IM MX100-01E
Status detection: There are two types of statuses.
CF card inserted: Yes/No, CF card usable: Yes/No
• When the CF card is not inserted:
Inserted: No, Use: No
• When the CF card is inserted:
Inserted: Yes, Use: Yes
• When an error occurrs*:
Inserted: Yes, Use: No
• After pressing the access stop switch **:
Inserted: Yes, Use: No
* If a media-related error occurs and the card can no longer be used,
further data storage is stopped. To clear this condition, press the
access stop switch (see section 2.8) and eject the CF card. Check
the contents of the CF card and log file on the PC, and insert the
CF card again.
** If you press the access stop switch and the card can no longer be
used, further data storage (excluding the creation of a log file) is
stopped. The status is automatically cleared the next time recording
is started.
Timeout time: Initial value 60 s (settings can be changed using the MXLOGGER
or MX100/DARWIN API (sold separately)).
To save the data so that no dropouts occur, the timeout time*
must be set appropriately.If the setting is inappropriate, an error
is indicated on the 7-segment LED, and data storage is not
performed. For details on the display on the 7-segment LED, see
“Media-Related Errors” in section 3.1.
* Timeout time setting (guideline)
Timeout time [s] < 2 [MB]/(data size per second) - 20 [s]
Data size per second is the total for all measurement intervals.
Data size per second for each measurement interval = Time 16
[bytes] + (measured value 4 [bytes] × the number of channels)/
measurement interval [s]
Example.
Measurement interval: 10 ms (1 type), no. of channels: 60
Data size = (16 bytes + (4 bytes × 60))/0.01 [s]) = 25600 [bytes]
Thus, the timeout time is
(2[MB]/25600[bytes])-20[s]=61.9[s]>
60[s]
Saved channels: Measurement channels monitored on the PC
(not recording channels)
Save interval: 60 s (automatically saves using the timeout time as the save interval)
Filesize: Approx.5MB/le(foralewithminimummeasurementinterval)
Data size per channel: 4 bytes
File name: MDDIXXXX.MXD
M: Month when saving started (local time), 1-9, X (October),
Y (November), Z (December)
DD: Data when saving started (local time), 1-31
I: Measurement interval number, 0-2, up to three types in
order from the shortest measurement interval (if the
measurement (monitoring) interval is the same even when
the measurement group is different, the data is saved to a
singleleofthesamemeasurementintervalnumber.))
XXXX: Sequence number 0000-9999
MXD: Extension(upper-casecharacters)specictotheMX100
Guarantee of data during power failure:
Writing of data up to immediately before the power failure is
guaranteed (saving (backup) is not continued after the power
failure recovers.)
