Manual readings must describe the measurement actually made under the approved check. Have the confirmed unit, instructions and required reviewed instrument ready. CheckStation does not acquire readings automatically from an instrument.
Read before entering
On the active attempt, inspect the selected check's instructions, acceptance limits, unit and required repetitions. Use the actual approved method. The allowed input precision and numeric scale are controlled by that method; do not round a physical reading to obtain a passing value.
Enter the exact reading with a full stop. Supply the displayed unit exactly. A comma decimal, exponent, excess precision, forbidden negative or wrong unit can be refused as invalid input. There is no automatic unit conversion. An engineering input-range refusal is distinct from a valid measured value outside acceptance limits.
For an instrument-required check, select Reviewed instrument matching the actual instrument used. Its method, unit, range, validity and revocation state are checked. A typed serial or an old certificate date alone cannot satisfy the reviewed reference requirement.
Record all repetitions
Submit the current repetition and wait for its server outcome. Record each required repetition independently. Do not reuse a previous reading simply because the physical part or check is similar. A stale attempt or changed control requires refresh and review.
For pass/fail and choice checks, choose the observed answer rather than the answer expected to release the unit. An instruction acknowledgement confirms the stated task only when it was actually performed.
Keep valid failures
A valid value below or above the approved limit is retained as nonconforming and creates a finding. It is not an input error to erase. Continue recording required checks where the current state permits, then complete the inspection honestly. The unit remains held until the permitted supervised path resolves it.
A missing or malformed entry records no physical observation. Correct the input from the actual reading rather than repeating measurements without an authorised retest.
Correct the right kind of mistake
Use transcription corrections only for an inaccurately entered original reading. A new measurement after adjustment or further work belongs in an authorised full retest. Changing a recorded failure to a passing value is not a concession and never automatically releases the unit.
