Calibration of 'UUTi High' Source Current Hardware Configurations
If both UUTi High and UUTi Low source current hardware configurations are being calibrated, the UUTi High source current
calibrations shown in Table 10.4.7.2 below should be performed before the UUTi Low source current calibrations.

Calibration Setup
1. Connections
Ensure that the 9100 is connected to the Standards DMM as shown in Fig. 10.4.7.1, and that both instruments
are powered on and warmed up.
2. 9100
Select the Resistance Function by pressing the '
Ω
' key on the right of the front panel.
Notes:
[1] This calibration point is limited by the maximum source current. If the actual source current is less than the indicated maximum, the output
value can be raised in inverse proportion. For example, a 50nA source current would allow the calibration point to be increased to 160M
