FORM RELAYS-MAINTENANCE · V5
Engineer name

Work scope & measurement context (optional record fields)

References only. This site supplies no acceptance values, test settings, intervals or release instructions. Selecting a scope does not authorize work. Use Remarks for row-specific context; refer to original files, which are not uploaded here.

Draft · technical review pending. Recording prompts only; not procedures or acceptance criteria. Work and access require your approved plan. No normal ranges, pass/fail values, test settings or maintenance intervals are supplied. Condition results are user-entered judgements under separately approved criteria. Evidence/task/measurement OK means the specified record is complete, not healthy equipment. This checklist does not authorize release to service. Unit selection does not convert values.

Archived V5 — read-only access to earlier saved records. No automatic migration. Export JSON or CSV for backup.

How to read this form

Condition
OK = User assessment under the referenced approved criteria.
Measurement record
OK = Required measurement record and context are complete.
Evidence check
OK = Required reference or evidence is verified.
Task record
OK = The specified recording task is complete.
Blank / Pending / N/A
Blank is unclassified. Pending identifies missing checks, evidence or criteria. N/A needs a reason in Remarks.

No row or completed form certifies safety, compliance or fitness for service.

Engineer/date/signature spaces remain for handwriting. Multiple records can be saved locally in this browser and exported; no cloud backup, file attachments or team approval is provided. Older template records stay separate and are not reinterpreted. Keep sensitive information off shared devices.
