4 INTERFACE CONNECTIONS AND DATA MEMORY (9500 ONLY)
Stored data can be accessed by recall to the instrument display (see ‘View
Log’). Alternatively, data can be accessed using a PC:
 Connect the instrument to the computer via the USB port, using any
suitable USB cable, ie YPT 746
 Turn the instrument ON and select SYSTEM mode from the ‘Options’ menu
 Scroll to ‘USB’ and select either ‘Hard Drive’ or ‘COM Port’.
‘Hard Drive’ – Once this option is selected, simply turning the instrument ON
while it is connected to a PC will cause an extra hard drive containing the
instrument files to appear on the PC. The log of test results is in text file:
‘9500_LOG.txt’. The other files shown on screen contain calibration and operating
systems for use when upgrading the instrument and should not be accessed.
The log file can be copied from the instrument by dragging between windows.
Once copied, the file can be opened with many text editors, word processors
or spreadsheet programs.
Note: Deleting this file from the instrument’s hard drive will clear the data
from the instrument memory.
‘COM Port’ – Once this option is selected, data can be downloaded from the
instrument to the PC:
 Open the ‘Virtual COM Port – HyperTerminal’ window on the computer
 In the instrument SYSTEM mode, scroll to ‘View Log’ and select ‘Download’.
 The data from the log will appear on the PC screen and can be transferred
to other PC applications or printed.
‘Unplugged’ – Note that the ‘Hard Drive’ or ‘Com Port’ may only be selected
while the instrument is being powered via its USB port. If the instrument is
running on batteries and is not connected to either a PC or a YPT783 external
power supply, an ‘Unplugged’ message will be displayed instead of either
‘Hard Drive’ or ‘COM Port’.
