Data sheet for enclosure/chassis leakage current
Table 4-10 shows a typical format for recording the enclosure/
chassis leakage current. Measurements should be recorded 
from multiple locations for each set of test conditions. The actual 
location of the test probe may vary by Ultrasound system.
Record all data in the Electrical safety tests log.
NOTE:  Not all test procedures are applicable to all areas of the world. 
Reversed Polarity testing content satisfies regions following IEC 
62353:2007 and IEC 60601-1:2005. 
NOTE:  Values in italics font are given as examples only.
