Under normal circumstances, instrument calibration should meet the following basic requirements: 1) Environmental conditions: If calibration is performed in a verification (calibration) room, the environmental conditions should meet the temperature, humidity and other requirements of the laboratory. If the calibration is carried out on site, the environmental conditions shall be based on the conditions that can meet the field use of the instrument. 2) Instrument: As a standard instrument for calibration, the error limit should be 1/3 ~ 1/10 of the error limit of the meter being calibrated. 3) Personnel: Although the calibration is different from the verification, the person performing the calibration should also be subject to effective assessment and obtain the corresponding certificate of qualification. Only the certificate holder can issue the calibration certificate and calibration report, and only such certificate and report Think it is effective. The calibration and verification of the instrument are similar: Calibration and verification are two different concepts, but there is a close relationship between the two. Calibration is generally compared with the measuring instruments with higher accuracy than the calibration gauges (called standard instruments) and the calibration instruments to determine the indication error of the calibration instruments, sometimes including some measurement performance, but often carried out Calibrated measuring instruments only need to determine the indication error. If the calibration is the verification content of the indication error in the verification work, it can be said to be a part of the verification work, but the calibration cannot be regarded as a verification, and the requirements of the calibration are not as good The verification is so strict that the calibration can be carried out at the production site, and the verification must be carried out in the verification room. Some people understand calibration as the process of adjusting the measuring instruments to the specified error range, which is not accurate enough. Although it can be adjusted during calibration, adjustment is not equal to calibration Agv Automated Guided Vehicle,Automated Transport Vehicles,Automated Pallet Forklifts ,Automated Guided Vehicle Changchun Rochiev Intelligent Equipment Manufacturing Co., Ltd. , https://www.rochiev-en.com
