Measure with a Keithley3706A without switching?

[Kauzig]

Hi

I have got a Keithley 3706A. It works pretty well to measure with LV.

I have to measure the same channel for several times. I managed this without any troubles but they relay is always switching for no reason.

Cause this relay has a lifespan it will be a big problem after some hours, so I'm searching for a simple solution to measure one channels for x times without switching.

 

Hope some one can help me.

 

sincerely

Usually these instruments operate relays when they switch ranges, which happens for instance when you measure in some autoscale mode; or when ouputs are activated; both can be avoided for continuous measurement with a proper approach (e.g. -- determine the proper range once and repeat a fixed range measurement then). As such your question is instrument and not LV specific.
