Calibration Adjustment
The Meter features closed-case calibration adjustment with a known reference source.
The Meter measures the applied reference source, calculates correction factors, and keeps
the correction factors in nonvolatile memory.
Before you start calibration adjustment, let the Meter stabilize to room temperature.
