□
Earth Leakage Current Test
Connect the 601 safety analyzer to the AC
power supply.
Connect the applied part of the tested
device to the RA end of the safety
analyzer.
Connect the tested device to the auxiliary
power output socket of the 601 safety
analyzer through a power cable.
Plug in the 601 safety analyzer, and press
4-Earth leakage on the panel of the safety
analyzer to access the earth leakage
current test page.
Normally, the earth leakage current is not
greater than 500 μA. In case of a single
fault, the earth leakage current is not
greater than 1000 μA.
□
Occlusion alarm
Check method: Select right
brand IV set, and set the
infusion rate to 120 ml/h. Set
the occlusion level to P6. Start
the
infusion
and
check
whether the following alarm is
generated within 1 minute:
Syringe occlusion is displayed
on
the
screen,
the
“di-di-di…di-di” alarm sound
is given every 15 seconds, and
the
red
alarm
indicator
flashes.
□
Check the appearance of
the power cable. If a surface
damage or poor contact
between plug and socket is
found,
maintenance
is
required
□
Patient Leakage Current Test
Connect the 601 safety analyzer to the AC
power supply.
Connect the applied part of the tested
device to the SUM end of the process
equipment and the RA end of the safety
analyzer.
Connect the tested device to the auxiliary
power output socket of the 601 safety
analyzer through a power cable.
Plug in the 601 safety analyzer, and press
6-Patient leakage on the panel of the
safety analyzer.
Press APPLIED PART repeatedly to
select AC or DC measurement. When DC
is selected, DC is displayed behind the
limit value.
Normally, the patient leakage current is
not greater than 10 μA. In case of a single
fault, the patient leakage current is not
greater than 50 μA.
