Letters
Letters left after the figures went out
These are not scores. They are remarks from people who sent a log and got pages back. One of them names a delay; we left that in. If you want to see how a page looks before you write, the chart cabinet holds anonymised specimens.
They caught that our night probe was an hour behind the day book. The charts looked wrong until that note went on the figure. After that the written reading matched what the night shift already felt in the house.
I wanted six clean figures for a works meeting and nothing else. They still asked about units twice. Slightly slow, but the axes were labelled as the electrician had recorded them, not as someone guessed.
The walkthrough was awkward because our logger sits behind a hot cabinet and Giorgi would not pretend he had seen the tag. He wrote that the tag was unreadable. That sentence saved us from drawing a month of mixed channels.
Standing notes are dry reading, which is what I asked for. One month they flagged a night that never dropped. It was a stuck vent, not a probe fault. I wish the note had arrived before the Monday meeting; it came on Tuesday.
Tamar sent the draft with our bay names spelled as we spell them in the book. Small thing. The vibration figures still needed a second pass because I had forgotten to say which motor was overhauled in May.
The dryer that disagreed with itself
A mill on the edge of Kutaisi, late winter
Two pens sat on the same dryer: one on the inlet air, one on the product. For weeks the night book claimed the inlet was cooler than the product, which the day crew said was impossible. The files were sent as two exports with different logger clocks.
The drawing showed the inlet series running fifty minutes behind the product series after a power cut. Once that lag was marked, the night 'impossibility' became an ordinary sequence. The written reading did not blame a person; it asked that both loggers be set from the same clock after outages.
The briefing was twenty minutes longer than planned because the electrician brought a third strip from a spare probe. That strip was not in the commission. We logged it as a question for a later chart set rather than squeezing it onto the pages already promised.
Ridge vents and a Friday irrigation
Glasshouse west of the Rioni, summer
The keeper wanted to know whether opening the ridge at noon was doing any work, or whether the irrigation on Friday afternoons was the only reason the crop stopped wilting. Soil moisture and ridge temperature arrived as one file with a fifteen-minute interval and two missing Sundays.
Figures were drawn with irrigation hours as margin marks, not as a smoothed average. The reading said the ridge opening dropped the peak by a small amount on dry days and almost not at all on the Fridays when the lines ran. That was less flattering to the vents than the keeper hoped, and she said so. The pages still went to the owner with her note attached.
