Shell Leakage Current Test
1Connect 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.
Connect one end of the red test lead to the
red input terminal of the safety analyzer
and clamp the other end of the red test
lead onto the metal foil attached to the
shell of the tested device.
Plug in the 601 safety analyzer, and press
5-Enclosure leakage on the panel of the
safety analyzer to access the shell leakage
current test page.
Normally, the shell leakage current is not
greater than 100 μA. In case of a single
fault, the shell leakage current is not
greater than 500 μA.

Check air bubble sensor
Check method: make a 3mm
air bubble in the tube, then set
a speed to infusion; it would
