Operation and use of hand-painted 4 cups

Abstract: 手提涂4杯的使用方法包括：首先检查提梁连接是否稳固并能顺畅转动；用纱布或脱脂棉和样品溶剂清洁杯内，特别是流出口。将仪器放入测试液体中，迅速提起容杯并开始计时，当液体出现第一滴时停止计时，此时间即为液体的条件粘度。对同一液体进行三次测定，计算其平均值，且测定之间的差异不应超过平均值的3%。最后，使用后要彻底清洗和擦拭干净，以备保存。

How to use 4 cups

1. Before the test, first check whether the connection of the lifting beam is reliable and whether it can rotate freely.

2. Wipe the inside of the 4-cup hand-painted cup with gauze or absorbent cotton with the solvent used in the sample, especially the outlet part, and observe it with light until it is wiped clean.

3. Intrude the instrument into the liquid to be tested, lift the lifting beam with one finger and quickly lift the upper plane of the container cup away from the liquid surface, and at the same time start the stopwatch for timing. When the first drop appears in the middle of the sample wire, stop the stopwatch. The time is the full settling time of the measured liquid, that is, the conditional viscosity of the measured liquid.

4. For the conditional viscosity value of the same liquid, the arithmetic mean value should be calculated after three times, but the difference between each measurement should not be greater than 3% of the mean value.

5. After use, the viscometer should be cleaned and wiped clean for storage.
