Overview

operation is described here.
Typical online data storage tasks
1. Removing, installing, and labeling disks.
2. Initializing new disk using the current Data Storage setup schedules.
3. Checking current storage setup.
4. Starting and stopping storage (3 methods):
a) Start/stop all storage via ENABLE STORAGE menu.
b) Start/stop a particular storage file's storage via its external enable discrete.
c) Start/stop all storage batches via BATCH STATE menu item or via BATCH CONTROL discrete.
5. Checking storage status with DATA STORAGE STATUS display.
6. Replaying data stored on disk.
7. Reading data storage messages.
Installing a disk
The disk must be DOS-formatted. Formatting may be done at a PC or in the instrument with DATA
STORAGE menu item FORMAT DISK (1.44MB disk only). Maintaining a stock of several formatted
disks is recommended to minimize maintenance time on the instrument. For 120MB or Zip disks it is
recommended you preinitialize them using DSU. See Data Storage in section 4.26 for more information.
Disks are inserted and removed from the front panel as described in Table 7-2.
Step
1
Press the button on the underside of the bezel to release the latch. The latch will release easily if you
press the bottom of the bezel back towards the panel to compress its gasket as you press the button.
2
Pull the bottom of the bezel outwards slightly away from the panel and then lift it gently up to fully
open it.
3
Insert the disk into the slot until it catches in place.
4
To remove the disk, press the rectangular button next to the slot. Be sure to label the contents of
each disk.
5
To close the bezel, lower it until it is almost closed. Engage the top edge of the bezel first and then
swing the bottom inward. Press the bottom in firmly until the latch clicks into place. Be careful to fully
close the bezel, or the unit will not function normally.
