Overload indications when the cell is being connected or disconnected are common and usually do not
indicate a problem. Overloads can also be seen when one of the cell leads is disconnected from the other
cell leads, even though the cell is off. Again, this does not indicate a problem.
A steadily glowing Overload LED during an experiment most likely indicates a problem is occurring.
Possible causes include:
• One of the cell leads is disconnected (this is the most common cause),
• A gas bubble in the cell is blocking one of the electrodes, or
• The potentiostat could be oscillating (see the next chapter).
Rear Panel
The rear panel contains one switch and a large number of
connectors.
Power In Jack
The Reference 600+ derives all its power from +24 V
DC input through the Power In jack. The input current is
less than 3 A.
Always use the external power supply supplied with your
Reference 600+ to supply DC power to the instrument.
This supply is rated for operation from 100 to 240 V AC,
at frequencies from 47 to 63 Hz. It should therefore be
useable worldwide. While a Reference 600+ may work
with other power sources, we cannot guarantee it will
work to its full specifications.
If you have to use the Reference 600+ with a different
supply, make sure that the supply is regulated, has an
output between 22 and 26 V, and supplies 3 A of load
current.
Power Switch
The Power switch is just below the Power In jack. It
A glowing red Overload LED does not necessarily indicate a system malfunction. The
Overload LED can illuminate when one or more cell leads are disconnected, without indicating a
problem with the system. The Overload LED can often illuminate momentarily during a swept or
stepped experiment. The only Overload LED indication that definitely points towards a problem is a
continuously glowing Overload LED during an experiment.
