Checking the patient leakage current III
(1) Measurement wiring diagram
(2) Patient leakage current III measurement points
Measurement Point A
All sensors (Short all electrodes.)
Measurement Point B
Resistance 10 k
Ω
connected to one insert of the conversion
plug (protective resistance)
Place the MD in between measurement point A and B.
(3) Patient leakage current III measurement conditions
To measure the patient leakage current III, it is necessary to change the power phase under
the single fault condition. Consequently, total of two measurements should be carried out to
measure current in all conditions.
(4) 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.
Single fault condition
0.05 mA or less
VS-1500
All Sensors
