Voltse() and The voltage range


kokihualpa Dec 27, 2020 04:38 PM

Dear

I see that when I connect one instrument in one Single ended (SE1,SE2...) and that equipment works in a range of 0-5VDC.

That instrument works equal if I put in the section "Range", +-2500 or +-5000 mv. So in reverse, one equipment of 0-2.5VDC, works equal if I put "Range" in +-2500 or +-5000 mv.

Why? That range is not supose has to restrictly.

The 5VDC signal from the sensor is more than 2500mV more than the voltage on the ground of the datalogger. Ground voltage on the datalogger will be at 0VDC.

The +-5000mV range must be used.
