Appendix A
Changing the battery
Changing batteries:
First loosen the two bottom screws in the bottom bumper. Pull the
bumper downward.
The four AA batteries are in a holder. Remove the old batteries and
replace them with new batteries. Note the polarity. Do not combine new
and old batteries. Always use batteries of the same type and date of
manufacture.
Return old batteries to the supplier or a recycling facility.
Test settings
Cable definitions (Main menu>Setup>Test setups>Cable definition)
You can enter the different types of cables used. The types which already
have been entered can also be overwritten.
After selecting the cable type to be changed or the last position without
an entry, select it by pressing SEL. The display shows "Name:". You can
enter a unique cable name. Fifteen characters are available. At the
flashing cursor position, press the ▲ and ▼ buttons to scroll through the
alphabet and the numbers 0-9 including a space. Select the character or
number at the cursor position by pressing SEL. Once the name is
entered, confirm it by pressing SEL. The following appears:
"Velocity
: xx%“. This is the percentage velocity of propagation (VP) in the
cable in relation to the speed of light. Enter either the value indicated by
the cable manufacturer, the previously determined value, or an
approximate value. The value is approximately 64
– 68 for telephone and
Cat3 cables, approximately 72 for Cat5/6, and approximately 77 for
Cat6/7.
Note that the cable lengths can only be correctly measured when
the VP is correct.
After entering the VP value, save it by pressing SEL. This allows you to
quickly and easily predefine the cable types that are being used.
Wiring definitions (Main menu>Setup>Test setups>Wiring definition)
You can add to the wiring versions used.
E.g., “568B UTP”.
It is helpful if you write down the pin/pair assignment of the wiring version
to be created.
