P04 - - - - Maximum measuring distance (H)
The maximum measuring distance is the only parameter that has to be programmed for each application except for distance
measurement.
The values of the maximum measuring distance will be displayed in accordance with the table below.

The maximum measured distance (H) is the maximum distance, which can be measured between the transducer face and the farthest medium
surface. The factory defaults of
maximum measuring distance values (X
M
), which can be measured by the units, are listed in the table below.
For the actual application, the P04 parameter must be set to the maximum distance to be measured i.e., the distance between the transducer
face and the bottom of the tank, where H <= X
M
.

Keep in mind that
LEVEL (as the result of the measurement) is calculated according to the following formula: P04 (programmed) –
DISTANCE (measured by the device) (LEV = H - DIST). Since the accuracy of level (and all further calculated) value depends on the accuracy
of P04 (the max. distance to be measured of the application), to obtain the highest accuracy, it is recommended to measure this distance in the
empty tank with the EchoTREK by using the “GET LEVEL” function (press
and keys simultaneously) provided the bottom is flat.
Save by pressing ENTER the actual measured value displayed as P04.
FACTORY DEFAULT: maximum measuring distance (X
M
) according to the table.
