GENERAL
1.1 Description
The
PROLITE
series has been specifically designed for the *operation (start-up) and
maintenance of optical fibre installations. This series consists of two light sources, the
PROLITE-80 and the PROLITE-81 , and two optical power meters, the PROLITE-20 and
the
PROLITE-21
.
The PROLITE-20 and the PROLITE-21 are two portable, sturdy, low-weight optical
power meters, tailor-made for hand-held work. These features make them ideal tools for
field work.
The basic difference between the
PROLITE-20
and the
PROLITE-21
is their
measuring range. Whereas the PROLITE-20 measures power between - 50 dBm and
+ 25 dBm, for the different wavelengths available, the PROLITE-21 can measure power
between - 70 dBm and + 5 dBm
In both models, when the battery is flat, the low battery (LB) indicator on the screen
flashes and, approximately every 2 s, whether it is activated or not, the speaker also
emits a whistle.
