At the completion of a test, the Function button command selection at the bottom of the LONGITUDINAL
BALANCE TEST RESULT screen consists of six options available to the operator. The following are brief
descriptions of each of the Function button options:
SHOW REF Pressing the function button corresponding to SHOW REF allows a user to
overlay a REFERENCE MASK over the test result on screen to compare the
two. See Section 5.4 for more information about the REFERENCE MASK
feature.
Pressing the SAVE / UPLOAD button shows a pop-up window where the user is allowed to upload results,
and save results to internal memory or to external USB memory.
UPLOAD RESULT Choosing UPLOAD RESULT from the SAVE / UPLOAD pop-up menu sends
the result that appears on the CableSHARK screen (current test or recalled
test) to a PC via a NULL modem cable. The remote control program Visi-
SHARK can be used to capture and analyze the results on a PC.
SAVE TO MEM Choosing SAVE TO MEM from the SAVE / UPLOAD pop-up menu invokes
the SAVE SESSION menu. From here, the test results can be saved to
internal non-volatile memory. See Section 5.3 for more information.
