1 Want command to check whether SR830 lock-in amplifier is overloaded or not

[physics.department100]

Actually I want to know the coding for detecting whether the SR830 lock-in amplifier is overloaded or not. I have searched it in SR830 manual but can not find it. Can anyone help me regarding this ?

For something this specific, you should ask the vendor - http://www.thinksrs.com

That information is returned in the LIA status byte (pg 5-23 of the manual). You can use the LIAS? command to query that byte, or if you want, you can set the instrument up to generate a device request when one of the overload bits flips and then monitor for the SRQ.
