5520A
Service Manual

3-30. Verifying Thermocouple Simulation (Sourcing)

Verify that the 5520A performance is within the limits in Table 3-30. Use the HP3458A
DMM as the measurement device. Use copper connectors and copper wires.
TC Type
10 V/ C

3-31. Verifying Thermocouple Measurement

Verify that the 5520A performance is within the limits in Table 3-31. Use a Fluke 5500A
Calibrator or similar instrument as the millivolt source, connected in parallel with an
HP3458A DMM. At each verification point, use the 5500A error mode controls to adjust
the calibrator output for a nominal reading on the DMM. Use copper connectors and
copper wires.
