnetic flux density value when the magnetic field H is 5 A/m, and the typical measuring points of non-oriented steel are in parentheses.

Note: [3] P_0.1 refers to the specific total loss value when flux B is 0.1T, and the typical measure point for non-oriented steel is in parentheses.

Note: [4] For medium and high frequency measurment, select the corresponding Epstein frame.

Note: [5] When the selected effective excitation power is 1500VA, the magnetic field can reach 30 kA/m with the corresponding Epstein frame.

Note: [6] The uncertainty and repeatability are at typical measuring points, and are related to the performance of the measured material.
