The VR-18 Paperless Chart Recorder can be connected to a PC with an Ethernet cable allowing students to use the Brainchild's FREE software, allowing for streaming live data or downloading the data to an Excel spreadsheet to further manipulate the information for reports and assignments. Teachers can set up the display to a projector, allowing an entire class to view the data representations, and students can print the data collected from any of the display formats. After the experiment is completed, the class can view statistics from the recorded data including instant, average, min and max values. Educators and students working in laboratories and classrooms in universities across the country often use older paper chart recorder technology to record their live data onto hard copy. CAS DataLoggers together with high-quality manufacturer Brainchild has the solution with the VR-18 Paperless Chart Recorder, a high resolution (true VGA, 640x480 pixels) 18-channel data logger featuring an infrared detector, plug & play I/O card, high flexibility, and user-friendly operation, all in a compact size. Paperless chart recording is a much more user-friendly solution with an interactive dialogue simplifying both setup and operation procedures. This high performance and high connectivity equipment also offered personnel easy configuration and operation to get the project underway as quickly as possible.

The only possible reference is the reading of the displayed value, for example, of the current. Choosing an analog instrument ensures good reading stability, due to the mechanical inertia of the needle and the fact that the reader immediately knows whether the instrument is operating normally or if the reading is out of range. Connecting analog instruments is very simple; you just need to connect the phase and neutral cables to the instrument. Two auxiliary power cables should always be connected for digital instruments. In order to ensure that the instrument is properly protected, fuses must always be fitted to the power cables of the digital instruments and to the measurement inputs of the voltmeter. In multifunction instruments, not only the cables connected to the measurement, but also the RS485 serial port and the analog and digital inputs and outputs must be wired. If there is a large potential difference between neutral and earth, this could negatively affect the measurement, in the case of instruments with non-galvanically isolated measurement inputs. In a single phase system, analog and digital instruments are selected to measure voltage, current, frequency, and power factor.

The analog instrument indicates the point of the measurement scale on which it is located, indicating the upper and lower limits. Some of the typical applications of RS-485 is point of sale equipment. RS-485 can send data 1200 meters on cable. The RS-485 application in heating, ventilation, air-conditioning unit. Capabilities are used in the converter system made according to the following statement: monitoring parameters NCP series controllers, Modbus TCP network, handling controls: MN300, MN440, MN500, MN620, and heat meters - Mbus, the possibility of a software change controls, administration of the converter through a local or external PC terminal (TELNET), downloading and saving configuration files and files with FTP-client data (data downloaded, read and written by the application visualization once a day - which ensures the continuity of their records in the form of graphs), data storage (512 kB RAM with battery backup - data are recorded every 10 min, for 72 hrs.).Control and monitoring heat in Kolobrzeg installed by a company PUP SPIN SA in cooperation with the company TechBase Sp.

The communication is based on Modbus TCP converters to Satchwell ™ MN300, MN440, MN500, MN620 (485 NCP protocol) type I-7188E2-S-NCP. As a communication protocol Modbus TCP is selected as the Ethernet due to its versatility, the continuing growth and various protocol converters, has now become the standard in industrial solutions.Built a separate communication network, based on radio Ethernet (WLAN) 802.11a, which uses a frequency of 5 GHz. Additionally, the Brainchild's standard Ethernet and optional RS-232/RS-422/RS485 communication enable users to access data onsite from a remote location via the RS serial interface or Ethernet networking. Most of the serial based devices can be easily integrated with the Ethernet protocols. The sizing of the measurement system begins with knowing the main parameters of the plant; in particular, from the characteristics of the protection switch, the type of distribution system, the rated current, rs485 cable the rated voltage and the type of busbar can be known. Multifunctional instruments can be used in different distribution systems. The instrument must be selected according to the type of distribution system.
