[LT] LENGTH CONSTANT EDIT MODE
Follow these instructions to set the length constant based on a known value (for example, as given by the cable manufacturer).
The VDV Scout™ Pro LT stores a separate length constant for each of the three cable types (voice, data, and video).
1. Follow the procedure in MEASURING LENGTH section to set up the correct type of cable.
2. Press and hold the length button

for three seconds until EDIT CAP is shown on the screen.
3. Press the Up Arrow

to increment or decrement the length constant in units of 0.1pF to the desired
value. The screen will switch back and forth between the length measurement and the length constant value every two
seconds while no buttons are pressed.

[LT] DETERMINING LENGTH CONSTANT
Follow these instructions to set the length constant based on a sample cable of known length. For best accuracy,
the sample cable should be 50ft or greater.
1. Cut or obtain a length of cable of the same type you would like to measure. Measure the cable using standard methods
(pad printing on the cable or a tape measure).
2. Follow the procedure in MEASURING LENGTH section to set up the cable to be tested.
3. Press and hold the length button
I
for three seconds until EDIT CAP is shown on the screen.
4. Press the Up Arrow
F
and Down Arrow
G
to increment or decrement the length constant in units of 0.1pF. The screen will
switch back and forth between the length measurement and the length constant value every two seconds while no buttons are
pressed. Press the arrows until the length measurement is the same as the value measured earlier. The length constant can
still be changed while the length measurement is being viewed in this mode.
5. Press the length button
I
again to return to length measurement. You may now measure other unknown
lengths of cable.

at the same time. The screen will show "METERS" or "FEET" momentarily,
then show the length measurement in the unit selected.
Note: Feet unit readings have no decimal place and are displayed as "0 Ft". Meters unit readings have one decimal place and are displayed
"0_0" for 0.0 meters. Length constants are displayed in pF/ft or pF/m depending on the selected unit measurement mode.
