Measurement considerations
For sensitive measurements, follow these guidelines to
maximize measurement accuracy:
• Use only clean, copper-to-copper connections to minimize
thermal EMFs.
• Any solder connections should use silver solder to minimize
thermal EMFs.
• Clean all connector terminals of oxidation using a small
amount of DeoxIT.
•
Use the relative offset (REL) to null out offsets:
• Connect the circuit, but leave the source disconnected.
• Select DCV1 or DCV2 as appropriate.
•
Press REL to null offsets.
• Repeat for other channel if needed.
• Connect the source, and make the measurement.
• Keep the 2182A and test circuit away from electrical noise
sources, and shield if necessary.

Model 2182A Nanovoltmeter User’s Guide
