Note 1: Occupational/controlled exposure limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Note 2: General population/uncontrolled exposure limits apply in situations in which the general public may be exposed, or in which persons who are exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure.

TEST REPORT

Report No.: MTi250321005-0102E2

Note: tips mode of the test probe is used for 0cm measurement.

5.3 Test Procedures

a. H-field measurements should be taken 0 cm ~ 20 cm with 2 cm increments from the center of the probe.

The center of the probe to the tip surface of the probe is 18.5 mm, so the directly testing can be performed at the probe center from 2 cm to 20 cm.

To measure the 0 cm H-filed, the probe tip mode is used. The total H-field at the tip-surface Htip-surface can be extrapolated using the total H-field measured at the top and bottom sensors, Htop and Hbottom, as well as the normalized H-field gradient Gn. The field extrapolation formula is a polynomial function of Gn (d = 18.5 mm)

+  2
