10.10.4.3 Indication of
the battery
status on
the screen and
with PW led
The charge status of the battery is displayed at the right and on the middle
of the PM9010 screen when initializing the PMM 9030.
The symbol of a small battery will be filled up proportionally to the status of
the battery charge.
When the battery is not under charge, the actual voltage value is displayed
under the symbol and the length of the black bar filling the symbol indicates
the available autonomy still remaining.
When the battery charger is connected to the PMM 9030 the indication
"PWR" appears just below to the battery icon and the front panel PW led
becomes yellow if the receiver is switched on and red if the receiver is off.
The battery charging is suspended or ends automatically when one of the
following events occurs:
-
the full capacity of the battery has been achieved,
-
the internal temperature of the battery is higher then a preset safety
threshold,
-
the charging time limit has been exceeded.
Both during recharging and when charge is completed PMM 9030 is ready
for use.
The PW led on the back panel blinks green when the battery voltage
drops below 7,0V to warn the Operator that the instrument is running
out of battery.
To prevent any damage to the battery, the PMM 9030 automatically
switches off when the battery voltage falls below 6,5V.
In order to keep the batteries fully functional, it is crucial to have a
complete recharge before storing them for periods longer than 4
months. Therefore, it is suggested to recharge the batteries at least
every 4 months even when the receiver has not been used.
The PMM 9010 and the PMM 9030 have the same model of battery.
It means they are perfectly exchangeable among the two equipment.
To make an easy example, the 9010 could be installed in an
instrument/control room and connected to the mains, to keep the
battery at its highest charge. The PMM 9030 could be in the test
chamber – connected to 9010 via fiber optic link - and running on its
battery. When the battery of the 9030 is almost fully discharged, the
User can stop the test, replace the battery of the 9030 with a charged
battery (e.g. the one of 9010) and then restart the test.
