INTRODUCTION AND APPLICATIONS
The KI 9000A Series Optical Power Meter and Optical Light Source
offer both ease of use and superb measurement confidence. They are
very convenient to use, and have reduced cost of ownership.
This equipment can be effectively used by installers, technicians and
engineers to test all types of fiber optic systems in various applications
including SMF, MMF, POF, PCS and ribbon fiber:
Tx / Rx absolute power levels in dBm
Optical loss in dB
Continuity testing with the versatile test tone features
The interchangeable optical connectors are drop and dust protected
by a snap on cover. A wide variety of connector styles are available.
The instruments feature a tough polycarbonate housing with shock
absorbent sides and corners, which has passed extensive drop
testing.
Calibration can be performed by any suitably equipped laboratory. The
recommended re-calibration cycle is 3 years.
Power Meter features
The standard power meters work with fiber core diameter up to 200
micron, with both PC and APC polish connectors.
Large area detector power meters work with fibers with up to 3 mm
active area including MPO/ MTP connectors with up to 72 fibers.
Detector options include Germanium (Ge), Indium Gallium Arsenide
(InGaAs), Silicon (Si), high power, large area and wavelength
selective.
Power meter calibration options are available from 470 nm to 1625 nm
with specified accuracy at power levels from +24 to - 60 dBm.
The display shows dBm, dB and linear units, and display hold is useful
for data recording.
Superior measurement confidence is achieved with a unique Total
Uncertainty Specification, which covers the full temperature,
measurement and connector range. A calibration certificate is
supplied.
The sensitive optical tone detector displays the actual measured tone
frequency in Hz. If a standard tone is detected, the buzzer sounds,
which is useful for fiber identification and continuity testing. MultiFiber
ID (new to A series) can also separately identify any of 12 test tones
from a compatible source, greatly speeding up continuity / polarity
testing.
Power stability testing is easily using the max/min recording function.
TamperLock mode (new to A series) is a useful way to lock the
instrument features to enforce pre-set & error free operation.
TamperLock operation is auditable and can be defeated on-site if
needed.
Slow Mode (new to A series) can be used to increase signal averaging
for noisy signals.

INTRODUCTION AND APPLICATIONS
Light Source features
Multiple wavelength sources have 1 - 3 switchable wavelengths
through one port, which makes operation faster.
Laser sources at 1490 / 1310 / 1550 / 1625 nm are used for testing
single mode fiber systems. Laser source power levels can be adjusted
3 dB by the user in 0.1 dB increments.
LED sources at 850 / 1300 nm used for testing multimode fiber
systems.
The 1300 nm LED source can also perform moderate distance single
mode testing.
The 660 nm LED source option is ideal for POF testing in combination
with KI9600 XL power meters.
VFL laser sources at 635 and 650 nm have some specific advantages
compared to common VFL pens such as: improved eye safety when
no fiber is attached, replaceable through connector, proper connector
interface which won’t damage connectors by rotation, APC interface
option, proper interchangeable connector adaptors, wider variety of
laser options, tone options that work with a clip-on fiber identifier
Light sources have re-connection repeatability of 0.1dB. Combined
with the instrument excellent stability, this provides more accurate
measurement results and improved test confidence.
TamperLock mode is a useful way to lock & pre-set the instrument
features to simplify operation. TamperLock operation is auditable and
can be defeated if needed.
AutoTest can be used with a suitable Autotest compatible power meter
such as the KI2600 series (not the KI9600 series) to synchronise the
power meter and light source wavelengths and other parameters.
A multiFiber ID feature (new to A series) provides easy multi-fiber
identification of up to 12 fibers at a time. To use this feature, multiple
light sources are set up on multiple fibers, with each one set to a
different tone. When a tone is detected by a power meter, a buzzer
sounds and the corresponding fiber ID number is displayed.

