Harmonic filters Maintenance Checklist
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.

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.
