A Brief Discussion on Common Sense for Using and Maintaining Asphalt Softening Point Apparatus
2020-03-25
The asphalt softening point tester is equipped with a high-precision imported temperature sensor, capable of measuring temperature and maintaining a heating rate of 5 ± 0.3℃ per minute—fully compliant with the 5 ± 0.5℃ specification stipulated in asphalt standards. The instrument features a large-screen LCD display, offering simple, clear, and user-friendly operation. General precautions for using the asphalt softening point tester:
1. Personnel using the equipment for the first time must operate under the guidance of experienced personnel and may only perform independent operations once they have become proficient.
2. When using the equipment, carefully read the technical manual, familiarize yourself with the technical specifications, operational performance, usage methods, and precautions, and strictly follow the step-by-step instructions provided in the instrument’s user manual.
3. Before powering on electronic instruments and equipment, ensure that the supply voltage matches the instrument’s specified input voltage. Instruments and equipment equipped with three-wire power plugs must be plugged into power outlets with protective grounding to ensure safety.
4. The instruments, equipment, and materials used in the experiment should be arranged reasonably and neatly, facilitating operation, observation, and data recording.
5. When using the device, its input signal or external load should be kept within the specified range; overloading is strictly prohibited.
6. The equipment should not be operated or used in magnetic or electric fields; shielding measures must be taken to prevent damage to the instruments and equipment or to avoid reduced measurement accuracy.
7. Optical and chemical instruments and their accessories should be handled with care to avoid vibrations. Never touch the surfaces of optical glass with your hands. If dust or dirt is found, do not wipe it off with your hands or a cloth; instead, use specialized cleaning products or tools designed specifically for this purpose.
8. Before using mechanical instruments and equipment, it is essential to run them under no-load conditions first to ensure they are free of malfunctions before loading them for actual use. Lubricate them before use and wipe them clean after use.
The asphalt softening point tester requires careful daily maintenance and upkeep:
1. Instruments and equipment must not be disassembled, modified, or taken apart for use at will. If it is indeed necessary to develop new functions or carry out renovations and upgrades, approval procedures must be followed in accordance with the hierarchical management authority before implementation.
2. Establish a regular verification and calibration system for key technical indicators of large-scale, high-precision, and valuable equipment to ensure that the equipment maintains its proper technical specifications. Keep accurate records of all usage activities.
3. Regularly maintain and service equipment, and store it in a dry, well-ventilated area. For instruments and equipment that will be left unused for extended periods, power them on periodically to prevent moisture and mold from damaging the equipment and its components.