extremes that may cause condensation within it.
Safety
This instrument contains no hazardous optical or electrical items.
When using this equipment, optical safety precautions should be
observed commensurate with the maximum available source power,
since most of this power can also be coupled out of the instrument.
WARNING! Observe optical safety when using high power.
Optical safety requirements at high power levels MUST be observed
or eye damage is likely. Organisations and users operating optical
equipment with these power levels MUST determine and observe
relevant safety precautions, which are beyond the scope of this
manual.
Never look into the end of an optical cable or connector which might
be attached to an active source.
Do not enable a laser when there is no fibre attached to the optical
output connector.
Optical magnifying instruments (e.g. microscope) increase eye hazard
unless they contain suitable optical attenuating filters. Disconnect the
source before using an optical magnifier.
The laser module has a built-in safety circuitry which will disable the
optical output in the case of a fault condition, however, this cannot be
guaranteed.
An equipment assurance program is recommended to check for safe
laser operation.

BATTERY POWER
These instruments are powered by two 1.5 V dry alkaline ‘AAA’ size
batteries. Alternatively, use re-chargeable NiCad or NiMH batteries:
Model
Battery run time in hours
KI 9600 Optical Power Meter
300
KI 9800 Optical Light Source
Laser/LED source: 40/35 hours in
Autotest, typical
When the batteries are low, the low battery indicator is shown on the
display. At this stage, there is approximately enough energy for
another 20 hours of use.
To save energy, the instrument automatically turns off after 10 minutes
without operation.
To change the batteries, open the cover of the battery compartment at
the side of the instrument, remove the batteries and insert new ones.
When an instrument is put away for storage, it is good practice to
remove batteries to prevent the possibility of battery acid leakage
damaging the equipment.
CAUTION!
Do not use lithium batteries or other batteries with a nominal voltage
greater than 1.8 V. The instrument may be damaged.
Protect our environment! Batteries purchased from Kingfisher agents
can be returned to them for appropriate disposal.

OPTICAL CONNECTOR
Light Source and Standard Power Meter
To access the optical connector, grasp the top left corner of the
instrument, and pull off the cover.
To install an adaptor, align the locating slot on the side of the through
adaptor with that on the instrument connector, and press it on.
To remove an adaptor, press button on the front of the instrument and
then pull off the adaptor. It is easier to pull off the adaptor with a test
lead in place, since this gives better grip.
Different styles of connector adaptor (ST, SC, FC, MU, LC/F3000,
E2000/LSH, D4, MU, 2.5mm universal, SMA and LSA/DIN) can be
easily fitted by the user.
CAUTION! When not in use, keep the test port and connector covered.
Do not touch connector tip with your fingers, since body oils and dirt
can impair connector performance.
The supplied standard adaptors have ceramic sleeves and do not
cause metal dust contamination, which can cause connector failure
and fiber fuse at very high power levels.
CAUTION! Do not use damaged or incompatible connectors.
CAUTION! When using bare fiber adaptors, do not scratch the
detector lens with a glass fiber end.
Power Meter
Power meter can be used with both PC and APC connector styles.
Bare fiber adaptors must achieve fiber eccentricity of ± 100 microns,
and end tolerance of ± 300 microns relative to the ferrule end.
Preferred bare fiber adaptors consist of a connector with fiber retention
device or other end stop.
For regular work with bare fibers, it is preferable to use an alternative
arrangement such as a multimode pigtail with a v-groove or
mechanical splice.
Large Area Power Meter
Power meters with a large area .detector do not have a snap-on dust
cover, and may not have any connector fitted as delivered.
The threaded connector adaptor is easily installed or removed by
rotating the adaptor. For model, KI9600XL-Ge7, when fitting an MPO
connector adaptor, continue rotating the adaptor clockwise until a
“click” is felt. At this point the adaptor is rotationally aligned with the
rectangular detector chip on power meter.
CAUTION!It is suggested to always leave a connector adaptor in
place to physically protect the detector.
Note these adaptors are usually metallic, so if they are used on high
power systems, extra cleaning of the connector after insertion into the
adaptor is advisable.
A light source is either PC or APC connector specific. This is
determined when ordering the instrument.

