13.3 The 9100 as an Adjustable 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) .
13.3.1 9100 and UUT Setup
1. Connections
Connect the 9100 to the UUT as in
Fig. 13.1 , and
ensure that both instruments are powered ON
and warmed up.
2. UUT Select Capacitance function.
3. 9100
Ensure that the 9100 is in Capacitance Function
with Output OFF. If in any other function, press
the 'Aux' key on the right of the front panel, then
press the screen key on the bottom row.
13.3.2 Sequence of Operations
Refer to the table of UUT calibration points in the
Manufacturer's Calibration Guide for the UUT. Follow
the sequence of calibration stages as directed by the
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 capacitance to the UUT cal point value,
selecting 2-Wire or 4-Wire and 'UUTi' Current
Span as required.
2. UUT Select the correct range for the cal point.
3. 9100
a. Set Output ON.
b. Slew the Capacitance Output reading until
the UUT reading is equal to the calibration
point value.
4. UUT
Record the 9100 screen output value as detailed
in the
UUT Manufacturer's Calibration Guide .
5. 9100 Set Output OFF.
