AUTOTEST OVERVIEW
Wavelength selection mode
If the required regular testing uses fewer wavelengths than the
instrument has available, then it may be convenient to reduce the
number of active Autotest wavelengths. For example, instead of the
source rotating through 1310 / 1490 / 1550 / 1610 nm, it can be set to
test at 1310/1550 nm only.
To switch wavelengths on/off:
•
press [SOURCE] and then [-/+] to select wavelength.
•
to check whether selected wavelength is switched on/off,
press right hand button below the screen, its status will be
indicated as ‘IN’ or ‘OUT’.
•
on hidden keypad, press [  ] till ‘Shift’ symbol comes on LCD,
then right hand button below the screen to change status of
selected wavelength.
Autotest operates only with wavelengths selected as ‘IN’.
Selected settings will be retained at the next turn on.
User to user communication
This is only applicable when a pair of Two Way Loss Test Sets are
used. Display update for both instruments can be started or stopped
from either instrument by pressing [HOLD] button, which also activates
the buzzer at each end. Once on, ‘HOLD’ symbol will flash on LCD. It
allows handy communication method between two users, so they can
synchronise while working through successive fibers, see related

Practical uses in the field
➊
Press
[HOLD] button
on unit.
➋
Unit beeps
twice, ‘HOLD’
symbol blinks.
After recording or saving test data
for exi
sting fiber, “near - end” user
do this to signal “far -end ” user to
move on to next fiber.
➍
Unit beeps
once, ‘HOLD’
symbol stops
blinking.
➌
Press
[HOLD] button
on unit.
After reconnecting meter with the
next fiber, “far -end ” user do this to
signal “near -end ” user to record or
save test data.
This communication function is also linked with KITS ™ software, so
that the far end user knows when a reading has been saved in KITS ™ ,
and the near end user knows when the far end user has moved to the
next fiber, and so is ready for the next reading. Refer to KITS

user
manual for detailed operating instructions.
Note: all operation and data acquisition can be controlled from one
end only.
