strip chart การใช้

• Readings were typically recorded on circle charts or strip charts.
• The first commercial devices ( medical strip chart recorders ) were introduced in 1951 by Siemens.
• Strip chart recorders have a long strip of paper that is ejected out of the recorder.
• Chart recorders may record several inputs using different color pens and may record onto strip charts or circular charts.
• Strip chart recorders with galvanometer driven pens may have a full scale frequency response of 100 Hz and several centimeters of deflection.
• Turning on bit 3 allowed strip charts to be used, while bit 4 turned it on for both graphs, the dual strip feature.
• In analog strip chart recorders such as used in electrocardiographs, electroencephalographs and polygraphs, galvanometer mechanisms were used to position the " pen ".
• Roll chart recorders are similar to strip chart recorders except that the recorded data is stored on a round roll, and the unit is usually fully enclosed.
• In the case of the Temperature Module, for instance, the system could display a thermometer showing the instantaneous temperature, or a strip chart continually recording the temperature over time.
• Mud logging ( or Wellsite Geology ) is a well logging process in which drilling mud and drill bit cuttings from the formation are evaluated during drilling and their properties recorded on a strip chart as a visual analytical tool and stratigraphic cross sectional representation of the well.
• GFAA spectrometry instruments have the following basic features : 1 . a source of light ( lamp ) that emits resonance line radiation; 2 . an atomization chamber ( graphite tube ) in which the sample is vaporized; 3 . a monochromator for selecting only one of the characteristic wavelengths ( visible or ultraviolet ) of the element of interest; 4 . a detector, generally a photomultiplier tube ( light detectors that are useful in low-intensity applications ), that measures the amount of absorption; 5 . a signal processor-computer system ( strip chart recorder, digital display, meter, or printer ).
