Korui Shiting shares Yingfukang with youExperience in using CDG series film gauges

One:

If for the first timeuseCDGIn the same chamber environment, it was found that the pressure display of the vacuum gauge was inconsistent when using a thin film vacuum gauge.pleaseconductbelowtroubleshoot：

1. Check whether the real-time pressure of the chamber meets the working pressure requirements of the vacuum gauge.

2. Check if the installation direction of the vacuum gauge complies with the manufacturer's specifications(The default installation at the factory is vertical, if changed to horizontal installation, recalibration is required).

3. Check the airtightness of the relevant air circuit and determine if there is any air leakage.

4. Check if there are corrosive gases in the chamber environment that may interfere with the normal operation of the equipment.

5. Check if there is really any inconsistency in the pressure inside the cavity.

6. Check if there is a malfunction in the vacuum gauge itself.

1、CDG series film gaugeBefore purchasing, special attention should be paid to its range. The maximum detection level of the vacuum gauge itself is full range downward4 orders of magnitude, it is recommended to detect pressure 2.5 orders of magnitude below full range. For example, for a thin film gauge with a full range of 1000Torr, it is recommended to use it within the range of 5-1000Torr.

2、CDG seriesWhen the film gauge leaves the factory, the vacuum gauge defaults to verticalupwardDirection calibration. The working principle of a thin film gauge is that pressure causes the membrane to deform, and the amount of deformation is proportional to the magnitude of the pressure. Due to the weight effect of the capacitor diaphragm itself, the installation direction of the vacuum gauge is different, and the deformation of the diaphragm itself will also change, ultimately leading to deviation in the pressure display results. So it's not verticalupwardInstallation requires recalibration of the vacuum gaugeafterReuse.
