The [PE -> 5.0 m] button determines the length of the test object’s
connecting cable. With every press on this button the value is increased by
a further 7.5 m. The resulting limit value for the maximum protective
conductor resistance (see below) is visible in the limit values line.

With the function button [Hand/Auto] you determine whether the test
procedure should be carried out manually (by hand) or automatically.

Manual test procedure means that you have to confirm every test
stage by pressing the [OK

] button to get to the next test stage

.

Automatic test procedure means that a test stage automatically
changes to the next after 5 seconds - except for confirmation of
connection to the mains voltage (see Point 6.6, basic settings of
the tester).

The headline shows the setting for a manual [H] or automatic [A] test
procedure. The [Cancel] button takes you back to the ‘Main menu’. To
move to the next stage press the [Next] button (also see Diagram 1 in Point
9.8).

If in the ‘Configuration menu’, direct measurement is set as the
measuring method for the protective conductor current, the
following warning message appears in the display: ‘ATTENTION!
The test object must be insulated during the following test stages!’.
Please follow this instruction without fail; otherwise the protective
conductor current cannot be measured correctly.

The [->Next] button takes you to the first stage of the test: the visual
inspection (Fig. 15). The housing, connecting cable, inscriptions and other
parts should be inspected in this test. You confirm positive results of the
visual inspection by pressing the appropriate buttons – the display changes
from ‘not OK’ to ‘OK’ (Fig. 16).

The limit value is:
0.3 

Ω for devices with connecting cables up to 5 m,

plus 0.1 

Ω for every 7.5 m, but only up to a maximum of 1.0 Ω
