OPERATING MANUAL PAT-806 version 1.08

Connect the mains plug of the tested device into the test socket
of the meter. The measurement is made between shorted L, N
and PE. In addition, it is possible to carry out the measurement
with the probe connected to
R

socket.
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 10 A or 16 A 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. Then, it is recommended to perform a differential measurement of leakage
current.
- 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.
