formed in the process:

2.
Display check (contrast, lighting, etc.)
3.
Check of correct ergometer rotational speed display
4.
Check of the measurement sensor for brake performance
5.
Check of mechanical power loss of the ergometer’s drive system
6.
Electrical safety check
7.
Check of the pressure measuring unit for the blood pressure recorder
8.
Check of the pneumatic system for leaks
9.
Check of the safety symbols and markings on the casing
10.
Writing of a test protocol
These checks and any recalibrating work necessary should only be performed by authorised and
trained personnel with the special tools required for this purpose.
8.2
Cleaning the Device
The surface of the casing can be cleaned with a soft cloth that is dry or moist. Commercially available clean-
ing agents for household appliances can be used. The seat should be cleaned with imitation leather cleaning
material.
It is imperative to make sure that no water penetrates the device.
The keyboard foil should never be cleaned with petrol, nitro cleaner or acetone.
8.3
Cleaning the Blood Pressure Cuff for 250 HK
The blood pressure cuff is made of watertight plastic foil. It can be washed with a cloth and soapy water.
The water temperature should not exceed 30 °C. It is not advisable to immerse the cuff in soapy water and
then to wash it, as this could cause the fleece and Velcro strips to mat. Should it nonetheless be necessary
to wash the cuff in water, the microphone must be removed and the air intake valve in the cuff closed off.
