2. UUT Select the correct range for the cal point.
3. 9100 a. Set Output ON.
b. Note the UUT reading.
4. UUT a. If a UUT calibration adjustment is provided, adjust the UUT
reading to be equal to that on the 9100 screen, as detailed in the
UUT Manufacturer's Calibration Guide.
b. If no adjustment is provided on the UUT, record the UUT
reading at the calibration point as detailed in the UUT
Manufacturer's Calibration Guide.
5. 9100 Set Output OFF.
