DPI 841/842 with these conditions:
Output Hz = 0 (For direct current output)
Output amplitude: Set to Unipolar (Table 5)
8. Supply the specified values (Table 13): Square Wave
then Sine Wave. Make sure that the error is in the
specified limits.

Calibration - Procedures (IDOS UMM)
Refer to the user manual for the IDOS UMM.
When the calibration is complete, the instrument
automatically sets a new calibration date in the UMM.
