Gossen Metrawatt PROFITEST H+E EXPERT CHECK tester for AC charging stations

Gossen Metrawatt’s PROFITEST H+E EXPERT CHECK is a diagnostic tester corresponding to measurement category CAT III 300 V for standard-compliant functional testing of AC charging stations in accordance with DIN EN/IEC 61851-1 (VDE 0122-1). The handheld tester enables electricians to test the functionality, electrical safety and personal protection of single- and three-phase AC charging points in charging mode 3 on a type 2 socket or a permanently connected type 2 cable.

The device provides standard-compliant testing of PE interruptions with a graphical display of measured values. Its functional range includes the verification of vehicle states A, B, C and D; phase tests and phase sequence tests; diode testing; and evaluation of the PWM signal for data communication. It aborts the charging process during short-circuit simulation and determines battery charging levels.

In combination with installation testers from the PROFITEST MF or PROFITEST MASTER IQ series, the device can also be used as a test adapter for electrical testing of charging infrastructure thanks to its measuring inputs and earthing contact socket. In addition to the charging function tests, relevant safety tests can also be carried out in this combination, including low-impedance continuity of the conductors, insulation resistance, tripping of the residual current circuit breaker (RCD/FI), 6 mA sensors, and loop and internal mains resistance. Measured values and test results are shown in plain text on the device display.
