4-17. Cable Connection Instructions

Table 4-2 indicates a figure reference for each type of connection between a UUT and
the 5500A Calibrator, referencing Figures 4-1 through 4-10.
When calibrating Resistance Temperature Detectors (RTDs) using the three-terminal
connection shown in Figure 4-9, be sure the test leads have identical resistances to
cancel any errors due to lead resistance. This can be accomplished, for example, by using
three identical test lead lengths and identical connector styles.
When calibrating thermocouples, it is especially important to use the correct hookup
wire and miniconnector between the Calibrator front panel TC jack and the UUT. You
must use thermocouple wire and miniconnectors that match the type of thermocouple.
For example, if simulating a temperature output for a K thermocouple, use K-type
thermocouple wire and K-type miniconnectors for the hookup.
To connect the calibrator to a UUT, proceed as follows:
1. If the calibrator is turned on, press
terminals.
2. Make the connections to the UUT by selecting the appropriate figure from Table 4-2.
3. For capacitance outputs, null out stray capacitance by connecting the test leads to the
UUT, routing them (but not connecting) to the 5500A Calibrator on a non-
conductive surface. Null out the reading on the UUT using "rel," "offset," or "null,"
whichever method applies, and then connect the test leads to the 5500A Calibrator.
