# Multimeter reading log

Paste field readings as CSV with expected values and tolerance bands to get a pass or fail table, deviation stats and findings, plus CSV or JSON export.

Paste readings as CSV, then press Check readings.

Bands are inclusive at both ends. When a row has both a tolerance and an explicit Min/Max, the explicit band wins. Deviation runs against Expected, falling back to the band midpoint when Expected is blank, which is why a wide Min/Max row can show a large deviation percent on a passing reading. A row with an Expected but no tolerance and no band is recorded as unbanded, not judged against a guess. The meter and calibration reference ride along on every export; nothing leaves this tab.
