Cleaning / Disinfection Of The Flow System; Sensor Replacement - EKF Diagnostics Biosen C-Line Clinic User Manual

6.2 Cleaning / Disinfection of the flow system

The chip sensor is destroyed by the used solutions. However, a
chip sensor has to be in the measuring channel. Only carry out this
procedure if the sensor needs to be changed or an old sensor or
dummy sensor is available.
The solutions to use must be obtained from EKF-diagnostic GmbH (see section
10.1) and be prepared according to the enclosed operating instructions. Afterwards
place the micro test tube in position C1, start the procedure under main menu/
maintenance/cleaning and follow the instructions on the display.

6.3 Sensor replacement

Chips sensors are subject to deterioration and must be replaced at regular
intervals. Dummy sensors can be used as long as there are no leaks in the
flow system.
It is possible to check the chip sensors with a sensor test solution or a linearity
solution (see section 10.1).
Ensure that the right sample type is chosen before you start a
measurement. The sample type must be set as Plasma for
measurement of sensor test solution or linearity solution.
Only Replace sensors when the device is connected to the mains supply.
Open the sensor holder as described in section 4.2.3 and remove the old sensor.
The display will read "Please insert sensor!".
Do not touch the electrical contacts and do not apply moisture to
the electrical contacts. Carefully dab away moisture on the flow cell
and sensor bracket using a lint-free cloth.
