簡介
校驗儀出廠前經(jīng)過全面測試并出具校驗證書，建議每隔12個月重新校驗一次。實際再校準的周期取決于
用戶的特殊應(yīng)用要求以及總的測量不確定度。
校準這些精密測量校驗儀需要一等以上的活塞式壓力計并由有經(jīng)驗的專業(yè)人員在可控環(huán)境條件下進行。
合格的校準人員應(yīng)該具有必須的技術(shù)知識，文檔，測試設(shè)備和工具并按照校準過程完成校準。
當檢測儀器的精度時，發(fā)現(xiàn)超出規(guī)定指標值，就需要進行校準，補償誤差。
制造廠提供全面的、需要時可提供經(jīng)N BT認可的校準服務(wù)。
基本過程
以下為校準過程中的一些指導(dǎo)要點,
一定
請使用高質(zhì)量的線性和重復(fù)性好的壓力源，在開始校驗時， 須穩(wěn)定一段時間(至 少1小時)。
請在溫度適宜、濕度受控制的環(huán)境下進行校驗,推薦的溫度為21C土2°C。
使用活塞式壓力計時要小心仔細，避免氣流。
校準保護
為了保護意外損失，本校驗儀的再校準由密碼保護。出廠時密碼設(shè)置為4321。建議用戶自己盡快改變密碼。
(參考5-3頁的說明)
校準檢查
將校驗儀的讀數(shù)和標準器的讀數(shù)進行比較。標準器和校驗儀之間的任何偏差都應(yīng)該記錄下來并進行比較。
如果偏差超出了允許誤差的范圍，或超出了其他的性能要求，則必須對儀器進行校準調(diào)整。
建議測量點選擇為滿量程的0%、20%、 40%、 60% 和80%、100%， 并運行上行程和下行程。參考表5-1到
表5--4，頁5-15到頁5-16中的關(guān)于測試輸入值和允差的詳細內(nèi)容。
校準調(diào)整
如果校驗儀工作正常，一般僅需要進行零點和滿量程的校準。其他的非線性或溫度影響造成的誤差則需要
將儀器返回授權(quán)的服務(wù)機構(gòu)或咨詢廠家辦事處進行調(diào)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.