KI 9000 UM-10

OPTICAL CONNECTOR
CAUTION! The use of bare fiber adaptors is not recommended as
permanent instrument damage will occur.
How to clean the optical connectors
Always clean the mating connector tip and ferrule before mating, using
approved materials.
CAUTION! Do not attempt to clean an optical interface with anything
hard that could scratch glass, or permanent instrument damage may
occur.
Power Meter
The glass power meter interface does not make contact with the
inserted connector - there is a slight air gap. Therefore it will not wear,
and only needs occasional cleaning.
To clean, first remove the connector adaptor to access the glass
interface, then use a soft brush, alcohol, air can or sticky material such
as ‘Blu tac’ to remove dirt.
Large Area Power Meter
The window on the large area detector is delicate and should not be
scratched, pushed or banged.
Light Source
To clean the interface, use stick style connector cleaner and blow
away any dust or dirt with compressed air.
If this is not sufficient, clean the interface by rubbing a lint-free lens
cloth over the surface using small circular movements
WARNING! Disable source when cleaning optical interface. Remove
batteries before using a microscope to inspect instrument connector.

OPERATION: Power Meter
WARNING! Observe optical safety procedures relevant to the power
levels being measured.
To switch on KI 9600 instrument for permanent operation, press and
hold [POWER] during turn-on. ‘Perm’ on the display indicates that the
unit will stay on permanently. Also during instrument turn on:
-to view all display segments, press and hold down []
-to display firmware version, press and hold down [HOLD]
-for quiet non-beeping operation, press and hold down []
Should the instrument fail to turn on, the microprocessor may need re-
booting. To do this, remove the batteries for at least 40 seconds.
After turn-on, the instrument performs a self-calibration sequence, and
then displays absolute power in dBm at the previously set wavelength.
If ‘HI’ or ‘LO’ are displayed, the input is out of range.
To measure the operational power level in a fiber optic system, the
meter is used in dBm or linear modes. To measure optical loss or
attenuation, the power meter is used in dB mode, and the source
power is taken as a reference.
To scroll wavelength, press [] or []. The display shows the
nominal wavelength in nm on the top right of the display.
To toggle logarithmic / relative/ linear display modes, press [dB / dBm
/ mW]. The display will show ‘dB’ or ‘dBm’ or ‘nW’.
To stop / start display update, press [Hold]. The symbol will flash when
the display is on hold.
To set reference, press and hold [Set Ref] for more than 3 sec.
When in relative mode, the reference value is displayed on the left
hand side of the display.
To display max min recorded power, press and hold [Max Min]. To re-
set this function, press [POWER].
When a multi-fibre ID tone (1 –12) is detected by a power meter, a
buzzer will sound and the corresponding fiber ID number (1 –12) will
be displayed.
When a standard tone is detected (e.g. 270 Hz, 1 KHz, 2 KHz), a
buzzer will sound and the corresponding modulation frequency will be
displayed. This is useful for fiber identification and signalling. The
meter can also be used to check the actual modulation frequency of
test sources.
If the meter detects a test tone higher than 200 Hz, the display will
show the actual measured modulation frequency in kHz. Maximum
displayed frequency is 2500 Hz.

OPERATION: Power Meter
SlowMode
Slow mode is used to measure power on unstable signals, or signals
that accidentally trigger tone detection. In this mode, Autotest and tone
detection are disabled, and measurement integration time is extended.
In SlowMode, the display will show average optical power of the
modulated signal. The meter response will be slow

