4.8 SafeMode
As a safety precaution, the 4176 is designed with an optional Safe Mode feature. With
the Safe Mode option activated, if an overload persists for more then 10 seconds, the
4176 shuts down its current source, and displays “SAFEMODE” on its screen. The
ohmmeter does not automatically recover from safe mode; the user must press the Enter
key or any range (including Auto) to return to measurement mode. This is so that the
user can be aware that an overload has occurred, so that the cause maybe investigated if
necessary.
