What a lighting survey report should contain

The result, against each figure

This is the first page of the specimen. Every value on it is invented, and the result is mixed on purpose, because a mixed result is what real surveys usually produce.

1. Each figure, with the measured value beside it. Uniformity came in at U_o 0.29 against 0.40 required, which is below. The average came in at 222.6 lux against 200.0 lux, which is at or above. A reader gets both numbers as well as the outcome.
2. What it was judged against. The line under the title names the requirement: a client requirement for the warehouse floor, entered by hand.
3. The number of readings, and the spread. 36 readings, from 64.9 to 273.5 lux. The readings tile also says the calibration was in date.
4. The measurement plane. "Horizontal, at floor level." Without this, nobody can compare the readings with anything.
5. When. The survey date, the time of the first and last reading, and when the report was produced, all in local time with the zone named (BST here).

Where the figure came from, and why it matters

Here is a requirement the survey came in below, as the specimen prints it.

1. What was required, and what was measured. The measured line gives the minimum, average and maximum behind the uniformity figure, so a reader can check the arithmetic.
2. The comparison, in plain words. "The lowest reading is further below the average than the requirement allows."
3. The source of the figure. "Client brief rev B", entered by the surveyor, who said which document it came from. If a reader has a different revision, they can see that at once.
4. No pass or fail. The report says the result was below the figure and stops there. Whether that matters is for the reader to decide.

The instrument, and how the readings got in

◆ Specimen data

A real screen from the app, on specimen data. It is what the surveyor sees before signing, and it holds the facts the report prints about the instrument and the grid.

1. The instrument. Make, model, serial number and calibration certificate. On the specimen the serial and certificate read SPECIMEN, because they are invented.
2. How the values got in. Here they were typed from the meter's display, and the record says so. If a survey mixes typed readings with readings that came over Bluetooth, the report says which were which.
3. How the grid was set, and what was assumed. The method, the number of points and the spacing. It also says the mounting height was assumed rather than measured.
4. Every reading, with its time. Points that were planned but not measured are counted, not dropped.

Where each reading was taken

1. Each reading at its point. Every value is labelled where it was taken, so a dark corner shows up as a place on the plan.
2. The minimum and maximum, ringed and named. They are named in words as well as coloured, so colour is never the only signal.
3. The plan's own caveats. The note under the plot says that no drawing was imported, that the outline is the surveyed extent and not a scaled drawing, and that the point count rests on an assumed mounting height.
