Performance Verification
• Verification test requirements — Summarizes environmental conditions, warm-
up period, and line power requirements.
• Recommended test equipment — Lists all equipment necessary for verification
and gives pertinent specifications.
• Verification limits — Describes how reading limits are calculated and gives an
example.
• Calibrator voltage calculations — Details the method for calculating calibrator
voltages when testing the 2nA to 2µA ranges.
• Performing the verification test procedures — Summarizes test considerations
and describes how to restore factory defaults.
• Offset voltage calibration — Lists steps necessary to null voltage offset before
performing verification.
• Current measurement accuracy — Lists detailed steps for verifying measure-
ment accuracy of all current ranges. The 2nA to 2µA and 20µA to 20mA ranges are
covered separately because of the different test equipment required.
