2. Then press the "2" key, and 75000 will appear in the single column. You can ignore this step and press the "Add" button to enter the next step.
3. The weight column shows: d 1, and the single column shows: 2, indicating that the precision of this scale is 0.2g, and then press the "Add" button to enter the next step.
4. This is the time when the weight value will appear. This step is more important. For a weight of 5000g, you must enter 50000, because there is a 0 after the decimal point. If only 5000 is entered, only 5000 will be displayed after calibration, with no decimal point. After entering, press the "Add" button to enter the next step.
5. At this time, the weight column of the electronic scale will appear: LCP, and the single column will appear: OFF.
6. Then press the "Add" button to enter the next step. A code (Figure 2) appears, which can be ignored, and then press "Accumulate", as shown in the following figure:
7. Weight column appears: CAL, single column appears: 0, and weight value appears in total column. Prepare the weights, and then press the "Add" button to enter the next step.
8, put away the weight, wait for a few seconds after the electronic scale will automatically correct. When the weight of the weight bar jumps, it means that the correction is completed.

Calibration method of household electronic scales;
1. In the power-off state, press and hold the "Mode" key, and then press "On/Off". When a set of internal code values appear on the display screen, release these two keys, for example, "-7484" will be displayed. Pressing the "On/Off" key again will prompt you to enter the corresponding weight in grams. After putting the corresponding weight, the display will quickly show "Pass". It can be used normally after restarting.
2, if there is no weight, you can weigh the corresponding weight on the electronic scale, such as glass cups, add and subtract water appropriately, fine-tune for many times, or you can adjust a quasi-weight.
Maintenance and maintenance of electronic balance
1, put the balance on a stable workbench to avoid vibration, airflow and sunlight.
2. Before use, adjust the level to the middle position.
3, electronic balance should be preheated according to the requirements of the manual.
4. When weighing volatile and corrosive substances, put them in a closed container to avoid corrosion and damage to the electronic scale.
5. Self-calibration or regular external calibration of the electronic balance is often carried out to ensure that it is in the best state.
