Maintenance and fault clearing
8.1
Checking the measuring technology
The unit’s measuring technology should be checked every 24 months. The following checks should be
performed in the process:
1.
Check of the ergometer's overall mechanical condition
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 blood pressure recorder's pressure measuring unit
8.
Check for tightness of the pneumatic system
9.
Check of the safety symbols and markings on the casing
10.
Writing of an inspection report
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
cleaning agents for household appliances can be used. The saddle should be cleaned with a leatherette
cleaner.
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
The blood pressure cuff consists of a waterproof plastic foil. It can be cleaned with soapy water and a
cloth. The water temperature must not exceed 30 °C. The cuff should not be plunged into suds to clean,
as the Velcro straps might mat. If it should nevertheless be required to wash the cuff in water, the mi-
crophone must first be removed and the air admission pipe must be closed.
8.4
Checking and setting the supply voltage
On delivery, the unit is set for the local supply voltage (110/115 ~ or 230/240 V ~). The current voltage
setting is recorded on the mains module. The power unit covering lid on the bottom of the unit must be
opened to convert the voltage. The voltage can then be changed on the power unit on-board with a spe-
cial voltage selector switch.
Voltage conversion should only be performed by authorised and trained personnel.
