3.2 The 9100 as a Fixed Source
The following procedure assumes that the instrument
is in Manual Mode. In case of difficulty, read the
User's Handbook; paras 3.3.1 . Familiarity with editing
screen values is also assumed (Section 3) .
3.2.1 9100 and UUT Setup
1. Connections
Connect the 9100 to the UUT as in Fig. 3.1 , and
ensure that both instruments are powered ON
and warmed up.
2. UUT Select DC Voltage function.
3. 9100
Ensure that the 9100 is in DC Voltage Function
with Output OFF. If in any other function, press
the 'V' key on the right of the front panel.
3.2.2 Sequence of Operations
Refer to the table of UUT calibration points in the
Manufacturer's Calibration Guide for the UUT. Follow

guide, and carry out the following operations (1) to
(5) at each stage.
1. 9100
Use the front panel controls to set the 9100
Output voltage to the UUT cal point value,
entering High Voltage State if the cal point has
been assigned to that state.
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
