Epson USN 52L Thresh Determination of threshold, Start Start of the gate, Width Width of the gate

Adjustment of the USN 52R/USN 52L Operation

Operation:

The MULTECHO setting of the function MEASURE (lower operating level) is a prerequisite for operation.

•Simultaneously press Nand O in a-WIDTHor a-THRESHin order to switch to the settings for Gate b.

a-THRESH Determination of threshold

With this function you determine the threshold for the selected gate. You can set a range from 10% to 90% screen height in 1% steps.

Operation:

–Set the required threshold value in a-THRESHwith

M.

The selected gate is displayed as a line.

If there is a violation of the set threshold (signals ex- ceeding or falling below it), an alarm is activated.

The exact gate position is defined by two further parameters:

•Gate start (a-START)

•Gate width (a-WIDTH)

a-START Start of the gate

In the function a-STARTyou determine the start of Gate a within a range from 0 to 5000 mm (continuous).

a-WIDTH Width of the gate

In the function a-WIDTHyou determine the width within a range from 1 to 5000 mm (continuous).

Operation:

–Set the gate position in a-STARTand a-WIDTHwith the assigned M keys.
