User manual

MC-III™ EXP Flow Analyzer Section 4

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 elds 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 4.25). In the event that an error is made while entering conguration

parameters, the user can restore the last saved set of conguration settings to the instrument.

Figure 4.25—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 (Figure 4.26, page 68). 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 conrmation 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 conguration le. 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.
