5. Setup

5.1 Unpacking and Placement

  1. Carefully unpack the KT-8000 analyzer and all accessories from its packaging.
  2. Place the instrument on a sturdy, level workbench in a well-ventilated area, away from direct sunlight and heat sources.
  3. Ensure there is adequate space around the instrument for ventilation, maintenance, and access to ports.
  4. Verify that the power supply matches the instrument's requirements (AC 100-240V, 50/60Hz).

5.2 Connecting Power and Peripherals

  1. Connect the power cord to the instrument and a grounded electrical outlet.
  2. If connecting to a Laboratory Information System (LIS), use the network port and ensure proper HL7 protocol configuration.
  3. Connect any desired USB peripherals, such as an external printer or barcode scanner (if not built-in), to the available USB ports.

5.3 Reagent Installation

  1. Refer to the reagent compartment diagram (if available in the full manual) for correct placement of diluent, lyse, and other necessary reagents.
  2. Ensure all reagent lines are securely connected and free from air bubbles.
