When a test cuvette (eg. PT) is inserted to turn on the instrument, the following prompts are displayed:
1) HEMOCHRON Sig+ 3) Priming Pump
2 ) Test . . . . . . . . . . . PT 4) WARMING…….... (scrolls right)
Note: The test name for the inserted cuvette is displayed after Test........ . Check the display
for fault messages while the cuvette is warming. Refer to the Troubleshooting section for the
procedure to resolve a fault message.
When the cuvette reaches 37 °C ±1.0 °C, the instrument will beep and alternately display:
Add Sample . . . . . . . and . . . . . . . Press Start
The sample can now be added. After the sample is added, press START to run the test.
RUNNING A TEST
Samples are designated as patient samples by default. If a control is being run, the sample type must be
changed from patient sample to QC Normal or QC Abnormal. If a patient sample is being run, this step
is unnecessary.
Important: Failure to select QC Normal or QC Abnormal for a control sample will result in
storage of the control results as patient results in the patient database.
1.
Select QC to display the QC SELECTS menu:
QC SELECTS
Note: To enter QC SELECTS, a cuvette must be inserted into the instrument.
2.
Press 1 to designate the sample as a normal control:
QC Normal
Or press 2 to designate the sample as an abnormal control:
QC Abnormal
Note: Once the QC SELECTS menu is displayed, the sample type can be selected by pressing
QC repeatedly until the desired sample type is displayed or by pressing the numeric key
corresponding to the desired sample type. The sample type can be designated either before,
during, or after the test is run, while the test cuvette is still inserted in the instrument (unless
QC lockout features are enabled). Once QC is selected, repressing the QC key will briefly
display the QC level and assay being run.
To exit the QC menu, press and hold the CANCEL Key for three seconds.
Important: Once a QC type is selected, it cannot be changed.
Note: If any error messages appear on the instrument screen, do not change any previous
patient/QC tags. Remove cuvette and repeat test using a new cuvette.
A numeric Patient ID (PID) and/or Operator ID (OID) can be entered for each test. The IDs will be stored
with the results for the test. Entry of a PID and/or OID is optional unless specified otherwise (see the
Configuration Manager section on page 26). When entering an optional PID or OID, any ID (up to nine
characters) other than 0 (zero) can be entered.
