OPERATING MANUAL PAT-800/805 version 1.09 33
Settings and the measurement are as in 4.5.1.
Notes:
During the measurement in the test socket the voltage of mains is present.
During the measurement of a faulty device, RCD switch may be triggered off.
- PE leakage current is measured directly on this line enabling the user to get precise measurement
results even when the device consumes 10A or 16A current. Note that if the current leakage is not
caused by PE line but by other earthed elements (e.g. water pipe)
– it cannot be measured in this
measurement function.
- Ensure that the location of the tested device is isolated.
- Tested device must be turned on.
- In the half-time of the measurement, the meter automatically changes the polarity of the test socket
and as a result it displays the value of higher leakage current.
