Force gauge is a mechanical measuring instrument used for push and pull testing. The force gauge is suitable for push-pull load testing in industries such as electronic appliances, light industrial textiles, construction hardware, lighters and ignition devices, fire-fighting equipment, pen-making, lock-making, fishing gear, power machinery, scientific research institutions and so on. For example, it is used to test the breaking force of hair in the cosmetics industry, and is used to measure the strength of packaging materials such as tapes and films in the packaging industry.
 
Force gauge can be divided into push-pull dynamometers, tension meters, special tensile test frames, special tensile test machines, tensile testing machines, special tensile testers, etc. according to their functions, and according to the display mode, force gauge can be divided into analog force gauge and digital force gauge .
 
I. How to use analog force gauge
1. First of all, there are two types of analog force gauges: flat plate and cylinder, which are different in appearance. When making a selection, the range should be mainly based on the approximate measurement range required. Do not exceed the range, otherwise, it will easily damage the force gauge. It is not advisable to choose too wide range, so that it is not easy to observe the readings and the accuracy is low.
2. Secondly, when measuring, first check whether the pointer is at the zero position. If it is not, adjust it to the zero position. This is sometimes easy to overlook, so people often make measurement when the pointer is not at the zero position, which will result in the wrong measured values.
3. Thirdly, pay attention to the reading method during measurement. Keep your eyes flat on the pointer, and don't squint so as to minimize reading errors. There are two main types of dynamometer values, namely grams and Newtons. Be careful not to confuse them.
 
II. How to use digital force gauge
1. Check whether the battery voltage is normal before use. If the battery is under voltage, please charge it in time, otherwise there will be deviations in the measurement.
2. Estimate the size of the measurement and select a force gauge with an appropriate range. If the measurement exceeds the range, the force gauge sensor will be damaged.
3. When the measured value is less than 3% of the force gauge measurement range, the accuracy will deviate.
4. When not in use for a long time, the force gauge should be charged regularly.
5. When the weather is humid in summer, attention should be paid to the storage environment of the instrument to avoid corrosion and rust.
