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.
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 [Enter] to accept the changes and return to the Opens Setup screen. Press [Return] to return without making changes.
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.
