far-field interference appears on
screen.
1. Check power supply (spark interference present).
2. Check environment (source of interference around the
machine, such as electric motor, ultrasonic atomizer,
automobile, computer or other interference).
3. Check power plug/socket of the instrument. They shall
be properly contacted.

8.4 Periodic Safety Checks
To ensure the system performance and safety, it must be checked after using 1 year. When
check the instrument, please consult the International Trade Dept of Kaixin or its dealers, as they
need to have professional technology engineers.
1. The following safety checks should be performed at least every 12 months by a qualified
professional engineer who has adequate training, knowledge, and practical experience to
perform these tests.
Inspect the equipment and accessories for mechanical and functional damage.
Inspect the safety relevant labels for legibility.
Inspect the fuse to verify compliance with rated current and breaking characteristics.
Verify that the device functions properly as described in the instructions for use.
Test the protection earth resistance according to IEC 60601-1: Limit: 0.1Ω.
Test the earth leakage current according to IEC 60601-1: Limit: Normal Condition
500μA, Single Fault Condition: 1000μA.
Test the touch current according to IEC 60601-1: Limit: Normal Condition 100μA,
Single Fault Condition: 500μA.
Test the patient leakage current according to IEC 60601-1: Limit: Normal Condition
for a.c.: 100μA (B), for d.c.: 10μA (B), Single Fault Condition for a.c.: 500μA (B), for
d.c.: 50μA (B).
The leakage current should never exceed the limit. The data should be recorded in an
equipment log. If the device is not functioning properly or fails any of the above tests, the
device has to be repaired.
2. Please clean the plug of power cord at least once a year. Too much dust on plug may cause
