The BK Precision DAS240 Portable Multi-Channel Data Recorder, 20 Channels, No Battery measures parameters commonly found in process applications including voltage, temperature, current, resistance, frequency and pulse. This model includes 20 universal analog channels with convenient screw input terminals that can be expanded up to 200 channels. Measurement results can be viewed graphically and numerically on a 10 inch color touch screen and saved to internal memory or an external USB memory stick. Icon-driven menus make the instrument easy to navigate. The free DasLab Windows PC software allows users to remotely control and configure the recorder, transfer logging results and configuration files, and view live data in graphical or numerical format on the PC. The DAS240's built-in VNC capability, based on the Remote Frame Buffer protocol (RFB), provides a graphical desktop sharing system to remotely control the instrument from another computer. VNC is platform independent and provides a means to control all functions of the instrument through a graphical interface replicating the instrument's front panel using a mouse and keyboard.
