Hello, I am trying to get the induced emf reading from a sample in a vsm. A lock in amplifier is being used to read the signal. The problem is that the output voltage fluctuates heavily. Should I apply an audio amplified signal to my sample to make it vibrate ?

I am measuring voltage output from the pick-up coils of a vibrating sample magnetometer using the SR830 lock-in amplifier. The problem is that the channel 1 output voltage cannot be stabilized at all. I read the manual but that is not helpful either. What can I do to stabilize the reading ?
