In the fields of industrial production and quality control, fully automatic pressure calibration devices play a crucial role. They can accurately calibrate various pressure instruments to ensure the accuracy of their measurement results. The fully automatic pressure calibration related devices produced by Huai'an Feichuang Instrument Technology Co., Ltd. (such as pressure gauges and other calibration equipment with high-precision pressure calibration functions) have received widespread attention due to their excellent performance. The following is a guide for using this type of fully automatic pressure calibration device.

preliminary preparation

Before using the fully automatic pressure calibration device, it is necessary to make sufficient preparations. Firstly, carefully inspect the appearance of the device to ensure that there is no damage, collision, or other issues, and that all connecting components are tight and not loose. Secondly, according to the range and accuracy requirements of the verified pressure instrument, select a suitable calibration medium, such as gas or liquid, and ensure that the medium is pure and free of impurities to avoid affecting the calibration results. At the same time, prepare necessary tools such as wrenches, screwdrivers, etc. for debugging and connection when needed.

Device connection

The key step is to correctly connect the fully automatic pressure calibration device with the calibrated pressure instrument. Select appropriate connecting fittings and joints according to the interface type of the device and instrument, ensuring a secure connection and good sealing to prevent leakage during the calibration process. After the connection is completed, check the connection part again to confirm that there is no looseness or leakage (liquid).

Parameter Settings

Turn on the power of the fully automatic pressure calibration device and enter the operation interface. According to the specific parameters of the verified pressure instrument, such as range, accuracy level, etc., set corresponding calibration parameters on the device, including calibration pressure point, pressure rise and fall rate, holding time, etc. During the setup process, it is important to ensure that the parameters are accurate to avoid affecting the accuracy of the verification results.

Start verification

After completing the parameter settings, start the verification program. The device will automatically increase or decrease pressure according to the set parameters, and maintain the specified time at each calibration pressure point, while recording the displayed value of the calibrated pressure instrument. During the verification process, it is necessary to closely observe the operating status of the devices and instruments. If any abnormal situations are found, such as excessive pressure fluctuations or unstable instrument displays, the verification should be stopped immediately and the cause of the malfunction should be investigated.

Result analysis and processing

After the verification is completed, the device will automatically generate a verification report, displaying the error values of the verified pressure instrument at each verification point. Based on the report results, determine whether the instrument is qualified. If the instrument error exceeds the allowable range, it needs to be adjusted or repaired until it passes the verification.

post-maintenance

After the verification work is completed, residual media on the device and connecting components should be cleaned in a timely manner to keep the device clean. At the same time, regularly maintain and upkeep the device to ensure its stable and reliable performance.
