Instrument Shutdown

To shutdown the HEMOCHRON Jr. Signature+, press 0 (zero) to display the main menu and then press 4.

Or, press and hold down the START key for four seconds. If not in use, the instrument will automatically

shutdown after five minutes.

Test Cuvettes

Tests are performed with single-use disposable HEMOCHRON Jr. test cuvettes. Each test cuvette contains a

label, a sample well, a test channel containing reagents, an enclosed waste reservoir, and optical

detection windows.

The cuvette label is human- and instrument-readable. The current test is automatically read by the

instrument and displayed for confirmation when the operator inserts the cuvette into the test chamber.

After the cuvette has warmed to 37 ±1.0 °C, ADD SAMPLE and PRESS START are displayed by the

instrument, alerting the operator to place a drop of blood in the sample well and begin the test by pressing

the START key.

Note: Refer to the package insert accompanying the HEMOCHRON Jr. test cuvettes for storage

and handling instructions.
