Description

I. Overview • PDM-520 miniature (MINI) precision resistor (Pirani) vacuum meter is designed for online vacuum display and on-site vacuum testing. Using optimized advanced electronics technology and device surface mount technology, the structure is more compact and firm, ensuring accurate measurement and reliable quality of the instrument. It is currently the first leading vacuum measuring instrument in China. • This instrument is suitable for 5 × 10-2... The gas between 1.0 × 105PA is measured in vacuum. II. Technical data • Regulatory (vacuum sensor) :ZJ-52T universal resistance gauge • Measurement range: 5 × 10-2~1.0 × 105PA • Accuracy (nitrogen): ± 40% of 3 × 103~1 × 105 Pa reading ± 20% of 1 × 10-1~3.0 × 103PA reading ± 40% of 5 × 10-2~1 × 10-1Pa reading • Fixed Point Range: 5 × 10-1~3.0 × 103PA • Fixed point indicates that the vacuum reaches the fixed point value and the green light is on • Overall dimensions desktop: 70 × 55 × 70 (width × height × depth) shelving type: 90 × 60 × 70 • Weight 0.5Kg III. Usage environment • Vacuum measurement: 5 50°C • Storage:-5 to 80°C • Relative humidity: less than 80 LEDs IV. Power supply • Power adapter voltage range: DC DC12---24V/1A V. Usage • Connect the Resistance gauge to the vacuum vessel or pipeline under test by clamp or other methods. • Connect the power adapter to the vacuum meter power socket or the +1 pin and-2 pin of the D-sub 9 socket, connect the power supply, warm up vacuum meter and regulate, and make it at atmospheric pressure (ATM) run for at least 5 minutes. • If you do not need to set the panel, you can start air pump groups for vacuum detection. VI. Setting instructions Fixed point setting value Special note: operate within 5 seconds after the power supply is connected, and do not operate after 5 seconds. The instrument enters the measurement strong state. After that, the fixed-point value cannot be changed, and only the fixed-point value display can be called up. **Click Settings: ①** * the display value is flashing, ② Press settings to modify the value (0-9 cycle),③ click settings again, the second display value flickers,...... Repeat ① ② the operation to complete the decimal and index setting. After the setting of the last digit is completed, click settings to exit the setting. The instrument automatically remembers the above fixed-point value, and enter the measurement strong state to display the current vacuum value; Or restart the power supply to directly enter the measurement strong state. ﹡ Atmospheric Calibration: in the atmosphere, connect the power supply, preheat vacuum meter and regulate, and press "set number" Jian and "zero · full" Jian for 2 seconds to lift and release, the instrument automatically adjusts the atmospheric reference value, showing 1.0E 5. (If the display value deviates slightly from 1.0E 5 under strong atmosphere, calibration is not required.) // Zero calibration: (the zero point has been calibrated with the distribution regulation when the vacuum meter leaves the factory, only when it is used for a period of time or the new regulation has been replaced) connect the regulation to the vacuum system where the vacuum can be obtained higher than 1 × 10-2PA, vacuum pump to 5 × 10-2PA, and press "set number" health and "Zero • Full degree" Health: instrument zero display value reduction, at the same time, press "set number" Jian and "set" Jian: instrument zero the display value increases, so that the zero display value is 5 × 10-2Pa. Note: When the display value of the instrument is less than 1 × 102, the display value can be modified to a known vacuum value through the above operations.
