Set the parameter
TestMode to Off after completing these tests. The
Start LED stops flashing when the relay is no longer in test mode.
An initially high contact resistance does not cause problems as it is reduced quickly by the
electrical cleaning effect of fritting and thermal destruction of layers, bringing the contact
resistance back to the mOhm range. As a result, practically the full voltage is available at the
load.
