4.2.5 Checking the Wiring
Check to see if the 3169-20/21 is correctly connected to the line to
be measured.
• The wiring check function may indicate incorrect connection
even when the actual connection is correct, or vice versa.
Check the vectors and measurements as well.
• The length of a vector is not related to input level. It only indi-
cates the phase relationship.
• A minus sign (-) with the phase angle indicates a lag phase
angle; a plus sign (+) indicates a lead phase angle. The phase
angle is calculated using the phase of the fundamental of the
PLL source (U
1
) as a reference.
• The voltage levels, current levels, and phase angles displayed
on-screen are those of the fundamental component.
