SAFETY CONCERNS
TURN OUTPUT OFF BEFORE ACCESSING DUT
Always turn the output off before opening the rear-panel DUT door, using the front
panel menu or by computer command (“output off”).
If you do not disable the output first, the output will be automatically disabled by a
sensor on the DUT door when it is opened. However, the user should not rely on this
for safety purposes.
Always check that the front panel indicates that the output is “off” before touching the
DUT area.
For maximum safety, turn off the instrument before accessing the DUT area.
AUTOMATIC TIMEOUT
The output is disabled automatically after 90 seconds of inactivity (i.e., unchanged
pulse settings). The timer resets each time a pulse parameter (amplitude, rise time, etc)
is changed.
OVERLOAD INDICATOR
The front-panel “overload” indicator should always glow green, and never amber
(except briefly when the instrument is first turned on).
If the overload indicator becomes active (amber), stop using the instrument
immediately.
