It's the scales that count
A new range of industrial counting scales suits the needs of a variety of industries where parts counting is essential for inventory control, packaging checks and component handling.
Alarming performance from weighing scales
Adam Equipment has introduced a new range of industrial weighing scales to suit the needs of a wide variety of industries from building supplies to electronics manufacturing.
Dawn is a versatile tool that is designed to acquire data from networks conforming to both CAN and J1850 standards.
Dawn not only acquires data from the vehicle's sensors via the network, but also allows the user to add sensors to acquire this information directly with A/D hardware.
The data from both the network and A/D are acquired simultaneously.

Fast response from oxygen analyser
The Series 2700 fast-response oxygen analyser uses an advanced, compact paramagnetic oxygen sensor to provide accurate and repeatable results with millisecond response times.
As these data are acquired, Dawn will display the data in real-time as a y-t or x-y plot, as a stripchart, or as a meter (digital, analogue or bar).
Up to 64 channels of data (parameters) can be overplotted on one graph, and up to 100 graphs can be displayed on one page (screen).
The user has the ability to define eight independently configured display pages to quickly see the data required.
Advanced versions of Dawn will analyse the data in the time and frequency domain, making it ideal for advanced vehicle analysis, pass/fail testing, vibration testing, monitoring and diagnostics.
Dawn integrates HEM Data's Snap-Master data acquisition and analysis software with various hardware options including an external box, PCMCIA card, or a plug-in PCI card.
This makes Dawn ideal for in-vehicle or laboratory testing.
Dawn works with hardware from Cubic Systems and National Instruments.
Cubic Systems hardware works with both CAN and J1850 protocols, while the National Instruments hardware focuses on CAN.
Snap-Master also works with over 250 models of A/D hardware including those manufactured by Dataq, Measurement Computing, Keithley, National Instruments and IOtech.
Snap-Master supports digital I/O, analogue output and counter/timer functions.
Snap-Master is also ideal for post processing of data.
Dawn is targeted to work with every major car and truck manufacturer and their suppliers.
Data can be acquired from the vehicle or from a subsystem on a test bench.
Dawn also acquires data directly from sensors that output CAN data such as a GPS unit and a data logger from Corrsys-Datron, and from industrial networks.
A message monitoring mode is available in addition to acquiring data in engineering units.
A major benefit of Dawn is that it unburdens the user from working with raw hexadecimal messages, and makes it easy to acquire data by specifying specific parameter names, such as "engine rpm" or "ABS telltale".
Dawn handles the conversion of the network messages to parameters with a built-in database which automatically configures the communication with the vehicle network.
This allows the user to quickly select a specific parameter by name and see the data displayed in engineering units.
DAWN works with any Pentium PC or higher with Microsoft Windows XP/2000/NT.
