USING LENGTH MODE

www.platinumtools.com

Measure Cable Length:

Measures the entire length of a cable as well as the length of individual

wire pair.

NOTE: Using Coax or Network wire mapping remotes while measuring

length will add one to two feet to the length reading due to internal stray

capacitance.

1) Make sure the power is turned OFF.

2) Insert the cable plug into the corresponding receiver on the main

tester (RJ11 jack for voice cables, RJ45 jack for data cables,

F-Connector for video cables).

3) Press the LENGTH/TONE button

to enter Length Mode. The

following icons appear in the

display screen to the right.

 •An“L”iconappearsinthe

right side of the screen.

 •Cablelengthinunitsoffeet

or meters displays in the

bottom of the screen.

 •Theconnectortypelast

selected (voice, data, or

video) displays in the top

of the screen.

 •An“o”symbolbouncesinthelowerleftcornerofthescreento

indicate activity.

NOTE: Measuring cable length is the primary function of the LENGTH/TONE

button. If you hold down the button too long, you will enter Tone Mode.

If you mistakenly enter Tone Mode, simply press the O/ID button and

select the LENGTH/TONE button again to enter Length Mode.

4) Change measurement units. The units can be changed from feet to

meters and back again by quickly pressing the VOICE and VIDEO buttons

at the same time. When the unit of measurement is set to feet, the “ft”

icon is displayed in the lower right corner of the screen. When meters

are selected, the unit of measurement is not displayed.

5) Verify the connector type appearing in the display screen matches

the connected cable. If it does not match, press the cable type button

corresponding to the cable you plan to measure (voice, video, or data).

NOTE: If you do not select the cable test mode matching the connected

cable, the tester will try to measure the previously tested cable and

may skew the measured length results.

6) Measure Entire Cable: After selecting the cable type button for the

connected cable, the measured length reading shown in the display

screen is representative of the entire cable.

NOTE: Voice and Video length modes automatically select and display

the length of the ﬁrst pin pair without a fault. For cables with no faults,

the length of pair 1-2 for Data Mode and pair 3-4 for Voice Mode will

automatically appear in the display screen.

The Tester Pin # ﬁeld is blank when the length reading for the entire

cable is displayed. Refer to Step 7 below for instructions on stepping

through the wire pairs. Refer to the LCD Display Screen section for a

description of the Tester Pin # ﬁeld.

7) Measure Pin Pairs: Press the cable type button again to measure

the length of the ﬁrst pin pair. The number(s) for the pair being

measured will display in the screen (see Figure 14). Subsequent

presses of the cable type button will cycle through all the pairs and

return to the length reading for the entire cable when you have

advanced past the last pin pair. The following icons appear in the

display screen below:

 •Thecabletypeicon

appears at the top of

the screen.

 •Lengthofpinpairsin

units of feet or meters

displays in lower right

corner of the screen.

 •The“L”icondisplays

indicating you are in

Length Mode.

 •Abouncingballactivity

indicator appears in the

lower left corner.

NOTE: If the selected cable

pair is shorted, “SHORT” will display for the shorted pair and the

length readout is dashes.

8) Interpret display results and trouble-shoot potential cable faults.

View the Lenght Constant:

1) While in Length Mode, press the LENGTH/TONE button again to

view the length constant. The following occurs in the display

screen below.

 •The“L”iconchangesto

“C” indicating the length

constant is being

displayed.

 •Theconnectortype

(voice, data, or video)

appears in the top

of the screen.

 •Thelengthconstant,

measured in picofarads

per unit length,

displays in the bottom

of the screen.

NOTE: Each press of the LENGTH/TONE button toggles between

displaying the measured cable length and the length constant. After a

few seconds the display screen defaults back to the measured length.
