Hang on, they may be OK.
The SCM30 is actually a number of series connected diodes in one package.
The datasheet gives the forward voltage drop as up to 15v at 10mA, so a normal DMM diode test/Component tester will show a good device as open circuit.
An AVO on the ohms x100 range or an 18v battery and series resistor (1k8 upwards) would work.
