When connected via the 5-pole CEE mains plug (23), indicator lamps L1, L2 and L3 (19)
must light up. When connected via the earthing contact mains adapter (22), only indicator
lamp L1 should light up. Mains polarity is tested for this type of connection, i.e. if lamp L1 does
not light up, the polarity of the earthing contact plug must be reversed in the mains outlet. If this is not
the case, immediately disconnect the test case from the mains. The fault at the mains connection
or the test case must be eliminated before executing any further tests.
If the PE signal lamp lights up when you touch the contact surface (7), potential between the
protective conductor at the mains plug (22/23) and the contact surface (7) is
must light up. When connected via the earthing contact mains adapter (22), only indicator
lamp L1 should light up. Mains polarity is tested for this type of connection, i.e. if lamp L1 does
not light up, the polarity of the earthing contact plug must be reversed in the mains outlet. If this is not
the case, immediately disconnect the test case from the mains. The fault at the mains connection
or the test case must be eliminated before executing any further tests.
If the PE signal lamp lights up when you touch the contact surface (7), potential between the
protective conductor at the mains plug (22/23) and the contact surface (7) is
25 V, i.e. the
protective conductor is conducting voltage.
Note!
Depending upon handling, potential transfer may occur which causes the PE signal
lamp to light up. For example, this could be the case if you touch a device under test
with the NETZ-VDE switch (1) in the “VDE” position, thus creating a capacitive voltage
divider.

Attention
!
!
If, while testing protective conductor potential, you determine that the mains
protective conductor is conducting voltage, no measurements may be performed
with the test case. If this is the case, potentially dangerous voltage is also present at
the user accessible earthing contacts at the outlets, the “PE” socket (20) and the jack
(4). Immediately disconnect the test case from the mains and arrange to have the
fault eliminated at the mains connection. Voltage in the mains protective conductor
also results in incorrect measured values when testing for the absence of voltage in
accordance with DIN VDE 0701-0702 (see section 6.4.1).

Measuring Line Voltage
•
Set the measuring function selector switch (6) to “250 V~”.
•
If connected via the 5-pole CEE mains adapter, set the measuring selector switch (2) to
the L1, L2 and L3 settings, one after the other, and if connected via the earthing contact
mains adapter set the switch to L1 and read the measured value from the LCD panel for
each switch setting.
Line voltage must always lie within the permissible range of 207 to 253 V.

mains adapter set the switch to L1 and read the measured value from the LCD panel for
each switch setting.
Line voltage must always lie within the permissible range of 207 to 253 V.
Note!
If line voltage is present, values are displayed at the with the measuring function
selector switch (6) in each of its respective positions, even if no device under test has
been connected.
The display of such numbers indicates that line voltage is present, regardless of the
position to which the measuring function selector switch (6) has been set. If the
selector switch has been set to “250 V~”, these numbers represent the actual line
voltage value. In all other detented switch positions – if no device under test has been
connected – these numbers do not represent actual measured values.
If the test case has been connected via the earthing contact mains adapter, all tests and
measurements can be performed except tests at 3-phase current devices under mains
operating conditions.
