1. Summary
KI6501 is an easy and economical handheld CWDM Power Meter for
testing multi-λ single mode fiber optic systems. It scans and stores the
absolute or relative power levels of all 18 CWDM λ in 0.8 seconds. Test
data can be viewed in graphical or numerical form, and reference values
can be stored for easy loss testing. The instrument has good ergonomics
which features a large, sunlight readable and backlit colour display, and a
well laid out and easy to use front panel. Data Management Software
enables stored test data to be downloaded to PC.
Applications of KI6501 CWDM Power Meter include the following:
•Wavelength selective Power Meter for systems with CWDM
channel spacing.
•Quickly determine active channels.
•Diverse FTTx systems, RFoG etc.

4. Safety
Take appropriate eye-safe precautions when
handling live fibre.
Avoid condensation
The instrument is resistant to normal dust and moisture, however it is not
waterproof. If moisture gets into the instrument, remove the batteries and
dry it out carefully for at least one hour before using it again.
Storage
The equipment can be stored at the specified temperatures and relative
humidity. Protect the unit from temperature extremes that may cause
condensation within it.
Make sure to switch off the instrument whenever it is not in use. Keep the
optical connector covered with the dustcover at all time.

6.3 PM (Power Meter) Mode
Power Meter can be operated either in PM Auto Mode or PM Manual
Mode. PM Manual mode displays real time power measurement values.
PM Auto Mode:
In this operation mode, the instrument automatically scans the optical
input and displays the wavelength (along with its corresponding measured
power value) which has been detected with the highest level of power.
The instrument is defaulted to PM Auto Mode upon power-ON; otherwise it
can be switched from other operation modes to this by pressing [PM], see
picture below for instruments user interface.
