Menu item Description
Put Trace on Hold
Makes an exact copy (blue trace) of the “live” trace.
NOTE: This function is very helpful when making a phase
comparison on a 3 phase circuit. It is also very helpful
when just using the TDR function on low voltage cables
with 2 or 3 phases and by comparing them. Typically
this will show the location of the fault in one of the
phases provided the fault is either an “OPEN” or a
“SHORT” or shows enough of an impedance change
compared to the impedance of the cable.
Set Marker at
Current Cursor
Position
Places an additional marker (green) at the cursor position (red). As only one
additional marker can be placed, the very last marker is erased every
time the marker is placed on a new position.
Save Current
Trace
Saves the current screen view to the internal memory.
Export, Recall or
Delete Stored
Traces
Enables you to export, recall and delete stored data from internal memory.
By selecting All traces you can delete or export all traces which are currently
stored in the internal memory.
In case you want to select a specific trace, you need to select the recording
date first. You are then allowed to scroll through preview pictures of all traces
stored on this day.
After you selected the desired trace(s), you can choose from the following
options:
Export Copies the selected trace(s) to the EtrayTraces folder on the
USB flash drive which has been plugged into the USB slot .
The data can be viewed in any regular web browser by opening
the
index.html file which is also located in the EtrayTaces
folder.
Remove Removes the selected trace(s) from internal memory.
