Lower Display Thermocouple Source Test
1. Set the 5520A to measure Type-J thermocouple voltages.
2. Press M on the UUT until SOURCE appears on the lower display. If necessary,
press T on the UUT until J appears on the lower display and press D (use the
configuration menu on the 726) so the temperature is displayed in °C.
3. Use the arrow keys to set the UUT outputs to the temperatures in Table 14 and verify
that the 5520A temperature readings are within the limits shown.
4. Press STBY on the 5520A. Remove the TC lead from the 5520A and the UUT.
