Factory
Settings
Reset function is used to revert the instrument parameters back to the
initial factory settings. When displaying the current output (menu
number 4.2), press key to enter the reset function. Display in LCD
is as follows.
Press to enter the reset menu and select reset for factory settings.
Adjust
Distance Adjust setting can be used to as an additive correction to the
measurement if the gauge output and true distance do not agree. When
LCD displays the number menu (menu number 4.3), press key to
enter the distance adjust menu setting. Display in LCD is as follows.
Press to set the distance. Note that that the value should be
modified prior to changing the sign of the offset.
Distance Offset = Actual Distance to product - Measured Distance to
product
(Notes: This parameter is sign sensitive. Before committing the value
ensure the -/+ sign is correctly selected. This menu needs to be operated
by professionals)
Threshold
Threshold setting is used to set the threshold limit of the effective echo.
The higher the threshold setting is, the higher the echo amplitude
required to trigger the level measurement. In turn, this eliminates small
signal clutter interference. Note that if the modified threshold value is
larger than the effective echo amplitude, no or false measurement might
result. The default range of echo threshold is 8 DB. See Figure 5-2 for
the definition of this parameter.
