1. Preheat in advance. Electronic kitchen weighing scales usually need to be preheated before use, and the preheating time for each scale is often different. In general, the higher the accuracy of the scale is, the longer the preheating time is. You can preheat the scale according to the instructions in the manual and extend the preheating time if necessary. As a matter of fact, many users use the scale as soon as it is turned on, which can not guarantee the performance of the scale. Therefore, the preheating of electronic kitchen weighing scales is related to the accuracy.
2. Environment conditions. Environment conditions are also an important factor affecting the measurement performance of electronic kitchen weighing scales. If there is no special temperature limit specified in the operating instructions, the electronic kitchen weighing scales should be used in -10℃ to 40℃ to ensure the normal working; if there is specified special temperature limit, the electronic kitchen weighing scales should work under the specified temperature condition. Electronic kitchen weighing scales also have requirements on the humidity of the environment. For example, Class I electronic kitchen weighing scales require more than 80% relative humidity.
3. Leveling condition. Common high-precision electronic kitchen weighing scales are equipped with leveling devices and levelers. We should check the leveling condition of the electronic kitchen weighing scale frequently in use. In fact, some users often neglect to check the leveling condition of the scales, which is also the main reason for inaccurate data.
4. Calibrate at any time. Some users believe that electronic kitchen weighing scales are accurate in the validity period after periodic verification, but often ignore the importance of calibration, or they even do not calibrate the scale. Due to environmental conditions change, human and other factors, the weighing performance of electronic kitchen weighing scales may change slightly in use, so daily calibration is required.
1. Cut off the power supply, unplug the power cord and clean the scale body. Wet and wring out a gauze, dip it in a little neutral cleaning solution, and clean the scale dial, display filter and other parts of the scale body with it.
2. If the electronic kitchen weighing scale is not used for a long time, the scale must be wiped up, and put into plastic bags with desiccants. You should take out the dry batteries. When using rechargeable batteries, charge them once every three months to ensure their service life.
3. Check the sensor periodically. Check whether the sensor is damp or oxidized, and whether there are foreign bodies and dust around the moving part. If any abnormality is found, it should be cleaned and maintained in time to prevent the inaccurate weighing caused by foreign matters and the jamming of the scale.
