简介
校验仪出厂前经过全面测试并出具校验证书，建议每隔12个月重新校验一次。实际再校准的周期取决于
用户的特殊应用要求以及总的测量不确定度。
校准这些精密测量校验仪需要一等以上的活塞式压力计并由有经验的专业人员在可控环境条件下进行。
合格的校准人员应该具有必须的技术知识，文档，测试设备和工具并按照校准过程完成校准。
当检测仪器的精度时，发现超出规定指标值，就需要进行校准，补偿误差。
制造厂提供全面的、需要时可提供经N BT认可的校准服务。
基本过程
以下为校准过程中的一些指导要点,
一定
请使用高质量的线性和重复性好的压力源，在开始校验时， 须稳定一段时间(至 少1小时)。
请在温度适宜、湿度受控制的环境下进行校验,推荐的温度为21C土2°C。
使用活塞式压力计时要小心仔细，避免气流。
校准保护
为了保护意外损失，本校验仪的再校准由密码保护。出厂时密码设置为4321。建议用户自己尽快改变密码。
(参考5-3页的说明)
校准检查
将校验仪的读数和标准器的读数进行比较。标准器和校验仪之间的任何偏差都应该记录下来并进行比较。
如果偏差超出了允许误差的范围，或超出了其他的性能要求，则必须对仪器进行校准调整。
建议测量点选择为满量程的0%、20%、 40%、 60% 和80%、100%， 并运行上行程和下行程。参考表5-1到
表5--4，页5-15到页5-16中的关于测试输入值和允差的详细内容。
校准调整
如果校验仪工作正常，一般仅需要进行零点和满量程的校准。其他的非线性或温度影响造成的误差则需要
将仪器返回授权的服务机构或咨询厂家办事处进行调整。

brief introduction

The calibrator has been fully tested before leaving the factory and issued a calibration certificate. It is recommended to calibrate it again every 12 months. The actual recalibration period depends on

Special application requirements of users and total measurement uncertainty.

The calibration of these precision measuring calibrators requires more than first-class piston pressure gauges, which are carried out by experienced professionals under controllable environmental conditions.

Qualified calibration personnel should have the necessary technical knowledge, documents, test equipment and tools, and complete the calibration according to the calibration process.

When the accuracy of the instrument is detected and it is found that it exceeds the specified index value, it needs to be calibrated to compensate the error.

The manufacturer provides comprehensive calibration services approved by NBT when necessary.

Basic process

The following are some guiding points in the calibration process,

certain

Please use a high-quality pressure source with good linearity and repeatability. It must be stable for a period of time (at least 1 hour) at the beginning of calibration.

Please check in an environment with appropriate temperature and controlled humidity. The recommended temperature is 21C and 2 ° C.

Be careful when using piston pressure gauge to avoid air flow.

Calibration protection

In order to protect accidental loss, the recalibration of the calibrator is protected by password. The factory password is set to 4321. Users are advised to change their passwords as soon as possible.

(refer to the description on page 5-3)

Calibration check

Compare the readings of the calibrator with the readings of the calibrator. Any deviation between the standard and the calibrator should be recorded and compared.

If the deviation exceeds the allowable error range or other performance requirements, the instrument must be calibrated and adjusted.

It is recommended to select the measuring points as 0%, 20%, 40%, 60%, 80% and 100% of the full scale, and run the up stroke and down stroke. Refer to tables 5-1 to

Table 5-4, page 5-15 to page 5-16 for details of test input values and tolerances.

Calibration adjustment

If the calibrator works normally, it is generally only necessary to calibrate the zero point and full range. Other errors caused by nonlinearity or temperature effects are required

Return the instrument to the authorized service organization or consult the manufacturer's office for adjustment.
