Warning LED
The Warning LED glows amber under the
following conditions:
Probe power-on self test failure
Probe tip over-temperature detected
The input voltage on either the A or B input
exceeds the allowable limit
The Warning LED clears when the condition
causing the warning is removed. A notifier
message of a probe warning condition can also
be seen on the oscilloscope.
CAUTION. Do not exceed the input voltage limits of the probe and probe tips. The probe or oscilloscope circuits may be damaged
if the limits are exceeded. Make sure that you understand and work within the limits of the probe and probe tips.
