Note: When using a 5000:5 interposing CT, the user needs to remember that displayed currents
are in kA; (see section 2.3 ), the ‘kA’ box can be checked with a marker on the display’s front panel,
making this obvious.
The G/F Trip Level can be called forward by keeping the ‘SHOW TRIP’ pushbutton pressed longer
than 2 seconds. The information remains visible until the pushbutton is released.
Back to G/F Trip Level display. Back to Display Settings. Back to Table 1.
