In order to help craftspeople transition to high-efficiency pumps, the solar controller manufacturer Resol is offering a new testing tool. The device, which is called HE-Check, is specially designed to determine whether a fault is caused by the controller or the pump.

For this purpose, HE-Check can generate and measure PWM signals in the 290 to 2000 Hz range as well as 0-10 V signals. To test bi-directional pumps, the device can also simultaneously generate and detect PWM signals. In addition, HE-check displays the volume flow and pump status on a graphic display. It includes a versatile set of measuring and signal connections for various pumps and controllers.

Power is supplied by three AAA batteries. Resol expects an average battery life of about two years. The casing is made of ABS and TPE plastics and achieves protection class IP 54 (DIN EN 60529).
