Section 4 MC-III™ Panel Mount Flow Analyzer
For multipoint calibration, the user selects the Multipoint checkbox, and then enters the number of calibration
points he desires using the “plus” and “minus” buttons on the screen or the page-up and page-down keys on
a computer keyboard. Up to 12 calibration points may be entered. Frequency and factor data-entry fields are
automatically activated for the number of calibration points selected. The user can then enter the appropriate
data for each point.
K-Factor Backup
Each time a calibration factor is entered or changed, the software prompts the user to copy the previous
settings to backup memory (Figure 4.24). In the event that an error is made while entering configuration
parameters, the user can restore the last saved set of configuration settings to the instrument.
Figure 4.24—Prompt to copy previous calibration settings to backup
Select “yes” to save the previous calibration factor to memory. The date and time of this backup is displayed
next to the “Retrieve K-Factor Backup” button on the K-Factor Entry screen. Only the last saved backup can
be retrieved.
To retrieve the last saved K-Factor backup, perform the following steps:
1.
Press the “Retrieve K-Factor Backup” button. A confirmation screen will appear with a prompt to proceed
or terminate the retrieval.
2. Press “yes” to retrieve the last backup.
3. Click “OK” or “Apply” to save the retrieved settings to the configuration file. Because the retrieval of
these settings represents a change to the current K-Factor settings, you will again be prompted to copy the
previous settings to backup.
