Press [Enter] to accept the changes and return to the
Opens Setup screen. Press [Return] to return without
making changes.
First enter the red to black capacitance per unit
distance using the blue keys. This is also called
“Mutual” capacitance.
Then press [Tab] and use the blue keys to enter
the capacitance/distance for black to green. This
capacitance is sometimes called the “Pair to
Shield” or “Pair to Ground” capacitance.
Press the [Tab] key to edit the “Custom” cable type.
Press the [Setup] key to edit the “Calibrated Cable”
type.
Edit Custom
Use this function to change the value of the “Custom
Cable” type. Select Custom Cable if you are using a
specific type of special cable on a regular basis.
Calibrate to Cable
Use this function to measure the capacitance of a
known good pair within a cable of known length.
This value can be used as a ‘Calibrated Cable’ (or
‘reference’) to find the distance to an ‘open’ on the
same or similar cable.
Connect the red and black leads to the pair (to be
used as a reference) and green to shield.
