Chapter 3 Getting Started
3.8.2 Programming the unit for recording
There are a number of parameters that need to be set up before actual recording can take place. These are:
which channels or points to record, at what rate to record them, and how to record them (Fill Mode and Data
Mode). You must also arm the unit to record the actual data.
3.8.2.1 Setting Which Points to Record
To set which points you wish to record:
1. From the Program menu, use the
UP (
↑↑↑↑↑
)
or
DOWN (
↓↓↓↓↓
)
button to highlight
Record Setup
and then press the
ENTER
button. This will bring up the
Record Setup
menu as shown in Figure 3-12.
2. From the
Record Setup
menu, use the
UP (
↑↑↑↑↑
)
or
DOWN (
↓↓↓↓↓
)
button to
highlight
Points
and then press the
ENTER
button.
3. A window pops up and displays
point 1=no
or
point 1=yes
. To record this
point press the
YES
button or to exclude this point press the
NO
button.
You will automatically move to the next point. You can exit this menu at
any time by pressing the
EXIT
button, or accept any entry by pressing
then
ENTER
button.
4. There are fifteen possible points: 1-9 and A-F. For this example, set points
1,2,3 and 4 to
YES
.
5. Once you are done setting which points to record, press the
EXIT
button to
return back to the
Record Setup
menu.
3.8.2.2 Setting the Record Rate
The
Record Rate
is the rate at which data is recorded to disk. It may be set independently for each
channel or for all channels together. It may be set from a fastest time of eight times per second by setting
the record rate to 0 seconds, or the slowest rate of once every 600 seconds (ten minutes).
To set the
Record Rate
:
1. From the
Record Setup
menu use the
UP (
↑↑↑↑↑
)
or
DOWN (
↓↓↓↓↓
)
button to highlight
Record Rate
and then
press the
ENTER
button.
2. Use the
UP (
↑↑↑↑↑
)
or
DOWN (
↓↓↓↓↓
)
button to highlight
All Rates
, ignoring Individual Rate and Autorate for
now, and then press the
ENTER
button. This will set the Record Rate for all channels simultaneously.

menu.
NOTE:
For this example, both the high and low Record Rates are set the same. The Record Rate can be
changed by an external event if the Digital I/O option is fitted or by an alarm event.
3.8.2.3 Setting the Fill Mode
There are basically two record
Fill Modes
:
Fill to End
or
Cycle Data
(Cyclic). The
Fill to End
mode
records data on the disk/card until the disk/card is full and then the recording stops. The Disk Status area
on the Status Bar of the display shows the percentage of disk/card space used. The
Cyclic
mode records
data on the disk/card in blocks and once the disk/card becomes full, the first block of data recorded is
overwritten by the most current block of data. A block contains approximately 500 samples, thus the 500
oldest samples are replaced with 500 newest samples. This continues to happen until the recording is
stopped by the user. The Recorder recycles the space on the disk/card and can record indefinitely. The
oldest data is always replaced with newest data and you will have a record of the most current data. The
amount of data that will be on the disk/card is calculated as described earlier in Section 3.8.
