For Single Ended Method
See Figure 1 on page 4.
• Insert ST connector end of Launch Jumper into appropriate wavelength port
on Light Source.
• Insert other connector end of Launch Jumper into Adapter Cap on Power
Meter.
• “Zero” the Power Meter by pressing and holding down the “Ref” button until
“HELD” and “0.00 dB” is displayed.
For Substitution Method
See Figure 3 on page 6.
• Insert ST connector end of Launch Jumper into appropriate wavelength port
on Light Source.
• Insert connector of the Second Launch Jumper into Adapter Cap on Power
Meter.
• Connect the two Launch Jumpers with a Splice Bushing.
• “Zero” the Power Meter by pressing and holding down the “Ref” button until
“HELD” and “0.00 dB” is displayed.
NOTE:
It is recommended to repeat this “zero”
procedure at least every 30 minutes.
For 50 and 62.5 µm testing only, an ad-
ditional step is required: Wind the launch
jumper around the mandrel (provided with
the 50 and 62.5 µm kit only), ensuring the
cable follows each groove and is clipped
into both ends of the mandrel where pinch
ports are evident. The mandrel should be
wound within approximately a half meter
of the source connector end. (

Use the gray mandrel for 50 µm.
Use the black mandrel for 62.5 µm.
