If power down occurs unexpectedly while recording to MMC/SD
The Stand-alone models have a built-in file protection feature. If power is lost while recording, all data—prior to up
to 255 samples from the power failure—is available. If power is lost for any reason, the data file will be closed and
saved and a new data file will be started when power is restored (Mode LED will flash red @ 1 Hz) if that option is
selected in the Hardware Manager Stand-alone setup.
LED is green but I cannot format a
memory card. The instrument is looking for a file
that has not been closed (possible due
to power failure). Reinsert the correct memory card
and press the control button for
about 1 second (until LED turns
off) and release. The instrument
gives you three chances to find the
correct file, if it does not you must
format whatever card is there to
begin a new recording session.
Mode LED will not change from
error state (orange). This can be caused by switching
memory cards during a power failure
without giving the instrument a
chance to close the data file. Remove the memory card and
unplug the device. Restore power
to the device (LED should turn
green). Press and hold the control
button for about 1 second (until
LED turns off) and release. If LED
is orange, press it again. When
LED turns green reformat your
memory card.
When memory card is inserted
into a reader a “not formatted”
error is seen. Dependent upon the reader being
used. Sometimes the driver for an SD
card reader appears “dead.”
Reboot your PC.
When attempting to read the mem-
ory card using a card reader, the
PC takes an interminably long
time to open the data. Dependent upon the memory card,
card reader, and the PC you are using.
The amount of time it takes to open
the card will vary. Using the Lock feature on an SD
could speed up the process. Be
sure to try that before purchasing
new equipment.
After viewing data files through a
card reader, upon initiating a
recording session, the LED blinks
orange then turns green. The instrument has a unique file sys-
tem. When the data on the memory
card opens in Windows, sometimes
Windows will modify the file system. You must reformat the card. To
prevent further instances of this
error, use the Lock provided on
your SD card. If you have an
MMC you will have to reformat
the card with each subsequent use.
When attempting to read the mem-
ory card using a card reader, the
data file is huge (completely fills
up the memory card) and the
actual waveform data is difficult
to find. The instrument did not have a chance
to properly close the file. If you have not started using the
instrument with a different mem-
ory card, reinsert the card and
press the LED for about 1 second
(until LED turns off) and release.
The LED should be green indicat-
ing the file is closed and can be
read.
If you have already configured and
used the instrument again, the file
can no longer be closed and you
will have to search for it and cut/
paste the data into a new file.
