Opens
This function shows the distance to an ‘open’
(or ‘break’) based on the cable type chosen. The
Opens function is most accurate if other pairs in
the cable are active. If other pairs are not active,
you must short at least 30% of the other pairs to
the cable shield.
Press the [Up] or [Down] keys to move to a
desired cable type. Press the [Enter] key to
accept the choice and return to the main Opens
screen. Press the [Back] key to return without
changing the cable type.
Press the [Tab] key to edit the “Custom” cable
type. Press the [Enter] key to edit the “Calibrated
Cable” type.
The 965DSP-B will first measure the distance to
an open between Red and Black. Press the [Tab]
key to move to the next test lead configuration.
Press the [Setup] key to change the Cable Type,
or to select Capacitance.
