batteries are fully charged, as the turned on/activated operator terminal draws power from
the batteries. This however has no influence on the safety or on the battery lifespan.
A full charge cycle takes approximately 3 to 4 hours. A partial loading or unloading is
permitted and has no negative impact on the battery lifespan or its capacity. As soon as the
battery charge indicator in the display lights up red, the batteries should be recharged.
5.5 Handling the Brass Cups
A brass cup is assigned to each output channel. The output signal is fed via the brass cup
and then to the left banana socket and the BNC socket.
The brass cups can be removed, if necessary (e.g. for cleaning purposes). To enable this,
one must remove the large cup tray cover and the covers of the brass cups. Afterwards each
brass cup can be pulled out with little effort.
All three brass cups are identical, so they can be safely exchanged between the channels.
For reconnecting the brass cups, make sure that they are fully inserted. They must be put
in with some force, to close the contact. The contact is made only on the last 5 millimetres
of the downward movement.
