7.1.3 Errors During Measurement
Main error messages displayed during measurement or during measurement of correction
values are as listed below.
Error message Content and Cause Corrective action
Trigger ignored
・
When trigger source is INT
(internal), an attempt to apply
other trigger was made and thus
that trigger was ignored.
Set the trigger source correctly
according to actual trigger signal.
・
Though the device does not wait
for trigger, an attempt to apply
the trigger was made and thus
that trigger was ignored.
Possible causes will be as
follows:
1) During the measurement, the
trigger is not accepted.
2) If *RST command is executed,
continuous initiation is disabled,
and thus the trigger
immediately after that is not
accepted.
For the operation from the panel,
initialize by pressing
_ SHIFT _ +
[INIT], _ 1 _
keys.
For the operation from remote
control,
1) Send :ABORT command to abort
the measurement once.
2) Send :INIT:CONT ON command
or :INIT command to place the
device in trigger waiting status.
・
The device is in over-temperature
statue, and thus the trigger was
ignored.
Allow time until internal
temperature lowers sufficiently, and
reset the error.
Correction meas
failed OPEN, SHORT, LOAD correction
values could not be measured. Perform usual measurement to check
the condition where measurement
failed, and then remove a problem.
Timeout error
・
As the measurement impossible
state lasts for a long time, the
measurement was terminated
forcibly.
Main cause is large external noise
or electrostatic discharge.
Install device or cables that
generate large noise away from the
LCR meter.
Beware of charged device or human
body so as not to discharge to the
LCR meter during measurement.
Over
Temperature
(Tripped)
・
Over-temperature was detected.
The drive signal level becomes
zero, disabling new
measurement.
Main causes will be as follows:
1) The impedance below 1  was
measured for a long time at a
place of high ambient
temperature.
2) Cooling fan is defective.
Remove a cause of
over-temperature, and then allow
time until internal temperature
lowers sufficiently, and reset the
error.
1) Restrain the internal
temperature by lowering the
ambient temperature or
executing intermittent
measurement by triggered drive.
2) Please ask NF Corporation or
one of our representatives for
repair.
Over
Temperature
(Removed)
・
Though over-temperature was
detected, the temperature has
already lowered at which the
device can operate.
Press
ENTR | [EXIT]
key to reset
this message, and the device will be
recovered to usual operation.
Other error message may be displayed according to the situations.
For warning messages displayed due to various operations, see the description of each
operation.
