Editing Qc Criteria; Specifying Logged Out Settings - BIO RAD ZE5 User Manual

Chapter 5 Configuring the System

Editing QC Criteria

Administrators can edit the criteria used to determine whether the instrument passes or fails quality
control (QC). Changes to these criteria apply globally to the system.
Caution: Adjusting these values might affect overall system performance. Only
experienced users who can evaluate potential affects on system performance should
edit QC criteria.
An administrator can set two criteria:
n Max Voltage Change — the maximum change in PMT voltage (measured from the baseline for
each channel) required to bring the population to channel 128. The change in voltage required to
place the population in the center of the histogram must be less than this value.
n
Max CV Increase — the maximum increase in the calculated coefficient of variation (CV)
(measured from baseline for each parameter) must be less than this value.
To edit the QC criteria
1. In the Home window, click Global Preferences.
2. In the QC Criteria area, adjust the values for QC Max Voltage Change and QC Max CV Increase.
3. Click OK to save the changes.
