Note
Measurements and measurement series can only be
saved after measurement has been completed. Mea
-
sured values can only be added t
o intermediate buffer
memory during a measurement. Customer, location and
other entries cannot be changed in the memory menu.
These have to be selected directly in the database and
entered or changed.
Note
Please observe the following before storing tests or measure-
ments to the test instrument:
The date of recalibration may be printed on test reports or
transmitted to a PC during the export of test data. We
therefore recommend that you check the recalibration
date saved in the test instrument before starting to work
with your new test instrument (see page 12).

Application, Definition, Measuring Method
Protective conductor resistance is the sum of the following resis-
tances:
• Connector cable or device connector cable resistance
• Contact resistance at plug and terminal connections
• Resistance of the extension cord if applicable
Protection Class I Devices

easurement type PE(TS) - P1 (passive)
– DUT mains plug to test socket
– Test probe P1 to P1 terminals
Schematic Diagram
Protective conductor resistance is measured between the earth-
ing contacts at the mains plug and the ea
rthing contact con-
nected to the housing by contacting th
e housing with test probe
P1.
