Operation while not Scanning
3.3.1
Mode switching
This radar can scan test/display data in both "B mode (vertical cross section)" and "BA mode
(vertical cross section and reflected waveform display)". When the display mode is switched
between "B" and "BA" after scanning, data scan tested in "B mode" is displayed in "BA mode," and
data scan tested in "BA mode" is displayed in "B mode." (See Figure 3-10.)
When the “
Distance feed system
” method is being used as the “Scan test method”, one screen
displays 49 cm of sense test (movement) distance in “B mode” (maximum recordable test distance
is 15 m). In “BA mode” one screen is the same as in A mode, which is 32.5 cm shown in B mode
(maximum recordable scan
test distance is 15 m).
The A-mode (waveform display) portion in BA mode indicates the waveform at the vertical cursor
position in BA mode.
Perform the following procedure to switch between the "B mode" and "BA mode:"
a)
Push 4
SET
while scanning is stopped and switch to the parameter settings screen.
b)
Select the settings item “Display Mode” using the ▲▼ cursor keys (invert display) and
transfer to item selection using the cursor keys.
c)
Select “B” or “BA” using the ▲▼ cursor keys or use the
cursor keys to transfer to
set up items.
d)
Push 4
SET
to switch to the scan test screen.
Remarks
•
If the display mode is switched from “B” mode to “BA” mode or vice versa when the scan
testing stops then the display mode last selected when the scan testing restarts will be in
operation when scan testing is resumed.
