2. some laboratory instruments are not suitable for operation and use in the magnetic field or electric field. Shielding measures must be taken to prevent the instrument and equipment from damaging or reducing the measurement accuracy.
3. mechanical equipment, before use must carry out unloaded operation to ensure that no fault can be used after loading. For lubrication, after use wipe clean, pay attention to the daily maintenance and maintenance.
4. instruments and equipment are not allowed to be disassembled or altered at any time. It is necessary to develop new functions or update them.
