As a new Siemens product I suppose I will not have to be prejudice against it on the basis of past issues with Crabtree and Wylex devices.
The test button is on the red light at the bottom of what you see when the CU cover is fitted.
I'm not sure how you ho about testing a circuit with a four in one protective device, I presume you would start with an insulation test to see if the RCD or MCB element are tripping it.
