3, before and after the use of a variety of measuring instruments must be routinely inspected and calibrated, the use of the process of good maintenance, timely maintenance after use.
4, a variety of photoelectricity, laser instruments must be regularly sent to qualified departments for identification. Identification time should not exceed the specified time to ensure the accuracy and precision of measurement.
5, it is strictly prohibited to use the instrument without inspection and identification, correction of the factory precision, more than the identification cycle, as well as missing parts and display value is difficult to defend.
6, the use of total station, photoelectric rangefinder, in the absence of a filter prohibit the telescope directly to the sun, so as not to harm the eyes and damage to the distance measuring part of the light-emitting diode.
7, in strong sunlight, rain or humid environment, be sure to work under the cover of an umbrella.
8, the instrument should be carefully and gently put to avoid strong impact vibration, the placement of the instrument should be checked before the firmness of the tripod, the entire process of operation staff shall not leave the instrument to prevent accidents.
9, transfer station, even if very close should be removed from the instrument box. After the measurement work is finished, turn off the machine and remove the battery before packing, and provide suitable shock absorption measures for long-distance transportation to prevent the instrument from sudden vibration.
10. Measuring instruments should be stored in a special warehouse in a dry, ventilated, shock-proof, fog-proof, dust-proof and rust-proof environment. Instruments should be kept dry, in case of rain, wipe it dry, put it in a ventilated place, dry and then boxed. All kinds of instruments should not be subject to pressure, freezing, moisture or high temperature, the instrument box should not be close to the stove or heating pipe.
11, the instrument long-distance transportation, should do a good job of shockproof, moisture-proof work. When loading must make sure that the instrument is placed, not upside down. Measuring personnel to carry the instrument in the car, the instrument should be placed on the shock pad or leg hold, in order to prevent damage to the instrument vibration bumps.
12, must establish and improve the measuring instruments and equipment ledger, precision measuring instruments card, instrument files and other systems, instruments out of storage, storage and relocation of the project, should be registered, signed procedures.
13, the management of measuring instruments, by the company's precision measuring team to develop inspection and evaluation methods, the maintenance of instruments with remarkable achievements in units and individuals to reward, due to improper use, poor storage caused by damage to the instrument should be held accountable in a timely manner, according to the circumstances of the punishment.
14, when the measuring instruments, tools for the following conditions are unqualified: has been damaged; overload or misoperation; the function of the suspicious; display is not normal; more than the required weekly inspection to confirm the time interval; the integrity of the instrument gag has been destroyed; photoelectricity, laser instruments more than the service life of the zero drift is serious, unstable measurement results, measurement results of the reliability of the low, you must apply for the scrap! When the routine instruments are damaged beyond repair, or when the instruments are worn out, difficult to recognize the value, unstable performance, affecting the quality of measurement, they must be applied for scrapping.
15, the application for the purchase of measuring instruments and scrapping by the project department reported to the company's engineering management department, the company's chief engineer and the competent leader is responsible for the approval of the company's precision team of the project's instrumentation and management of semi-annual inspections, the requirements of the accounts, objects, cards in line with the technical file is complete.
