400 Hz Option
The HP 70206A System Graphics Display is available with a 400 Hz option that allows the
display to operate on a 400 Hz power-line frequency. The 400 Hz option requires an external
in-line 600 VA isolation transformer (included with the option) when the instrument uses a
400 Hz power source.
Warning
Never operate a 400 Hz option instrument on a 400 Hz power line without using
the in-line isolation transformer supplied for this purpose. Failure to follow this
ý
precaution can create a shock hazard which may result in personal injury.
Caution
Remove the in-line isolation transformer when using 50/60 Hz power source
operation. Failure to remove the in-line 400 Hz transformer will destroy the

400 Hz transformer input fuse. When the isolation transformer is removed,
a standard power cord must be used. The in-line transformer must be
reinstalled when using a 400 Hz power source, in order to protect the user
from electric shock hazard.
