The opening of the instrument for fuse replacement,
for example, may only be carried out by professionals.
Prior to opening, the instrument has to be switched off
and disconnected from any current circuit.
The instrument may only be used under those condi-
tions and for those purposes for which it was conceived.
For this reason, in particular the safety references,
the technical data including environmental conditions
and the usage in dry environments must be followed.
When modifying or changing the instrument, the operation-

2.1 Intended use / Use for intended purpose
The METRALINE EVSE IT is a test adapter (accessory) to
support all relevant measurements of the METRALINE MF.
It is connected between the EVSE charging point (Type-2
connector) and the measurement inputs of the METRALINE
MF. All wires of the charging connector are available: L1,
L2, L3, N, PE, CP and PP.
This allows to perform typical measurements: voltage, fre-
quency, phase indication, phase sequence, various RCD
tests and measurements, insulation resistance, low ohm
measurements, line and loop impedances, etc.
Safety of the user, as well as that of the instrument, is only
assured when it’s used for its intended purpose.
2.2 Use for other than intended purpose
Using the instrument for any purposes other than those
described in these instrument operating instructions is con-
trary to use for intended purpose. Use for purposes other
than those intended may result in unforeseeable damage!
2.3 Liability and guarantee
The warranty provided by Gossen Metrawatt GmbH, and
its liability, are governed by the applicable contractual and
mandatory statutory provisions.

1. Connect the needed 4 mm test leads of the METRALINE
EVSE IT to your METRALINE MF.
2. Select CP mode “A” with the slider switch.
3. Connect METRALINE EVSE IT to the Type 2 connector
4. Select CP mode “B” with the slider switch, the charging
point should show “ready to charge”.
5. Select CP mode “C” with the slider switch, the charging
6. Perform all measurements in active stage of the
charging point (voltage and similar).
Refer to the METRALINE MFproduct documentation.
7. After you completed all your measurements
select CP Mode “A” with the slider switch to stop
8. Unplug METRALINE EVSE IT from the charging point.
5.2 Proximity Pilot (PP) state (cable simulation)
The METRALINE EVSE IT is designed in such a way
(220 Ω between PP and PE) that it provides a 32 A current
5.3 Control Pilot (CP) state (vehicle simulation)
Using the CP mode slider switch, various vehicle states can
be simulated. Vehicle states are simulated through different
resistances connected between CP and PE conductors.
The correlation between resistance and vehicle states is
shown in the table below.
5.4 CP Signal output terminals
The CP output terminals are short connected to the CP
and PE conductors of the tested charging station via the
test cable. Use an oscilloscope to check the waveform and
amplitude of the CP signal.
The Control Pilot function uses Pulse Width Modulation
(PWM) to code communication between a vehicle and
charging station. The duty cycle of the PWM signal denes
the possible available charging current, while the amplitude
denes the charger state.
For details of the communication protocol refer to DIN EN
IEC 61851-1 and the manufacturer’s documentation of the
If the charging station is wired incorrectly,
low signal CP test terminals may receive high,
life-threatening voltage.
5.5 CP Error “E” simulation
The “E”-CP error simulation can be realized by pushing
the slider switch into (spring loaded) position [E]. This will
simulate the behaviour of a charging station when there is a
short circuit between CP and PE through the internal diode
(acc. to DIN EN IEC 61851-1).
In case of an CP error (“E” is pushed), the expected result
is an abortion of the charging process and a new charging
The measuring terminals (no. 1 and 2 in the device over-
view) are directly connected to the L1, L2, L3, N and PE
conductors of the tested charging station.
The measuring terminals must only be used for
measurements. It is forbidden to draw current over a
longer period or supply anything else.
An appropriate measurement instrument is required.
