Read the following technical procedure:
To calibrate an optical refractometer before testing field samples, a technician begins by wiping the prism glass clean with a soft lint-free lens tissue. Next, two drops of distilled water are applied directly onto the prism face. The daylight plate is then closed gently over the prism to spread the liquid evenly without trapping air bubbles. Finally, while looking through the eyepiece toward a light source, the calibration screw is turned until the shadow line aligns exactly with the zero mark on the scale.
Match each stage of the calibration process with its corresponding mandatory action.
- First stageWiping the prism glass clean with a lint-free lens tissue
- Second stageApplying two drops of distilled water onto the prism face
- Third stageClosing the daylight plate gently over the prism
- Final stageTurning the calibration screw to align the shadow line with zero
Cevap
The first stage matches wiping the prism glass clean, the second stage matches applying two drops of distilled water, the third stage matches closing the daylight plate gently, and the final stage matches turning the calibration screw to align with the zero mark.
Each procedural stage matches the explicit chronological transitions in the passage: 'begins by' indicates wiping the prism glass first, 'Next' introduces applying distilled water second, 'then' signals closing the daylight plate third, and 'Finally' designates turning the calibration screw as the concluding action.
