Operator ID Options
1.
Not Require Operator ID, Valid Operator ID and Valid PIN: Select if entry of an
Operator ID (OID) or PIN is not required when running a test.
2.
Require Operator ID: Select to require entry of an OID when running a test.
3.
Require Valid Operator ID from Operator Table: Select to allow operation of the instrument
only after an authorized OID is entered.
4.
Require Valid PIN Number from Operator Table: Select to allow operation of the instrument
only after an authorized Operator PIN is entered. All PIN numbers must have a corresponding
Operator ID in the Operator Table.
Note: Only one of the alternatives listed in steps 1 through 4 can be selected. Authorized
OIDs and/or PINs are entered in the Operator Table. Both OID and PIN should be unique for
each authorized operator or group in the Operator Table (see page 36).
5.
Reuse Operator ID: Enter a value (from 1 to 240 hours) to allow the instrument to use the
OID from the previous test as the default entry for the current test.
Note: The OID will be entered by default for the specified length of time. The default OID can
be changed if needed. If 0 is entered, the OID will not be reused.
Patient ID Options

Require Patient ID: Click Yes to require entry of a PID when running a patient test.
2.
Patient ID Length: Select the number of digits (from 3 to 9, or 0 for any number of digits

3.
Reuse Patient ID: Enter a value (from 1 to 240 hours) to allow the instrument to use the PID
from the previous test as the default entry for the current test.

Specifying QC Lockout Parameters
QC lockout parameters specify the maximum length of time that can elapse before liquid quality control
(LQC) or electronic quality control (EQC) must be successfully run. When the lockout interval has elapsed
and the test cuvette is inserted into the instrument, the user will be prompted to perform the appropriate QC.
If 911 Limits are enabled, the user will be offered the choice to run a patient test. If this option is selected,
the instrument displays the number (from 0 to 240) of remaining tests that can be run (the 911 override)
before QC must be performed (see To Specify QC Exceptions on page 35). Separate requirements can be
specified for the frequency at which EQC and LQC for various tests must be run at normal and abnormal
levels.
