Dust particle counter use, maintenance and cleaning procedures

Standard operation procedures for use, maintenance and cleaning of dust particle counter 1 Objective to establish standard operation procedures for use and maintenance of * dust particle counters, so as to standardize the operation process 2 Responsibility quality is responsible for the drafting of this document, and relevant personnel are responsible for the implementation of this procedure 3 Scope of application this standard is applicable to the use and maintenance of dust particle counter 4 content 4.1 ready state 4.1.1 power switch (33) in eject position 4.1.2 the sampling nozzle (34) and the self-cleaning port (38) are connected with hoses 4.1.3 connect the printer with the print interface (37) of the back panel with the print flat belt line; connect the 4.1.220v AC power supply to the socket (36) and connect the power supply 4.2 preheating 4.2.1 press the power switch (33) the power indicator (1) to light up the detection cycle for 1min the indicator (3) to light up, and the word "ready" appears on the multi-function display (2) 4.3 use 4.3.1 to press the measurement key (26), and the instrument will start * detection cycles At this time, the instrument indicator light (27) and range indicator light (25) are on, the air pump starts to work, the flowmeter indicates the flow, the multi-functional display screen shows that the original "ready" words disappear, and the particle number begins to display (if the original display time is still displayed, the particle number will not be displayed until the clock / particle size key (32) is pressed again) 4.4 (pull the sealing hose connector out of the sampling nozzle (34)) from the factory, connect the * end of the sampling pipe with (34), and connect the bell mouth (accessory) without the end, turn the flow adjusting knob (15), and adjust the upper end face of the float to the 2.83l/min marking position; then the instrument can start the test In order to prevent the dust particles adsorbed on the inner wall of the pipeline from affecting the measurement results, it is necessary to release * to the second measurement data measurement count, which can be divided into two types: total number and window 4.5 printing 4.5.1 when the measurement results need to be printed, press the print key (20) At this time, the print indicator light (8) indicates that after the end of the detection cycle, the measurement results can be automatically printed out The second print key (20) print indicator light (8) print command is released 5 Maintenance and repair 5.1 the working position of the instrument and the air inlet of the sampling pipe shall be under the same air pressure and temperature, so as to avoid affecting the operation of the air system and damaging the optical system by condensation II If it is necessary to work under the condition of pressure difference again, if the pressure difference does not exceed 200Pa and works under the condition of pressure difference and temperature, it will increase the measurement error and even damage the instrument 5.2 when handling the instrument, it should be handled with care and less vibration, which should be placed in a special box 5.3 conduct maintenance and inspection of the instrument * times a month, and fill in the maintenance record 6 Cleaning 6.1 after each use, wipe the surface of the equipment with a soft cloth to measure the dust, and dry it with a clean cloth 6.2 hang signs after cleaning the instrument, and fill in the use record of the instrument in time 6.3 the surface of the effect evaluation equipment shall be bright without stains Zhejiang Fuxia Medical Technology Co., Ltd., located in Daoxu Town, Shangyu District, Shaoxing City, Zhejiang Province, is a manufacturer in the purification equipment industry in East China According to iso14644-1 standard, GB50073-2001 national standard and GMP standard, we can provide professional air purification system engineering design, construction, testing and technical services for microelectronics, biomedicine, hospital operating room, optical fiber cable, food and beverage, precision instrument, semiconductor and new material application industries The company's main products are purification bench series, wind shower series, ventilation cabinet series, biosafety cabinet series, dust particle counter, planktonic bacteria sampler, which are widely used in medical and health, electronics, pharmacy, biology, food, agriculture and forestry, animal husbandry and veterinary, inspection and quarantine, aerospace, automobile manufacturing, precision instruments, universities and scientific research institutions Zhejiang Fuxia Medical Technology Co., Ltd is dedicated to serving the global consumers and distributors with our products, humanized services, low prices, and warmly welcome you to join us!
