Its our

6、 start point and purpose to get your trust. We will provide technical support and after-sales services to you for you to use this product safely and conveniently.1. Product has been tested strictly before dispatching from the factory. Normally no need to do any adjustment if there is no severe damag

7、e after open the box. Please configure the parameter according to your requirements.2. Please install it correctly on the instrument and fix it.3. The panel of the product is soft touch type, please touch it gently by your finger and dont press it with hard material.4. Please dont scuff or collide t

8、he display part of the meter.5. As the special requirement of customer and unceasing perfect needs of software as well as the function has increased, the software is always being upgraded and changed. So every software and user manual has the edition number. There is the edition explanation on the c

9、over of the user manual. Please pay attention that the edition of user manual should be identical with that of the software.1.2 Summary of the product2002 industrial online acidometers is one of the 2000 series water quality analyzer, and is a measuring control instrument with integration of online

10、continuous monitoring, adjustment and control functions. It can be used in combination with various PH measuring pool manufactured by our company to meet various kinds of requirements in different applications. Along with pure water and super pure water electrode, it is applicable in measuring and c

11、ontrolling of PH value in water with the electricity conduct ratio less than 10S/cm, such as chemical makeup water at the electric station, saturated water and condensed water etc.2002 industrial online acidometers is a multi-function instrument with fully new concept, integrated with pH measuring,

12、adjustor, temperature measuring and compensation, alarm controller, advanced algorithm and loop control, suitable for various applications. Chinese interface-total Chinese liquid crystal multi-parameter displayed simultaneously, menu reminder, easy for operation and friendly human-machine interface.

13、 Convenient operation-simple and direct human-machine interface to make user rapidly master the operation and running of the instrument. High intelligent-adapts single chip micro processing technology to minimize the size and improve the reliability and anti-interference ability. Perform reliability

14、-integrated with multi anti-interference, preamplification with high impedance, precise and reliable measuring and running. Multi and practical function -multiple functions and outputs to drive all kinds of executive mechanism, forming a good controlling system. Communication function-standard light

15、 and electricity isolation RS485 communication interface to be conveniently linked with printer, data trans-memory or linked with computer to form the distributed control system.1.3 Functional FeaturesAdapts international standards and modular design. DIN144X144 international standard shell, 180mm i

16、n longwise to minimize the space between the control boxes. Total Chinese liquid crystal multi-parameter displayed simultaneously, menu reminder, easy for operation and friendly human-machine interface. Four digital soft touch type water protecting keyboard with key function reminder to make the ope

17、ration very simple without special training.Liquid crystal screen with a heliotropism to guarantee the use in poor light.Calibration method: standard buffer solution can auto identify 2 digital fixing standard, and display the latest calibrated data and date; adapts digital calibrating system and au

18、to correction technology to achieve precise calibration and eliminate the error aroused by temperature drift and time drift. Auto temperature compensation between 0-95, also can be set as compensation by manual to meet different requirements.Access code is set in calibration and programming to preve

19、nt the operation of non-related personnel.Optical isolated 2 circuit analog DC 4-20mA output, user programming corresponding to pH Optical isolated 4-circuit relay switching value output, user program sets the relay working status.Optical isolated RS-485 communication interface, can be linked with t

20、he equipment such as printer, data trans-memory etc and also can be connected with a group of instruments to form a net, and linked with computer to realize long distance communication for centralized administration.Adopt WATCHDOG circuit, software trap, power-fail protection and digital filtering t

21、echnology etc., attach importance to endure error capacitance to achieve strong anti-interference. Sensor input/micro process chip/ power/ isolated between each output module can effectively restrain various interferences in industrial sites.1.4 Application rangeIt is designed to meet the large requ

22、irements from industrial usage, including drinking water, sewage water, industrial constant control and monitor (chemical, petrifaction, to make paper by paper pulp, refine sugar, food and beverage, surface processing and iron steel industrial) and measure pure water and super pure water (steam gene
