Startup Error Messages
As part of the self-test performed on startup, a number of error messages can be
displayed indicating operating problems. In addition, the offset and bias values of
the probe are measured each time the probe is zeroed. If an erroneous reading
is detected, the HI-1710A Microwave Measurement System will display the
parameter screen and the erroneous reading will flash. A message will also be
sent to the RS-232 port. Following is the action to be taken for each error.
REF C – OUTSIDE LIMIT
 1.24-volt supply low
 1.24-volt supply high: The 1.24 volt reference to the A/D converter is
beyond specification. Return for service if error message persists.
+5SUP C – OUTSIDE LIMIT
 5-volt supply low
 5-volt supply high: The 5-volt logic supply is beyond specification.
Voltage is not user-adjustable; return for repair.
+8SUP C – OUTSIDE LIMIT
 8-volt supply low
 8-volt supply high: The 8-volt supply to the analog circuitry is beyond
specification. Voltage is not user-adjustable; return for repair.
-8SUP C – OUTSIDE LIMIT
 -8-volt supply low
 -8-volt supply high: The negative 8-volt supply to the analog circuitry is
beyond specification. Voltage is not user-adjustable; return for repair.
