INTRODUCTION
The Rad-87 can store up to 72 hours of trend data captured at 2 second intervals.
(Additional parameters/measurements may affect trending capacity). 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 device 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.
TRENDCOM UTILITY INSTALLATION
Copy the TrendCom utility from the TrendCom CD onto a PC running MS-Windows.

The Rad-87 will display “dat out” while trend data is being transferred. A progress bar
will advance to indicate the status of the download. Larger trend files will take longer
to download. Transfer time is approximately 20 seconds per hour of trend data.
NOTE
: During download of trend information, all normal Rad-87 functions are unavailable
and the keypad is locked, except for the power button.

ERASING TREND MEMORY
To erase (clear) the trend memory, set the Clear Trend option to Yes and press the Enter
Button to accept the setting and clear the data from the memory. Refer to the Clear Trend
menu located before this Trend setup and use section.
The Rad-87 continuously trends data. When performing a new study and gathering data
on a new patient, it is highly recommended the "clear function" be utilized in order for the
results to be separate.
Turning the Rad-87 off will not erase the trend data
