Engineers require data recording instruments that are truly flexible, that quickly and easily adapt to a variety of measurement applications. At the same time, Accountants and Financial Controllers demand the most stringent use of data acquisition and instrumentation funds - a constraint that often excludes the most convenient and useful products on the market. Now with the MMS3OOO-GP Series, Engineers and Accountants can both finally agree on the same product. The MMS3000-GP Series combines all the usual benefits of low-cost and ease-of-use found in single-purpose data loggers coupled with the power and sophistication of more expensive rack-mount systems. The MMS3000-GP Series allows you to measure and record a variety of measurement parameters in a single session. Each 4-20mA input channel can be individually scaled to measure, display and record data in the engineering units of your choice. A menu of commonly used engineering units is available for quick selection, but greater flexibility is achieved by allowing the user to also create your own units with simple text entry from the MMS3000 keypad. Along with your standard transducers the MMS3000-GP Series can measure, display and record virtually anything. Do you need to review data in the field or on the plant floor away from the PC? Then the MMS3000-GP4 and GP8 are your instruments of choice. The large LCD enables you to graphically review recorded data by simply pressing a few keys. Windows based software for flexible data manipulation. Producing a variety of graphs and printout options. Wouldn't it be a welcome change to have a single easy-to-use product that is flexible enough to suit all your data logging needs? The MMS3000-GP Series is the answer you have been looking for. Below are some of the many Process Variables that are compatible with the MMS3000-GP Series: Pressure Temperature Relative Humidity Light Intensity Flow Rate Level / Depth Displacement Velocity Force / Load pH Position Power / Current / Voltage User Manual Product Specification PDF Document Software/Firmware ITEM SPEC REMARKS Model: MMS3000-GP4 & GP8 4 & 8 Current Loop Input Channels with General Purpose Converstion Software   CURRENT RANGE Nominal current range 4 to 20mA 4mA corresponds to 0 units (units selectable in software), 20mA corresponds to full-scale indication.
