3.3 Setting the Measurement Conditions

• If the measurement values displayed on the unit are outside of the guaran-
teed accuracy range, the HOLD LED flashes.
• For errors other than measurement value outside of range errors, refer to
"MAIN display area ERROR display" (p. 14).
• When the measurement is out of the range or the display range, an error
message will be displayed on the MAIN display following the flow chart below.
• A negative measurement value may be displayed.
Factors which may cause this include the following:
•
Measuring inductance that is in the opposite phase.
•
The OPEN compensation value is not accurately taken.
•
LOAD compensation enabled.
•
Offset compensation is enabled.
The lowest display value in both the MAIN and SUB displays is "-199999". If
the measurement value is lower than this, "-199999" will be shown in the
MAIN display and "d-UF" will be shown in the SUB display.
• In Range 7 and 8, do not connect low impedance elements (1

or less)
such as static capacities higher than the certified guaranteed range for long
periods of time. It may result in damage on the main unit.
When a low impedance element is connected for more than 10 minutes, an
“i-ovEr Error” will flash on the MAIN display, which will automatically enable
the trigger simultaneous function and terminate the measurement.
To clear the error, open the measurement terminals and then press
.
However, there may be cases when an error message is not displayed
depending on the connected state between the measurement terminals.
For this reason, in Range 7 and 8, do not connect low impedance elements
for 10 min. or more.
• An under flow or CV-Lo (applied voltage abnormality) may be obtained,
depending on the balance condition of the internal circuit when the mea-
surement terminal is opened.
• When the signal level is 100 mV (only for 3504-60), ranges 1 and 2 are
beyond the certified guaranteed range regardless of the measurement fre-
quency.
