Get your electronics set before getting the speciminIs it plugged in?Is it turned on?Check connectionsCheck grounds (plate to cage, cage to rack)Is your amplification correct? Check settings in handoutIs your scaling (time base and gain/voltage) correct?
You can check the connections and settings on the demo rig or on a classmate’s rig.
