Test the safety and performance of a type 1, level 1 or level 2 electric vehicle ac charging stations (EVSEs) with the Fluke FEV100. This test adapter simulates the presence of an electrical vehicle, allowing you to conduct tests in combination with appropriate test instruments such as a digital multimeter or oscilloscope. Use the FEV100 to verify an EVSE is working properly after install and during periodic maintenance, or troubleshoot an EVSE if it is not delivering the appropriate charge.
Electrical safety
EVSE charging cables may become damaged over the course of use, increasing electric shock risks to users. Stay protected from and check risk of electric shock with the GFCI trip test. This function verifies the breaker of the EVSE is connected by detecting ground faults. Additionally, the PE grounding protection pre-test verifies that there is no presence of dangerous voltage at the ground terminal.
Simplicity and convenience
Perform a variety of tests including ground fault checks, insulation of wires, measuring voltage and duty cycle to see max current available for charging all in one adapter that safely integrates with the Fluke portfolio of test and measurement tools. There is no need to bring an electric vehicle onsite for EVSE troubleshooting: the adapter acts as an electric vehicle when connected to an EVSE for easy performance and maintenance testing.
Recommended tools for use with the FEV100

Key features
• Check protective earth for correct wiring and functioning with the PE pre-test feature.
• Perform GFCI troubleshooting of EVSE and verify operation within safety standards.
• Test charging states of EVSE with CP state simulation.
• Verify charging voltage and maximum available current using a multimeter.
• SAE J1772 compliant to North American standards.

Stakeless Testing
The Fluke 1623-2 earth ground tester is able to measure earth ground loop resistances using only clamps. With this test method, two clamps are placed around the earth ground rod and each are connected to the tester. No earth ground stakes are used at all. A known, fixed voltage is induced by one clamp and the current is measured using the second clamp. Then the tester automatically determines the resistance of the earth ground rod. This test method only works if a bonded earth ground system exists for the building or structure under test, but most are. If there is only one path to ground, like at many residential applications, the Stakeless method will not provide an acceptable value and the Fall-of-Potential test method must be used.
With Stakeless testing, the earth ground rod does not need to be disconnected - leaving the bonded earth ground system intact during test. Gone are the days of spending time placing and connecting stakes for each earth ground rod on your system - a major time saver. You can also perform earth ground tests in places you’ve not considered before: inside buildings, power pylons, or anywhere you don’t have access to soil.

The Most Complete Tester
The Fluke 1623-2 is a unique earth ground tester that can perform all four types of earth ground measurement.
• 3- and 4-Pole Fall-of-Potential (using stakes)
• 4-Pole Soil Resistivity Testing (using stakes)
• Selective Testing (using 1 clamp and stakes)
• Stakeless Testing (using 2 clamps only)
