5.1 General Procedure
Ð Select the main menu: MENU key.
Ð Select a menu function: ↑↓ keys.
Ð Depending upon the measuring function select either
– Type of test current: DIR / DIF / ALT / DL key.
or
– Protection class and type of connection: PC1 / PC2 / FIX key.
Ð Connect the device under test in accordance with the
previously selected type of test current.
Depending upon the type of test current, it may be necessary to
use the probe.
The device under test is checked for short circuiting for all active
measurements during which the mains are connected to the test
socket (e.g. for leakage current measurements).
Ð Start the test with the STARTSTOP key.
During measurement, a symbol representing a runner appears
at the upper left-hand corner instead of the measurement icon.
During measurement and after the measurement has been com-
pleted, measurement data can be read from the display.
Ð If necessary, repeat the test with reversed mains power
polarity: L/N N/L key.
Ð The display is returned to the main menu by pressing the ESC
key or the MENU key.
