🧰 Equipment Reference-Check Log

🧰 Equipment Reference-Check Log

Record a pre/post-session check against a known reference for each instrument. Enter the manufacturer’s stated tolerance yourself; this page does not invent calibration limits or certify a device.

FIELD CHECK ≠ CALIBRATION CERTIFICATE
Use a traceable reference where possible and follow the instrument manual. A result “within entered tolerance” only means the numbers you supplied meet that comparison.
Enter a reference, a reading, and the tolerance from the instrument specification.
