1. Before using the instrument, first check whether the battery voltage is normal. If it is under voltage, please charge it in time, otherwise the measurement may deviate.

2. Do not use a push-pull force gauge during charging to avoid inaccurate measurement accuracy of the instrument

3. Estimate the size of the object being measured, choose a suitable instrument with a close range. If the measurement exceeds the range, it will cause damage to the sensor.

4. When the measured value is below 3% of the range of the dynamometer, there will be a deviation in accuracy.

5. Do not loosen the screws that secure the test head, as this will reduce resolution.

6. When not in use, the zero knob should be used to place the instrument display in the "0000" position, and the power should be turned off.

7. At the same time, when the weather is humid in summer, attention should be paid to the storage environment of the instrument to avoid rusting.

8. In case of unexpected crash. Press the reset switch with a hard object to shut down, and a reset button is arranged on the side of the push-pull force gauge.

9. Do not throw, drop, or collide with this instrument, or use it roughly and carelessly, as it is a precision measuring instrument that may be damaged.
