I am using a HRS-2 Series solid state relay. I am trying to determine whether I can use a simple continuity logger to determine when this relay is activated. I've attached the circuit from the data sheet below.
The idea is that I'd attach continuity leads between the trigger leads 1 and 2. The input circuit would already be wired up so that when power is applied to the input circuit I would hope it would be able to see that power was applied with my data logger on the trigger circuit 3 and 4. In practice however I'm not seeing any continuity between terminals 1 and 2 when the relays are turned on. These are dry contacts as of right now with no voltage going across 1-2.
