Operating instructions of Laibao and Zhenghua vacuum gauges Model: oerlikon

1. The front of the vacuum gauge is a display panel to display the vacuum degree. The large four digit number on the left side displays the vacuum base A, and the small number on the upper right side is a multiple of the true degree displayed by A.

2. The first one in the upper right corner behind the vacuum gauge is the power switch, and the second one is the fuse. The third is the power socket. The first one on the left is the sensor seat. The second is the data transmission socket. The third is the reading switch.

Conversion method of reading method of vacuum gauge

1. First find the switches 1, 2, 3 and 4 at the bottom left behind the vacuum gauge;

2. When they are all OFF, the vacuum reading is millibar (mb);

3. When 1 is turned to ON, the vacuum reading is Pa;

4. When 2 is turned to ON and 1 is turned to OFF, the vacuum reading is Torr;

5. 3. 4 Always be in the OFF position;

6. Vacuum reading method: the initial setting is Pa. When the upper right corner is displayed as 0, the value A on the left is actually read, which is the vacuum degree at that time; When the upper right corner is displayed as 1, the left value A is left to 10, that is, the vacuum degree is A × 100Pa； When 2 is displayed, 100 is left, that is, the vacuum degree is A × 100Pa； By analogy, if the display is abnormal, please restart.
