3.9 Battery / Power
The instrument can be powered by either the supplied rechargeable Lithium
battery or, by the supplied charger alone.
When operating the instrument with Lithium battery installed, as battery
voltage drops below 6.7volt, a symbol will be displayed, and instrument
will beep for a short instant before powering off automatically.
To recharge, plug connector of the supplied charger into the charging-jack of
instrument. Recharging takes 4 - 6 hours. Charging indicator on charger
turns from red to green when instrument is fully charged.
Standard instrument comes with a charger of US-type AC plug. If require,
order suitable AC plug adapter from Optional Accessories section below.
4. Maintenance
•
Keep the sensors’ surfaces clean and free of dust or other
contaminant by cleaning them regularly.
•
Do not use unclean or nonstandard adapters.
•
Change adapter carefully if necessary and keep any spare adapter
in dirt/dust free environment.
•
When the instrument is not in use, keep the optical connectors
covered with dust caps at all the time. Exposing the sensor for a
long period of time will allow dust to be accumulated on surface of
the sensor; this will in turn result in measurement inaccuracy.
•
Always consider leaving test cords connected to the PON meter.
This will prolong the life of the instrument ONT & OLT connectors.
