All sensors (Short all electrodes.)
Measurement point B
Earth terminal of power outlet
Place the MD in between measurement point A and B.
(3) Patient leakage current I measurement conditions
It is necessary to measure the patient leakage current under two conditions: normal
condition and single fault condition.
(4) How to reproduce a single fault condition
You can reproduce a single fault condition by connecting the conversion plug to the power
outlet with the earth wire not connected.
How to change the phase
You can switch the phase by inserting the conversion plug into the power outlet upside
down.
(5) Acceptance standards
Check that the maximum current value meets the following judgment criteria.
Normal condition
0.1 mA or less
Single fault condition
0.5 mA or less
