If the device cannot find the level signal after you do the procedure in menu item 1.4.0 1.4.0 1.4.0 1.4.0
Application Setup Application Setup Application Setup Application Setup, then you can also manually change the threshold to find the signal. Do this
procedure:
• Look at the level pulse amplitude value on left side of the first screen in menu item 2.5.4 Level 2.5.4 Level 2.5.4 Level 2.5.4 Level
Threshold Threshold Threshold Threshold.
i Make a note of the amplitude of the correct level signal. Use this value to calculate the new
value for the level threshold. The level threshold value used at this time is shown on right
side of the first screen.
• Push [ ] to change the level threshold value.
• Increase the amplitude of the level threshold value. Push [>>>>] to move the cursor to the next
digit on the right. If the cursor is on the last digit, push [>>>>] again to go back to the first digit.
Push [
] to decrease the digit value and [ ] to increase the digit value.
i This value must be more than the incorrect signal. We recommend that you set the level
threshold at half the amplitude of the correct signal.

i The threshold increases. The device ignores the interference signal and uses the first
signal that it finds.
Interface threshold
The device uses Direct mode to measure the level and interface level of products. If there are
objects in the tank that can cause signal interference, change the interface threshold to ignore
them. Use the same procedure in How to use thresholds
