1.4 General Cautions
CAUTION
:
1. Avoid liquid splash and excessive temperature. The temperature must be kept
between 5
℃
and 40
℃
while working, and it should be kept between -20
℃
and
55
℃
during transportation & storage.
2. Do not use the equipment in dusty environment with bad ventilation or in the
presence of corrosive.
3. Be sure that there is no intense electromagnetic interference source around the
equipment, such as radio transmitter or mobile phone etc. Attention: large
medical electrical equipment such as electrosurgical equipment, radiological
equipment and magnetic resonance imaging equipment etc. are likely to bring
electromagnetic interference.
CAUTION
:
4. Before use, the equipment, patient cable and electrodes etc. should be
checked. Replacement should be taken if there is any evident defectiveness
or aging symptom which may impair the safety or performance.
5. The following safety checks should be performed at least every 24 months by a
qualified person who has adequate training, knowledge, and practical
experience to perform these tests.
a) Inspect the equipment and accessories for mechanical and functional
damage.
b) Inspect the safety relevant labels for legibility.
c) Inspect the fuse to verify compliance with rated current and breaking
characteristics.
d) Verify the device functions properly as described in the instructions for
use.
e) Test the protection earth resistance according to IEC/EN 60601-1: Limit
0.2 ohm.
f) Test the earth leakage current according to IEC/EN 60601-1: Limit: NC
500 uA, SFC 1000uA.
g) Test the patient leakage current according to IEC/EN 60601-1: Limit: 10
uA (CF).
