The inductancej
capacitance, or
impedance of the
DUT is too high
to be measured on
the selected LC|Z:
RANGE.
Select a higher
LClzl RANGE.
Overflow - The dissipation
factor, quality
factor, ESR, or
conductance of the
DUT is too high.
Change the DISPLAY
B function, or
change the DISPLAY
A function to
|z|.
Underflow -The
inductance,
capacitance, or
impedance of the
DUT is too low to
be measured on the
selected LC|z|
RANGE.
Select a lower
LClzl RANGE.
Underflow
(any reading)
•The dissipation
factor, quality
factor, ESR, or
conductance of the
DUT is too low.
Change the DISPLAY
B function, or
change the DISPLAY
A function to 1ZI.
Change Function
-The selected
parameter cannot
be measured with
the present control
settings.
Change the DISPLAY
A function to
another parameter.
(any reading)
Change the DISPLAY
B function, or
change the DISPLAY
A function to IZ1.
Zero Offset Adjustment error.
The residuals of the test
fixture or test leads are too
high to be offset, or nothing
is connected to the UNKNOWN
terminals.
Previous Zero
Offset data are unchanged.
Use
a
different
test fixture or
test leads; or, if
nothing is
connected to the
UNKNOWN terminals,
connect an appro¬
priate test
fixture or test
leads.
Refer to
paragraph 3-50
for details on
Zero Offset
Adjustments.
