（2） Installation

1. Avoid using in environments with strong vibrations and electromagnetic interference.

The equipment needs to have a good working ground wire (grounding resistance)<20~25 ohms);

The equipment casing is well grounded(Protecting ground wire)； 2→

2. capacitanceThin film vacuum gauge Should be installed in a vertical position (as shown in the figure)

When the device must be installed in a horizontal or other angular position

It is necessary to recalibrate the angle and correct the additional errors caused by it.Figure 1 PBS-510xx-C1typeThin film vacuum gauge

3. Vacuum connection standard configurationadoptNW16 ISO-KF(i.e. KF-16)Vacuum quick release flange, with supporting parts available

KF-16 welded flange made of 304 stainless steel material, along with clamps, center brackets, and O-ring rubber seals、Connect to equipment pipelines or containers by welding flange heads. Pay attention to checking the welding quality of the flange, the smoothness and cleanliness of the flange end face and sealing ring during installation, and ensure good vacuum sealing and stable and firm installation.

(IV)Measurement calibration

PBS-510xx-CThe Type 1 thin film vacuum gauge is a high-precision measuring instrument and should be regularly calibrated. The accuracy of the standard used for verification should be higher than the accuracy level of the instrument being verified by one levelaboveIf zero calibration is required during use, it must be donecompareA high vacuum source. It is recommended not to be casual in daily lifeon one's ownAdjustment, can be sent (with this project)CNASLocal administrative metrological technical institutions that verify qualifications for calibration and calibrationAnd calibration.The recommended calibration cycle is one year.

• After sales service and precautions

1.Before use, be sure to read the user manual carefully to prevent accidental operation;

2.If there is a malfunction, please contact the manufacturer in a timely manner and do not repair it without authorization to prevent human error.

3.The warranty period for the instrument is 18 months. If it exceeds the warranty period,Or intentionally damaged, or dismantled by oneself ，Need to pay for maintenance costs;

4.When connecting secondary instruments, it is necessary to have a detailed understanding of their technical performance, input impedance, and measurement resolution, which must comply with the specific technical specifications of the thin film vacuum gauge. It is recommended that the input impedance of the secondary instrument must be greater than100k~1000k ohms, measured ADtransformationThe resolution is higher than 20 bits；The external power supply voltage must meet the specific specifications of the thin film vacuum gauge, as detailed in the product technical specifications.
