8-4-3-4 Leakage current
#
IMPORTANT
#
As SSD-ALPHA10 has hard disk drive inside, when you measur ethe
leakage current by using the leakage current tester that has automatic
measurement function such as “HIOKI 3156 LEAK CURRENT
HiTESTER”, do not use this automatic function. Because this function
automaticaly change the polarity of input voltage during the equipment
is running. It will be cause the damage on the hard disk drive.
Therefore when you measure the leakage current with above tester,
change the measurement condition after turning the equipment Off
manually.
"
Earth Leakage Current
Earth leakage current must measure with STAND-BY condition.
"
Enclosure Leakage Current (a) (Between the enclosure and the earth)
Enclosure leakage current (a) must measure between top cover of the unit and the earth.
"
Enclosure Leakage Current (b) (Between the enclosures)
Enclosure leakage current (b) must measure between top cover of the unit and the
monitor.
"
Patient Leakage Current I
There is no supplemental information about this.
"
Patient Leakage Current III
There is no supplemental information about this.
"
Patient Auxiliary Current (OPTION: with the PEU-ALPHA10* connected)
Patient auxiliary current must measure between ECG black lead and other ECG leads
that band red and green together.
