MSP430i2040 DC Measurement Issues

$

Hello,

I recently purchased the MSP430i2040 and followed all the calibration procedures. The AC values are fine. However, when I hook up a 0-120 DC source the values are off by a random amount. I tested at 40V 60V and 120V with the same issues. Any suggestions on how to receive accurate DC readings up to 120V? Actual Multimeter Values are 344.3 mA at 120.1V

Thank You
