Epson USN 52L, Operating Manual, Page: 56 / 207

Krautkramer USN 52R/USN 52L Issue 05, 02/00 5-11
Operation:
The MULTECHO setting of the function MEASURE
(lower operating level) is a prerequisite for operation.
• Simultaneously press
N
and
O
in a-WIDTH or
a-THRESH in 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-THRESH with
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-START you 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-WIDTH you determine the width within
a range from 1 to 5000 mm (continuous).
Operation:
– Set the gate position in a-START and a-WIDTH
with the assigned
M
keys.
