6.11 Diagnostic
The EZCT diagnostic mode allows the user to view the EZCT excitation voltage (Vx), excitation
current (Ix) outputs and the H input voltage (Vh) simultaneously on the display. This feature
allows the user to trouble shoot a connection problem to a CT or to verify the EZCT excitation
voltage and current readings against external meters.
The EZCT will turn off the excitation output voltage after 1 minute while in this mode.
NOTE
Both pairs of X1 and X2 cables must be connected to the excitation voltage (Vx), and the H1 &
H2 cables must be connected to sense the Vh voltage in order for this mode to work properly.
