Very handy: small and lightweight
Extremely simple to operate
Switchable wavelengths
Available reference level measurement mode
Wide dynamic range and high accuracy
All popular fiber cable connectors supported
The display back-light is rather weak
Expert Opinion
1-6.
Do you know the wave-
length of your fibre optic
system? No problem, measure
the same signal for different
lambda and the highest read-
ing indicates the wavelength;
in our case this is evidently
1490
nm because the maxi-
mum reading is just for this
setting
7.
After pressing the REF
button for 2 seconds, the
current level (-0.57 dBm)
becomes the reference level
8.
Now we have switched to
reference measurement mode
by pressing the dB button
9.
Measurement results are
reffered now to -0.57 dBm
10.
If you prefer, you may use
mW rather than dBm units
