ZEISS
Function
When the battery supply unit is connected to a power outlet via the plug-in power unit, the bat-
teries are charged automatically (green power-on light
Ready
is on).
While charging is ongoing and the microscope is connected to the battery supply unit, the micro-
scope can be used without any restriction. It is provided with voltage through the supply line.
The battery supply unit does not need to be switched off. The unit will switch off automatically as
soon as the reflected-light and the transmitted-light illuminators are switched off at the micro-
scope.
Depending on the capacity of the batteries used, the microscope can be operated for about six to
eight hours with battery power.
If the battery charge status has reached its critical value, the battery supply unit will switch off the
power supply to the microscope.
In order to continue working and to charge the batteries, the unit must be connected to the
mains power supply. Shortly before automatic disconnection of the rechargeable battery pack (ex-
haustive discharge protection) the green power-on light
Ready
will begin to flash - at this point,
and no later, the battery pack should be connected to the mains power supply to recharge.
3.2.6 Condenser
Purpose
The condenser focuses the light from the light source to illuminate the object as evenly as possi-
ble, and to guide it as accurately as possible into the imaging beam path.
Position
The condenser is mounted on the condenser carrier behind the specimen stage.
