KEW 8612

1. Instant Status LEDs
Get immediate visual feedback.
Clear live voltage presence indicators and real-time CP status.

2. CP Error simulation
Can be performed by pushing the CP Mode switch (spring loaded) into position [E].

2. CP Mode switch
Simulate EV states effortlessly by sliding the CP Mode switch to test states A, B and C.

A: Electric vehicle not connected
B: Vehicle connected, not ready to charge
C: Electric vehicle connected, ready to charge

3. Measuring terminals
PE, N, L1 (Single-phase)
PE, N, L1, L2, L3 (Three-phase)

4. CP signal output terminals
Terminals for measuring CP signals with oscilloscope, etc.

*Can be used with other insulation resistance testers, DMMs, etc.

Insulation test (for cable)
By connecting the test leads to the adapter terminal, the insulation resistance of cables can be measured for both single-phase and three-phase EVSE. (*Insulation measurement between wires (N, L1, L2, L3) other than PE is not possible.)

Earth Continuity test (200 mA)
It is possible to check continuity between the PE terminal of the adapter and the outer metal part or the earth of the electrical circuit.

Earth test (2-wire & 3-wire)
The resistance of the earth to which the EVSE is connected can be measured.

Voltage
Voltage/frequency between each terminal can be measured.

Phase rotation
Phase rotation of three-phase power supply can be measured.

Loop Impedance (Loop ATT function)
Loop impedance between Line-Earth can be measured.
Typical measuring instruments are designed to make Loop impedance measurements on circuits where RCDs are installed, at currents that do not trip the RCD, which is rated at 30 mA.
However, the 6 mA DC RCDs built into the EVSE often trip even at this current, so the KEW 6516 series has a dedicated EVSE range that measures Loop impedance at even lower currents.

RCD test
The EVSE's built-in 6 mA DC RCD can be tested for operation.
Polarity (+,-), ×1/2, ×1 and ×5 tests can be auto tested.
Type AC, A, B and F RCDs can also be tested.
