I am measuring the in circuit current using a reference DMM as specified in the adjustment procedure in the DMM6500 Calibration and Adjustment Manual. The regular DCI adjustment steps work fine. However, the DIGI DCI steps report an error, with essentially the same value.

cal.adjust.step.execute(stepname, value)

cal.adjust.step.execute("cal_DCI_10uA_fs_pos", 1.0000105e-05)
cal.adjust.step.execute("cal_DCI_DIGI_10uA_fs_pos", 1.0000011e-05)

-222 Parameter data out of range

cal.adjust.step.execute("cal_DCI_10uA_fs_neg", -1.0000099e-05)
cal.adjust.step.execute("cal_DCI_DIGI_10uA_fs_neg", -9.999962e-06)

-222 Parameter data out of range

Hello,

I have confirmed there is a error in the manual as a 10uA current digitizer range does not exist on the DMM6500. This error has been submitted to get the documentation corrected.

This error is corrected in Rev. E of the DMM6500 calibration manual, available at<a href="https://www.tek.com/en/manual/digital-multimeter/model-dmm6500-6-1-2-digit-multimeter-0-dmm6500">&nbsp;https://www.tek.com/en/manual/digital-multimeter/model-dmm6500-6-1-2-digit-multimeter-0-dmm6500</a>
