Remedy and Reference
Open correction or
short correction re-
sulted in an error.
The instrument is being used in
an environment characterized
by a large amount of noise.
If you are using the instrument in a high-noise
environment, consider taking the following mea
-
sures:
•Use guarding.
See"Appx. 2 Measurement of High Impedance
•
Implement anti-external noise measures.
See"Appx. 4 Countermeasures Against Incor
poration of External Noise" (p. Appx.5).
•
Separate the sample, measurement cables,
and instrument from the source of the noise
(motor, inverter, electromagnetic switch, power
line, equipment generating sparks, etc.) or
perform the measurement in a separate room.
•Plug the instrument into a grounded outlet.
•
Use a separate power supply from the device
that is generating the noise.
An error beep sound is
emitted continuously.
The measured value automatic
output function has been en
-
abled.
When the measurement value automatic output
function is enabled, perform the receive opera
-
tion on the computer side. Failure to do so will
result in a transmission error on the measuring
instrument, and the transmission error tone will
continue to sound in the event of an internal
trigger, etc.Perform the receive operation on the
computer side and then perform measurement
on the measuring instrument side, or disable the
measurement value automatic output function.
Refer to the Communications Instruction Manual
on the bundled LCR Application Disc.
Communications
You are unable to
send and receive data
using RS-232C.
A straight cable is being used.
Use a cross cable.
The wrong COM port is being
used.
Check whether the computer's settings match
the connected COM port. Connect the cable to
the proper COM port.
Check the computer's settings. The COM port
may be selected at the operating system, driver,
or application level. Check all of these settings.
The computer has no COM port.
Consider using a commercially available USB/
RS-232C conversion cable.
The instrument is unable to
communicate with the applica-
tion.
Check whether the instrument is turned on.
Turn on the instrument and complete any inter-
face connections before launching the computer
application.
For more information about external control, see "9.5 External control Q&A" (p. 185).
