VDV SCOUT

PRO 2 LT – DISPLAYING LENGTH CONSTANT

Assure the tester is off

and the screen is blank.

Press the length button

to enter length mode.

Press the length button

again.

The length constant will be displayed

on the screen for three seconds.

VDV SCOUT

PRO 2 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 2 LT stores a separate length constant for each of the three cable types (voice, data, and video).

Follow the procedure in

MEASURING LENGTH

section

MEASURING LENGTH

section

MEASURING LENGTH

to set up the correct type of cable.

Press and hold the length button

for three seconds until EDIT CAP is shown

on the screen.

Press the Up Arrow

and Down 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.

Press the length button

again

to return to length measurement.

VDV SCOUT

PRO 2 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 50 ft. or greater.

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).

Follow the procedure in

MEASURING LENGTH

section

MEASURING LENGTH

section

MEASURING LENGTH

to set up the cable to be tested.

Press and hold the length button

for three seconds until EDIT CAP is shown

on the screen.

Press the Up Arrow

and Down Arrow

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.

Press the length button

again to return to

length measurement.

You may now measure

other unknown lengths of cable.

VDV SCOUT

PRO 2 LT – CHANGING UNIT OF MEASUREMENT

Assure the tester is off

and the screen is blank.

Press the length button

to enter length mode.

Press the phone button

and video button

at the same time.

The screen will show "METERS" or "Ft." momentarily, then

show the length measurement in the unit selected.

Note:

Ft. 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.

Length Constant = 15.0pF/ft.

Length Constant Display Mode

Length Constant = 15.0pF/ft.

Length Constant Edit Mode

Measured Length = 86 ft.
