Figure 5.33: Examples of touch leakage current measurement results
Displayed results:
Main result I ........... Touch leakage current
Sub-result P............Apparent power
Notes:
 For this test the instrument must be connected to the mains voltage.
 During the test, mains voltage is connected to the DUT. If DUT contains moving
parts, make sure that it is safely mounted or protected to prevent possible danger to
the operator or damage to the DUT or surrounding environment!
Consider any displayed warning before starting measurement! 
5.2.10 (P)RCD test
The purpose of this test is to ensure the proper operation of residual current devices
(RCD) built into appliances / installations and portable residual current devices (PRCD).
Trip-out time measurement verifies the sensitivity of a (P)RCD at selected residual
currents.
The (P)RCD test is performed via the instrument mains supply input.
