How to use the graduated cup?
Hold the measuring cup so that it is naturally vertical, and keep the line of sight horizontal to the lowest point of the concave surface of the liquid in the Du measuring cup, and then read out the volume number of the liquid taken. Otherwise, the reading will be higher or lower.
Look up and down when reading:
When looking down, the line of sight is inclined downward, and the intersection point between the line of sight and the cylinder wall is on the water surface, so the data read is high, and the
Actual measured solution value is low.
Looking up is that the line of sight is inclined upward, and the intersection point between the line of sight and the cylinder wall is under the water surface, so the data read is low, and the actual measured solution value is high.
Reading time:
After the liquid is injected, wait for 1-2 minutes to make the liquid attached to the inner wall flow down, and then read the scale value. Otherwise, the reading value is too small.
