Issue Details

I would like to measure negative DC voltages with the PXI-4065 digital multimeter card. If it is possible, what is the measurement accuracy in the negative signal range? I can't find any information regarding this in the product's datasheet.

Solution

The voltage measurement range of the PXI-4065 module is in general symmetrical to zero, so it can measure both positive and negative voltages. Moreover, the measurement tolerances have been defined independently of the polarity of the voltage, so they are valid for both positive and negative input voltages.
