Interconnections

Section 4, sub-section 4.2 of the User's Handbook
gives details of the Model 9105 Leadset and
Workmat, used for connecting the 9100 to the UUT.
This Section repeats the User's Handbook
information appropriate
interconnections.
2.1 External Leads —
Specification Degradation
The 9100 Accuracy Specification is delivered at the
front panel terminals.
Degradation of the specification at the UUT can
occur if care is not taken to select the correct type,
length and terminations for the external leads. This
applies particularly to the outputs of HF AC Voltage
at milliamp levels and HF AC Current. In addition, for
accurate thermocouple simulation, extension leads
of the correct materials must be used to avoid
forming spurious junctions.
2.2 Model 9105 Lead Set
The design of the Model 9105 optimizes the
connections between 9100 and UUT, in order to
minimize the specification degradation for the outputs
of all functions. In addition, it provides a convenient
screened work mat which permits easy connection
to the UUT using leads of defined short length, which
are also provided.
It is highly recommended that the 9105 Lead Set be
used for all hand-held UUTs.
2.3 Connection Accessories
Two accessories are available to connect with the
9100/9105 for specific purposes:
• For thermocouple software compensation, an
external module can be plugged into a 15-way
D-type socket, either on the 9100 front panel or
on the connection unit beneath the 9105.
• A pair of coils is available (Option 200) to permit
clamp ammeters to be calibrated at high currents.
