2011-9-16 15:27:59

不要 在端子之间或 端子和地 之间施加超过 校验仪 上标示的额定电压。 1. Do not apply more than the rated voltage marked on the calibrator between the terminals or between the terminal and the ground . Vdc The maximum voltage between the terminals is 30 Vdc ;
使用前校验仪 ,先测量一下已知电压以确认工作正常 2. Before using the calibrator , measure the known voltage to confirm that it is working properly ;
使用前应确定电池电量 是不是 充足, 如果 电量过低应 充电后使用 3. Before use , make sure the battery is sufficient. If the battery is too low , you should use it after charging .
校验仪 采用锂电池供电,根据锂电池充放电特点管理电源,以延长电池的使用寿命 4. The calibrator is powered by a lithium battery, and the power is managed according to the characteristics of the lithium battery charge and discharge to extend the battery life ;
不要 使用已损坏的 校验仪 5. Do not use the damaged calibrator . 的外壳 是不是 有断裂或 缺少塑料元件 6 特别要注意接头周围 是不是 绝缘 Before use, check the housing of the calibrator for cracks or missing plastic components . 6. Pay particular attention to whether the joints are insulated around them .  
根据测量要求选择正确的功能和量程档 7. Select the correct function and range according to the measurement requirements ;
使用探头时,手指不要碰到探头的金属触点。 8. When using the probe, do not touch the metal contacts of the probe with your fingers. Keep fingers behind the finger guard of the probe ;
当测试线的一端被插入电流插孔的时候, 不要将 另一端的探头碰触电压源 9. When one end of the test lead is plugged into the current jack, do not touch the probe at the other end to the voltage source ;
检查测试线 是不是 有损坏或 暴露的金属。 10. Check if the test leads are damaged or exposed metal. 损坏,使用前应把损坏的测试线更换。 If damaged, replace damaged test leads before use. 是不是 导通 Check if the test leads are conducting ;  
遵循所有设备的安全步骤进行操作。 11. Follow the safety procedures for all equipment.
