3. APPLICATION & OPERATION
3.1 ‘9 Volt’ battery power & battery tester
The CT2 requires power for operation from a standard 9v battery for operation (battery not included). You can check
battery performance by simply selecting the rotary selector fully clockwise to the ‘Battery Check’ position. If the LED
indicator illuminates you battery has tested OK. If the LED fails to illumintate your battery is drained of power and
requires replacement.

3.2 Battery replacement
There is a well secured battery compartment housed within the CT2 with access provided through a removable
metal compartment cover. The battery compatment cover is secured by two (2) screws. Simply unscrew the battery
compatment cover to gain access to the battery compartment for battery installation or replacement of expired or
power drained batteries.

3.2 General operation proceedure
The basic operation guide for testing cables is to connect one end of your cable to the left hand side connector sock-
ets of the CT2, and the other end of your cable to the right hand side of the CT2. Depending on how many pin to ->
pin cable connections are housed within your currently connected cable, simply turn the rotary dial through each
position and take note of the LED indicators status (on/off). If the selected pin to -> pin connection is OK, the paired
LED’s for the appropriate selection will be illuminated. A failed connection status can be observed by taking note of
non illumated pairs.

For single pin 1 to ->1 connections there are two (2) banana connections on the front panel permanently wired as a
continuity tester with LED and beeper indicators. simply connect each end of your single pin cable to indicate opera-
tional status with an illunminated LED and status beep.
