I am new to use Solid state relays (SSR). For my application i am using Panasonic 'AQV252G3' relay. i want to measure ON Resistance of this relay, according to the datasheet it ranges between 0.033 Ohm - 0.06 Ohm for A-type circuit connection.
i attached circuit diagram showing how my connections are with relay. i applying Load Voltage 5V/6V with Load Current 3.3 A (As suggested in Datasheet also LED Forward Current 5mA). When Relay is closed i measure voltage drop using DMM (its in the range of mV). Here I use Ohms Law V=IR to Calculate ON Resistance.
I use 5 relays, when i measure voltage drop for each relay it differs..
Is this measurement procedure correct?? if not can suggest improvements
