File Browsing; Searching Data By Value - Omega RD8800 User Manual

Chapter 3 Getting Started

3.13.1 File Browsing

File browsing can be done at any time, even when still recording. However, if you are browsing from disk/card
while recording, there may be delays in retrieving data from the disk/card as writing to the disk/card has priority
over reading from the disk/card.
To Browse a File:
From the Browse Source Button Bar (Figure 3-14), press the FILE button. The unit will check the disk/card
and then bring up the File Directory window (see below) allowing the user to choose which file to browse.
File Directory
Point 1:
→ BATCH1
.DT1← (Date) (Time) (Size)
BATCH2 .DT1
BATCH3 .DT1
NOTE: Ensure that a disk/card is present and that it has suitable files or you will get an error message.
Use the UP (↓ ↓ ↓ ↓ ↓ ) or DOWN (↑ ↑ ↑ ↑ ↑ ) button to move the arrows to the file you want to browse and then press the
ENTER button. You will enter Browse Mode and the Browse Mode Button Bar will appear as shown in Figure
3-15 below.
The FINDV button allows the user to FIND by Value, while the FINDT button allows the user to FIND by Time.
The BROWS button enters the Interactive Browse feature (see Section 3.13.4). The "
are to used to COMPRESS and EXPAND data respectively, and the EXIT button returns you back to the
File Directory window.

3.13.2 Searching Data By Value

To Search the historic data by Value:
From the Browse Mode Button Bar, press the FINDV (FIND Value) button. This will bring up the Search Value
Button Bar as shown in Figure 3-16 below.
To set up the actual Value to search for, press the VALUE button. Use the numeric keypad to enter the Value
to search for. You cannot search for an exact match; you will be looking for a Value immediately greater than
or less than the Value you enter. Once you have entered the Value you want, press the ENTER button.
Before searching for the Value you set, you have to decide which PEN or point to use as the search reference
and in which direction to search.
Use the PEN button to select the pen trace to search. Each time this button is pressed, the next pen is
selected. The current pen is shown in the Status Line at the top of the screen, together with the value of the
trace under the cursor and its actual time and date stamp.

The File Directory will list the file(s) for each Point,
starting with Point 1. The filenames are specified
by the user at the time of recording and have an
extension of DTx where x is the Point number. The
filename list will scroll if it is longer than what will fit
on the screen. If no files are available for a particular
point, the directory will indicate "No Files Found".
