Overview
To ensure the safe use of electrical products, it is necessary to conduct electrical safety tests such as
insulation resistance, withstand voltage, ground resistance, and leakage current.
Complying with laws and standards regarding medical electrical equipment as well as non-medical elec-
trical equipment, this instrument can be used to measure leakage current in all types of electrical prod-
ucts from computers to medical equipment. It consists of measurement networks that simulate the human
body and a high-frequency volt meter.
It is also capable of switching power supply polarities and making measurements under simulated single-
fault conditions in equipment under test.
To simplify leakage current testing, all test operations can be selected and run from a touch panel on the
display screen.
