• Alternative leakage current measuring method
– Protective conductor current, contact current, device leakage current, patient leakage
current
• Differential current measuring method
– Protective conductor current
– Device leakage current
• Direct current measuring method
– Contact current
– Patient leakage current
• Functional test (power consumption and current consumption of the test sample cannot be
determined)
• U welding equipment (ST 760+)
a
• PRCD
The test procedures 17 - 22 [} page 102] included in the device represent automatic test
procedures for using the BENNING MA 4.
