Maintenance of the HS112 C-1
3.1. Regular and periodic maintenance
The
HS112 C-1
is a low-maintenance device.
Always make sure that the device and its accessories are clean and free from damage. After
use, the electrodes have to be cleaned from gel and other materials that might have stuck to
them. The condition of the electrode cables has to be checked regularly, making sure there is
no damage (cable insulation, breakage).
Battery status has to be monitored. If the device indicates that the battery is close to being
discharged, it has to be connected to the mains power supply.
After several years of use, the capacity of the battery may decrease to the extent that it is not
able to perform a 4-hour monitoring when fully charged. In this case, battery replacement is
recommended. The replacement should only be done by qualified experts.
Occasionally (every 1-2 years), the main parameters of the electrocardiograph should be
checked and, if need be, the settings should be adjusted. This should only be done by a
qualified service technician.
Accidental or random pressing of the buttons cannot cause failure.
Interact with the screen only using your fingers! Do not use any tools or instruments.
The expected lifetime of the device is 8 years. The expected lifetime of the battery depends
strongly on use, but it averages at approximately 3 years.
In the service documentation, the manufacturer provides the circuit diagram, accessory list,
descriptions, calibration instructions, and other information about reparable parts relevant to
the service technician.
3.2. Cleaning, disinfection
A formaldehyde solution can be used to clean and disinfect the device. The device can be
cleaned using a cloth with a mild solution of detergent and water, and then disinfected with
the formaldehyde solution. The formaldehyde should form an even, continuous liquid film on
the surface of the device, and then be allowed to dry. While cleaning, make sure that no liquid
gets into the device or the paper tray. The electrodes can be cleaned and disinfected with
alcohol or even with a formaldehyde solution. As formaldehyde has an unpleasant smell, and
can cause skin and mucous membrane irritation, wearing rubber gloves while cleaning is
advised. After finishing, air the room thoroughly.
To make the disinfectant formaldehyde solution — for 1000 cm
3
of liquid, dilute 50 cm
3
of
35–40% formaldehyde solution with distilled water.
