Re: IviDmm sample code

I am trying to use an IviDmm driver for the first time with a Keithley 2110 DMM.  Once I read from the DMM the display keeps the value displayed whether there is voltage present or not.  How do you allow the DMM display to remain live?  Is there some example code that i could look at regarding the initialization and use of the DMM?
Thanks

Re: IviDmm sample code

IviDmm.prj in the ATEasy Examples directory contains an example of how use the IviDmm driver.  Is the DMM Read() command causing the frozen display?  Does a reset clear it?

Re: IviDmm sample code

Thanks for the location of sample code.  After the DMM Read() the display freezes, a reset will clear all settings.  Also, using DMM Set Range AutoOn() doesn't allow it to auto range.  I'm using the 'Ke2100-x86' driver.

Re: IviDmm sample code

It sounds like its not returning to the Idle state after a IviDmm_Read is being called.  This may be standard behavior.  A call to DMM Abort() will abort the current measurement and return you to the Idle State but you will want to make sure the measurement has completed.  In addition, there is another driver / example that you can use.  Please look at Ki210x.prj which is also in the ATEasy Driver folder.
