WX Warning
To prevent electrical shock, remove the null
post adapter from the ∅/Null jack after a test
lead zero is performed. The ∅/Null jack
becomes potentially hazardous during some
of the test conditions.
A low resistance measurement is necessary to make sure
there is a good ground connection through the power
cord. Refer to the applicable electrical safety standard for
the specified limit value to be followed.
Figure 11 shows the electrical connections between the
Product and the DUT. Table 4 is a list of the abbreviations
used in the schematics and their descriptions.
