•
The meter or source was much colder when you set the
reference.
•
You did not allow enough time for the source to warm
up before you set the reference.
•
You measured loss on a fiber that is shorter than the test
reference cord you used to set the reference.
If loss is negative, set the reference again then measure loss
again.

How to Identify Cables or Fibers

You can use the 2 kHz modulated signal from the source to
identify cables or fibers at patch panels. The meter shows
2 kHz on the display when it detects the modulated signal.
To use the 2 kHz mode to identify cables or fibers
1 On the source, hold down

Press to put the cursor next to MODE, then press

to set it to ON.
2 On the meter, press
measurement mode. You can also select loss
measurement mode, but the display is easier to read in
power measurement mode. If necessary, press
set the meter to the same wavelength as the source.
The source's auto wavelength function does not
operate when you use 2 kHz mode.
To identify cables, use an MTP/MPO cable to connect the
meter to cable outlets. To identify fibers, use a breakout
cable to connect the meter to single or duplex fiber
outlets.
3 When the meter receives the 2 kHz signal from the
source, 2 kHz shows on the meter.
If you use a breakout cable to connect the meter to an
outlet, the channel indicator on the meter moves to the
channel that is connected to the source. You can also
turn off the SCAN ALL function on the source, then
change the channel on the source to identify
connections.
