OPTICAL POWER METERS
PROLITE-20 and PROLITE-21
1GENERAL
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.

3INSTALLATION
3.1 Power supply
The PROLITE-20/21 is a portable instrument powered by a 7.2 V, 950 mA/h, NiCd,
rechargeable battery. The device is accompanied by an external DC adapter which
enables the PROLITE-20/21 to be connected to the mains for operation and battery
charging.
3.1.1 Operation using the external DC adapter
The instrument comes with a 230 V / 50-60 Hz mains adapter, for EUROPE and other
countries, for powering the PROLITE-20/21. (See accessories for ordering other types of
adapters.)
Once the battery is installed in the instrument, connect the external DC adapter to the
PROLITE-20/21 using the external power connector [8] located on the left side. Connect
the DC adapter to the mains, thereby starting the battery charging process. Next, press
the start/stop button [4] on the PROLITE-20/21. Under these conditions, the instrument
starts to function. Battery-charging time increases if the instrument is used during the
process.
WARNING
Before connecting the mains adapter, make sure that it is the appropriate one for
your mains system.
The mains adapter is designed for indoor use.
Never start the instrument with the external adapter connected if the battery is not
in place.
3.1.2 Operation using the battery
For the instrument to work using the battery, you need only press the start/stop button
[4]. With the battery fully charged and the display not illuminated, the PROLITE-20/21
has an approximate autonomy of 30 hours uninterrupted operation.
When the battery is flat, you will see the low battery indicator on the screen and,
afterwards, the instrument will automatically switch off.

INSTRUCTION MANUAL. PROLITE-20/21
Page 8 February 2001
3.1.3 Battery charging
To fully charge the battery with the PROLITE-20/21 switched off, connect the external
DC adapter to the power supply input [8]. Then connect the adapter to the mains.
Charging time depends on the state of the battery. If the battery is very flat, charging will
take some 14 hours.
3.2 Battery installation
Only use CB-038 batteries.
To install the battery, place it on the base of the arrows at the rear of the instrument.
Slide it in until you hear a “click” and the battery is secured, as shown in figure 1.
