First, you must choose the dynamometer correctly. The dynamometer refers to a mechanical force gauge and a digital dynamometer.
Mechanical dynamometer should pay attention to the problem:
Mechanical dynamometers are primarily considered for their range when selected. There are various types of dynamometers such as 10N, 20N, 30N, 500N, etc., according to the approximate range measured, do not exceed the range, which is easy to damage the dynamometer. It is also not advisable to choose too large, so that it is difficult to observe the reading and the accuracy is low.
Secondly, when measuring, first observe whether the pointer is at the zero position, and if it is not at the zero position, adjust to the zero position. This is easy to ignore when doing experiments, often measuring a pass, the pointer is not at the zero position, the measured values ​​are wrong.
The third is to pay attention to the reading when measuring. Eyes should look flat on the pointer, do not squint, and minimize reading errors. There are two main types of dynamometers, namely, grams and Newtons. Be careful not to confuse them.
Digital dynamometer should pay attention to the problem:
1. Please check whether the battery voltage is normal before use. If it is under voltage, it should be charged in time, otherwise the measurement will be biased.
2. Estimate the measurement size, select the dynamometer of the appropriate range, and measure the out-of-range, which will cause damage to the dynamometer sensor.
3. When the measured value is less than 3% of the force measurement range, the accuracy will vary.
4. When not in use for a long time, the dynamometer should be charged regularly.
At the same time, when the weather is wet in summer, the instrument should be kept in an environment to avoid rust.
Problems to be aware of when using a Souter dynamometer
The dynamometer is a commonly used instrument in factories and laboratories. We often use it to measure gravity or tension in experiments. So how do you use a dynamometer?
