The determination of the scale of the measured parameter of the recording paper should refer to ZBY123 "General Regulations for the Scale of Industrial Automation Instruments". The distance between two adjacent time scale lines of the long chart recording paper is 10mm for all kinds of feed speed recording papers. The minimum division value between two adjacent time scale lines of the circular chart recording paper is 15min. There are three scale lines A, B and C on the recording paper (which should correspond to the long scale line, medium scale line and short scale line of ZBY123 respectively). The width of the two groups of scale lines is shown in Table 3.

Technical requirements
4.1 Paper quality
QB/T3509—1999
The instrument recording paper should meet the requirements of relevant standards. 4.2 Quantitative
Long chart recording paper uses 40, 45 or 52g/m2 paper, circular chart thermal recording paper uses 80g/m2 paper, and circular chart ink recording paper uses 100g/m2 paper.
4.3 Smearing performance
When the recording pen draws lines on the recording paper and makes the recording paper "completely colored", the recording paper should not be damaged and the ink should not penetrate onto the recording paper platen

4.5 Appearance
4.5.1 The recording paper should be flat, without folds, wrinkles, incompleteness, holes, transparent spots, cracks and other paper defects that affect the use. The surface coating of thermal recording paper should be evenly hooked.
4.5.2 The guide hole should be smooth and there should be no obvious burrs or deformation. 4.5.3 The printed part of the recording paper should be correct and clear, the ink color should be consistent, and there should be no color spots or broken lines that affect the reading. 4.5.4 The tooth penetration at the folding part of the folding recording paper should be good, and it should not affect the continuous recording and paper collection. The end face of the folding book should be neat. Roll recording paper should be rolled on a dry and hard core tube. The core tube should not extend beyond the end of the roll. The end of the roll should be flat and clean. 4.5.5 Marking of the start and end
The folded start end should be cut at an angle of about 35° from the center of 30mm to both sides, and the roll start end should be cut at an angle of about 35° from the center line to both sides. When the long recording paper is close to the end, a conspicuous warning sign that the recording paper is about to run out should be marked on the horizontal start or end scale line. 5 Test method
