Setting up Correlation Coefficients
Use this procedure to enter slope and offset (intercept) values to correlate the patient
sample results from the Rapidlab
1200 system to those obtained using another
measurement system. The following table lists the valid ranges for slope and offset:
1. Select Status > Setup > Secured Options.
2. Select the down arrow button and then select
Correlation Coefficients.
3. Enter the slope and offset values for each parameter that you want to correlate to
another measurement system.
4. Select
Save.
Setting up Maintenance Functions
The following functions are available on the Secured Options > Maintenance screens:
• Setup Schedule
• Export Schedule
• Import Schedule
Setting up a Maintenance Schedule
At the Maintenance–Schedule screen, you can perform the following tasks:
• view maintenance task details
• add up to ten user-defined maintenance tasks
• edit predefined and user-defined maintenance tasks
• delete user-defined maintenance tasks
• enable or disable some predefined and user-defined maintenance tasks
CAUTION: Do not change the correlation coefficients until you collect the
appropriate data. Changing correlation coefficients affects the reported results for
patient samples. Before changing correlation coefficients, determine the slope and
offset values, as described in Performing a Correlation Study‚ page 2-34.
