Heating Instruments - Solid State Relay Instruction Sheet

This article provides instructions for testing a Solid-State Relay (SSR) in Heating Instruments. It explains why a voltage tester cannot be used to check an SSR and provides a step-by-step method for testing the SSR using a heater load. The instructions include verifying the 3-32VDC on the input side and measuring voltage changes on the output side to determine if the SSR is functioning correctly.
