ATTENTION LABEL
An attention label on the rear of the HEMOCHRON Jr. Signature+ instrument alerts users to accompanying
documentation:
Before using the HEMOCHRON Jr. Signature+ instrument, it is essential that the contents of this
Operator’s Manual are read and understood by the operator.
Handle and open the container with care.
Instrument Lockouts
The instrument can be configured to allow use only by authorized operators and/or to allow use only if
specified QC has been performed. If one or more of these lockouts is enabled, processing of the lockout(s)
occurs before any other instrument functions.
Prewarming
If the lockout checks are passed, a cuvette is automatically prewarmed to 37 °C ±1.0 °C when it is placed in
the test chamber. The instrument will sound one short beep when pre-warming is complete.
Automatic Interrupt
To ensure accurate test results, incubation of a cuvette stops automatically if START is not pressed within
five minutes after ADD SAMPLE and PRESS START are displayed.
Test Termination
A test terminates and operation of the test chamber automatically shuts off if clot formation is not detected
within a test-specific, preset maximum time.
Note: Results that are greater than the time noted in the package insert for a test are beyond
the sensitivity range of the test. They should be repeated immediately and, if confirmed,
reported as greater than the maximum sensitivity range.
