Trend Setup and Use
Introduction
The Rad-87 can store up to 72 hours of trend data captured at 2 second intervals. The trend data
can then be transferred to a PC for evaluation. A serial cable is required to connect the Rad-87 to
a PC. Patient monitoring is not possible while trend memory is being transferred to a PC.
Trend data is stored in non-volatile memory, so it is not erased when the instrument is shut off. A
trend data download is initiated using the TrendCom utility which downloads the trend data and
saves it to an ASCII text (.out) file with an output delimiter option.
NOTE: Rad-87 Serial Ouput must be set to ASCII 2 for successful download of trending data.
Refer to the Serial Output menu and settings located farther in this chapter.
NOTE: Rainbow Acoustic Monitoring trending is not available.
TrendCom Utility Installation
Copy the TrendCom utility from the TrendCom CD onto a PC running MS-Windows.
TrendCom Utility Operation
NOTE: Patient monitoring must be suspended while downloading trend data from the
instrument. Ensure the appropriate USB-Serial software driver is installed on the PC,
if using a USB-Serial cable. The PC must have Microsoft Excel spreadsheet software,
or another program capable of opening a .csv (comma separated value) file to view
trend information. Trend information data is limited by the instrument’s parameters.
