Concept
DPM-3-DLS data logging software
turns a PC connected to up to 31 DPM-3 instruments into a powerful,
low-cost data logging system.
Data can be displayed on
the computer screen in the form of up to 64 simulated meters in
4 groups (or screens) of up to 16 meters each. The on-screen simulated
meters can show the readings and alarm indications of selected
actual meters, or show values other than those normally displayed
by meters, such as peak value. They can also show calculated parameters,
or weighted averages that combine data from multiple meters. For
example, a virtual meter can display the sum of any number of
meter by adding them together. Available operands are multiply,
divide, add, and subtract, with parentheses to allow complex expressions.
The on-screen position and appearance of individual meters is
user selectable to achieve meaningful groupings.
Data can be logged from selected
meters into an ASCII file, which is easily imported into MS Excel
for graphing and analysis. User settable parameters include the
logging time interval in seconds, the separator character (normally
a comma), and header data (with or without time and date). Data
files can be password protected.
Hardware
Up to 31 DPM-3 meters can be connected
to the PC in addressable multidrop fashion using a single RS-485
line. Each of these DPM-3 meters must be equipped with an RS-485
board. A single DPM-3 meter can be connected to a PC using an
RS-232 line. That DPM-3 must be equipped with an RS-232 board.The
computer must be PC compatible, operate under MS Windows 95 or
higher, and have an available COM1 to COM9 serial port.
Software Installation
The DPM-3-DLS Data logging Software
can be downloaded from this website at no charge. Click
here to download the self-extracting install file. The
free download version allows operation in the Demo Mode, which
provides a good indication of the capabilities of the software.
Connection to actual instruments requires a 12-digit activation
code, which will be emailed by Transducer Techniques upon full payment. This code must be installed within 10 days of issue.
