file) during the background collect time. The (s) column can be used to check
whether the background collect time is as expected (default is 5.0 s), based on the
time set in the F2 – Wait Timeouts screen.
Additional columns shown in the data log raw_bkg.csv file are Carrier board
readings “+5V”, “+12V”, “-12V”, “°C”; “kg” and for each detector “HV” (high
voltage setting). The “kg” is used to trend the weight setting to check for drifting
values from load cells holding the Scale Tray.
Calibration Trend Log
New data is appended to the Calibration Trend Data log (filename
CALTREND[*][*].CSV) when leaving the Calibration screen providing that a
Calibration or Calibration Check collection was done on at least one detector while in
this screen. If both were done then each gets its own entry row in the file. Changing
the efficiency to Factory Default or Manual Calibration is also considered as a
Calibration collection for this purpose.
The column headings and associated data format are:
Type: “Calibration” or “Check”
Note that if Type is “Calibration” then Efficiency shown is current efficiency, which
could be Calibrated, Factory Default, Manual Calibration or in case of sum zones,
Derived. Also note that if type is “Check” the zones without a “check” efficiency are
left blank.
Column 5 to Channel 1 end: Channel 1 Efficiency for each Channel 1 Zone
Column Channel 2 start to Channel 2 end: Channel 2 Efficiency for each Channel 2
Zone.
Verification Test Trend Log
The Verification Test Trend Data log (filename VT_TREND[*][*].CSV) is used to
trend Verification Test data.
It is only available when Alarm Test Settings, Alarm Test Type is set to
“Verification Test”.
The column headings and associated data format are:
Column 4: Corresponding Verification Test Results file name.
Column 5 to N – Column for each zone containing Net Rate measured during
Verification Test.
1st row: column labels
2nd row: expected rate (labeled such in column 4 instead of file name)
3rd row to N: one row for each verification test
