GE VMIVME-3100 analog-to-digital conversion module
allow storage of new data, allowing continual data collection. The last five calibration, validation andalarm reports are retained, independent of time stamp.
The standard report (see Figure 4-5) displays inject time, sample stream, analysis name,
report type, detector, component Name / Retention Time / Concentration and validity of the
component.
Figure 4-5: Standard report format
The raw data report (see Figure 4-6) displays the actual value of software-determined points
on the chromatogram in addition to the information displayed in the standard report format.
The times shown are in seconds from the start of the method. The amplitudes are in 0.1
microvolt units. The Start of Baseline / End of Baseline amplitudes are relative to electrical
zero. The other amplitudes are relative to the computed baseline. Areas are in millivolt-sec
units.

To view the last saved report by stream:
1. Select the analysis from the list on the left.
2. Select the Previous report box.
3. Select the stream.
4. View the report.
5. Select Raw to view in raw data format.
To view a stored report:
1. Ensure the Previous box is cleared and select the Raw box if raw data is preferred.
2. Select the Stream from the first drop-down list.
3. Select the timeframe from the second drop down list. Standard analysis data is saved in hourly
folders in Year/Month/Day and Hour format or alarm reports for the select stream.
4. Select the report inject time to view. Reports are saved by inject time in the following format:
TYPE/Year/Month/Day/Hour/Minute/Second (STD201507301629).
5. View the data (see Figure 4-6).
4.2.4 Overlay subtab
The analyzer supports the overlaying of stored chromatograms on the screen for use as a reference. A
maximum of two stored chromatograms can be viewed simultaneously on the Chart Subtab, plus the
active stream.
IMPORTANT NOTE: If the analysis is not currently running, select Idle Stream to retrieve data
about that analysis.
The Home>Overlay subtab displays the choice of Overlay 1 and/or Overlay 2. Both overlays allow
selection of chromatograms saved on the SBC (see Figure 4-7).
Figure 4-7: Home>Overlay Subtab

Legend: Home>Overlay Subtab
ID Description
1 Active – Check to make the overlay viewable on the chart screen.
Overlay 1 – Green; Overlay 2 - Red
2 Previous – Selects chromatogram from the selected stream’s last completed analysis
3 Lock – Press to lock the selected chromatogram (keeps the chromatogram from being
overwritten).
4 Stream selection – Select stream to display: Calibration, Validation, or Named Stream.
5 Group selection – Select locked, alarm, reprocessed, or by time frame.
6 File Selection – Select file by inject time.
To select a chromatogram to overlay:
1. Press the Home>Overlay subtab.
2. Either press Previous for the last completed analysis, or clear the Previous box to select a
stored chromatogram.
3. Select the year (YYYY), month (MM), day (DD) and hour (HR). Format: YYYYMMDDHR.
4. Select the File from the last drop-down menu. Format: YYYYMMDDHRXXXX where XXXX is the
minute and second the cycle started.
5. Check the Active box.
6. Repeat steps for the second chromatogram, if desired.
7. Return to the Home>Chart subtab to view the overlays.
IMPORTANT NOTE: Overlay 1 (top) displays in green; Overlay 2 (bottom) displays in red.
To turn off the overlay display, clear the Active box on the Overlay Subtab.
The SBC stores analysis data continuously for a maximum of seven days. Report files are overwritten
after seven days or when the storage media is filled.
To manually save a chromatogram:
1. Press the Lock button above the chromatogram file name.
2. Clear the Previous box.
3. From the drop-down menu, select the locked item (see Figure 4-8).
