Revised 07/07/08 dranetz-bmi.com DranetzMPad 7/9/08 3:23 PM Page 2 For temporary but critical on-site data acquisition, the portable, high-speed MeasuringPAD™ offers a convenient, economical alternative to an elaborate test and measurement installation. This sturdy hand-held instrument can be used in a wide range of manufacturing, laboratory, plant operations, and quality control applications. Rapidly collecting, monitoring, and displaying multiple sensor inputs, it can be used for troubleshooting, maintenance, process tuning, fault recording, trend analysis, and much more. Configured and operated through an easy-to-use color touchscreen interface, MeasuringPAD continuously scans all active inputs, digitizing with 16-bit A/ D while checking for limit-violation triggers and refreshing its memory buffer of 10 kHz per input. Real-Time Data Monitoring MEASURING MeasuringPAD provides live readout of up to sixteen differential analog inputs and up to eight logic-level digital inputs. As numerical measurements are monitored for exact conformance to user-entered setpoints, the vivid color-coded status display lets you size up your test or process at a glance. To ensure true PAD “finished-answer” readability, analog signals are easily scalable to desired engineering units. Convenient input “pods” allow fast and easy hookup of machine- or process-dedicated sensors – including DC/AC Low and High Voltage sources (from 100 mV to 300 V), DC/AC Low Current sources (4 to 20 mA), and most Thermocouple types. Digital inputs are standard TTL-level signals from switches, contacts, encoders, pickups, and other frequency-generating devices. They may be used to trigger the logging of data, to perform programmable Using MeasurePAD’s unique counting and timing operations, touchscreen pages, setting up the and to monitor frequency and quadrature. Up to eight internal instrument literally takes seconds. Simple user selections and clear, cross-channel math calculations can also be set up to display and monitor additional process variables such as horsepower, efficiency, and corrected flow – plus signal intuitive pathing make the setup process both easy to use and easy to max /min and average values. learn. Once created, multiple test-specific setups can be stored for High-Speed Data Recording instant reloading. You can instruct MeasuringPAD to sample scaled measurements at a regular time interval – or, immediately on detection of any specified trigger event, to begin recording at a special rate that can be up to a microsecond-level “burst” speed. Instantly stored on a standard CF memory card in a simple and universally compatible ASCII text format, data records are both time- and trigger-stamped, and may be Multichannel Data Display directly imported by all kinds of third-party programs for post-analysis and report For instant operator interpretation of measurement results, the backlit color LCD furnishes real-time display of measured and calculated values in a number of programmable formats, including generation, without the need for special drivers or version-dependent operating • bargraph, for rapid visual comparison of up to sixteen systems. If desired, records of data active parameters values as they existed just prior to a triggering event can be included in • trend, for simultaneous, independent timeplotting of up to four the stored data file.
