Thank you for your reply..

Yes may be you are right I have to check my device may be there is possibilities of fluctuations in voltage occurred from device it self.

And as a multiplexer I am using 34901A, and 34903A for a switching/relay.

Thank you very much once again for suggestions...

It sounds like you are on your way, you know you can always configure the instrument manually and have the measurements displayed on the 34970A.

Press the "Measure" button and set the function and range for the channel you are interested in.

Do this for each channel, notice if adjacent channels are the same type of measurements you can use the "Copy to channel" to copy the configuration. Saves a lot of button pressing

Then press the "Mon" button and the readings will be displayed on the 34970A, turn the knob to select the channel

For future reference...

The 34901A is a 20 channel ISOLATED multiplexer as you see each channel has it's own High and Low input.

The 34908A is a 40 Channel SINGLE ENDED multiplexer that means all the channels have a common Low input.

Hello,

I have check with 2 or 3 types of instruments and scan the channel 103 which I have given to the device and the thing is in many case during the scanning, value remain same means no fluctuation and on display of Vi I got 11v but I want less then 2v will you please tell me that which other data I have to check in datalogger.

Is there any changes I have to do in Datalogger??

How can I make sure that channel 103 is working correctly.??

Thank you very much for understanding.
