To
stop the unit from recording
:
1. Follow steps 1 through 3 from Section 3.8.3.
2. Use the
UP (

recording.
4. Wait for the disk light to go out and the
Disk Status
area to say
OFF x%
before removing the disk/card.
5. Press the
EXIT
button three times to return to the default display.
3.9 Hot-Swap
Hot-Swap
is the ability to “Swap” disks/cards without turning off the record status so
there is no data loss. As soon as a disk/card is removed a window will appear (see
Figure 3-13) displaying the amount of time left before data is lost. For the fastest
Record Rate of 8 times per second, you will have approximately 2.5 minutes (see chart
below figure). Each pen has its own buffer so the approximate times listed are for any
number of pens. The time in the window will count down in two second intervals for
sample rates faster than 2 samples per second. The window will count down in
intervals equivalent to the sample rate for rates faster than 2 samples per second. If
there are different Record Rates, the buffer time displayed will be for the fastest
Record Rate.
WARNING:
Do not remove the disk/card while the green light is on.
To
Hot-Swap
:
1. Wait until the green light is not on and take the disk/card out of the drive.
2. When the disk/card is pulled out, the
Disk Status
area will indicate
NO MEDIA
and the
Media Missing Buffer Time
window will appear displaying the time left
before data is lost.
3. Insert a new
formatted
disk/card into the drive, and the unit will continue recording.
WARNING:
If the disk/card is not replaced within the time frame displayed,
data will be lost
.
3.10 Changing File Names
The user can name files to help identify the process being measured. The system uses a single filename for all
types of files, pens, alarm, and configuration. The filename can be any DOS compatible name. Filenames can be
changed as often as needed and multiple file sets can be recorded onto the same disk/card. Multiple configuration
files may also reside on a single disk/card.
To change the
Filename
:
1. From the
Record Setup
menu use the
UP (
↑↑↑↑↑
)
or
DOWN (
↓↓↓↓↓
)
button to highlight
Filename
and press the
ENTER
button.
2. An alphanumeric keypad will appear and the current filename will be displayed. Use the alphanumeric keypad
to enter up to eight characters for the new filename. Do not enter any file extension or “.”.
3. Once you have entered the filename you want, press the
ENTER
button.