OPERATION: Light Source
WARNING! Observe optical safety procedures relevant to the light
source power levels.
To switch on KI 9000 instruments for permanent operation, press and
hold [POWER] during turn-on. ‘Perm’ on the display indicates that the
unit will stay on permanently. Also during instrument turn on:
-to view all display segments, press and hold down []
-to display firmware version, press & hold [HOLD] / [LEVEL]
-for quiet non-beeping operation, press and hold down []
Should the instrument fail to turn on, the microprocessor may need re-
booting. To do this, remove the batteries for at least 40 seconds.
The light source may require a warm up period at the set wavelength
for 15 min to achieve specified stability (ORL< 25dB).
After instrument is turned on, the display shows ‘OFF; the emitters are
off’. To enable a source emitter, press [] or []. Operating
wavelengths will be shown in the top corner on the right hand side and
source power level on the left hand side.
To scroll wavelength, press [] or [].
The mode of operation described below is typically used to perform
continuity testing with the test tone generator.
Modulation is active only while the source is enabled. To select a
modulation tone, press [MOD] to scroll through available settings.
Press and hold [MOD], then press [] to step down or [] to
step up the modulation tone or fiber ID number (1-12).
Press and hold [MOD], then press [] for 3 seconds to set tone
to ID12.
Press and hold [MOD], then press [] for 3 seconds to turn off
modulation.
Laser Output Power Adjustment
This operation mode can be useful so that both 1310 / 1550 nm have
the same power meter reference level, to make dual testing easier.
To decrease the laser output power, turn the laser ‘on’, then press
[LEVEL].
Press and hold [LEVEL], then press [] to step down or []
to step up the output power.
Press and hold [LEVEL], then press [] for 3 seconds to set
output power to factory default. Alternatively, press [POWER].
Press and hold [LEVEL], then press [] for 3 seconds to set
output power to minimum.
Note: This function is not available on the LED source option, and may
be inaccurate on VCSEL laser sources.

KI 9000 UM-10
16
TAMPERLOCK MODE
TAMPERLOCK
TamperLock Mode enables lower skill, repetitive and error-free
measurements, such as fixed wavelength or laser output power.
This is useful to, for example, pre-set an instrument for use by
unskilled personnel, or to just lock the instrument down for easy use
for one specific application.
This achieves the operational simplicity of very basic instruments, yet
allows the instrument to be re-configured as needed, so achieves both
objectives.
To set up this mode, configure the instrument, and enter a unique PIN
code. As long as this is maintained, the instrument is locked into this
mode.
It’s possible for a user to end / escape this mode (maybe they have
changed work sites etc.). To re-apply the mode requires adding
another PIN code.
After a job is complete, entering the known pin code will show a “pass”
if the instrument is still in TamperLock mode, or “fail” if it has been
escaped.
Power Meter
While in TamperLock Mode, user is prevented from changing
wavelength, dB/dBm/mW, Hold, min max and SlowMode settings.
See Power Meter Quick Reference Guide at the end of this manual for
TamperLock operations.
Light Source
While in TamperLock Mode, the user is prevented from changing
wavelength or laser output power.
See Light Source Quick Reference Guide at the end of this manual for
TamperLock operations.

KI 9000 UM-10
17
AUTOTEST MODE
AUTOTEST
This feature is on the Light Source, not the power meter. It can be used
with other Kingfisher power meters such as the KI2000, KI3000.
KI7000 series.
Autotest performs automated loss measurement and wavelength
detection by data exchange between a Light Source and Optical
Power meter. Major labour savings can be achieved.
Autotest detection remains activated for about 8 seconds after fiber
disconnect, so the user can change optical connections without re-
starting Autotest each time, thus achieving productivity gains. Autotest
reduces source warm up drift and battery consumption compared to
manual operation.
Autotest works in situations where high loss or wavelength selective
elements stop some wavelengths from transmitting. The meter will
detect and show whatever wavelengths are successfully received.
Instrument compatibility
Any Kingfisher Autotest source / power meter / loss test set / two-way
tester can be used as a source & meter, for one direction loss testing.
Both instruments must have matching source and meter wavelengths.
Initiating Autotest
Connect an Autotest light source to an Autotest power meter with an
appropriate test lead, and turn on the instruments. On the light source,
press [Auto], the light source will cycle through all available
wavelengths (limited to 5*) and the meter will automatically switch to
Autotest mode and follow it. The meter detects the correct
wavelengths, and displays the nominal source power in dBm of the
respective wavelengths.
See Light Source Quick Reference Guide at the end of this manual for
Autotest operations
