Prewarming
The test wells can be prewarmed to 37 °C ±1.0 °C on command. On completion, 3 short beeps are emitted.
Note: Refer to assay package inserts for prewarming requirements.
Automatic Shutdown
When operating from the battery, the system shuts down automatically after 15 minutes of inactivity. This
15-minute interval cannot be changed. When operating from the AC/DC Power Module, the system
automatically shuts down after an interval of inactivity defined by the supervisor.
Note: The factory default setting is 60 minutes.
All stored data is retained after an automatic shutdown.
Test Termination
A test is terminated if clot formation is not detected within 1,500 seconds after starting the test. A FAULT
>1500 message is then displayed and stored in the database, indicating the test result is outside of the
specified range.
Note: Results that are greater than the specified time are beyond the sensitivity range of the test.
They should be repeated immediately and, if confirmed, reported as greater than the maximum time.
A test is automatically terminated if after pressing START a test tube is not inserted into that well within 60
seconds or if a stable magnet is not detected in that well within 75 seconds.
