Description and Corrective Action
• Try loading the setup file again. If it still fails, the SD
memory card may be damaged if the setup file is on
the card or the CW500 may be malfunctioning if the
setup file is in the internal memory. If the CW500 is
malfunctioning, stop using it immediately.
• Check the free space on the SD memory card and in
the internal memory and the number of saved files.
Up to three measured data files and eight other files
can be saved to the internal memory. If there is not
enough free space, delete files or format the SD
memory card, or use another SD memory card that
has been formatted on the CW500. For details, see
"Recorded Data Operation" in section 5.6.
• This appears when "Start" for recording is set to
Constant rec. or Time period rec., and the stop time of
recording is set to a time in the past. Check the time
settings. For details see "Reserving by Specifying the
Date and Time" or "Reserving a Repetitive Recording"
(section 4.2).
• Check the settings on the Recording tab of SET UP.
For details, see section 5.4, "Recording Setup."
• Start recording again. If it still fails, the SD memory
card may be damaged if the recording destination is
the card or the CW500 may be malfunctioning if the
recording destination is the internal memory.
CW500 is malfunctioning, stop using it immediately.
You can only view the settings while recording is in
progress. To change the settings, be sure to stop
recording, and wait for the message "Recording
stopped" to disappear.
• This appears when a current clamp-on probe different
from the previous measurement is connected.
On the Basic tab of SET UP, specify the currently
connected clamp-on probe, or use sensor detection to
automatically detect the current clamp-on probe.
• An appropriate current probe may not be connected
to a channel for the wiring system to be measured.
Only the same type of current probes may be used in
a measurement.
