This chapter describes how to manage special waveform functions of the EPOCH 650
ultrasonic flaw detector.
6.1

Reject

The Rcvr > Reject parameter allows you to eliminate unwanted, low-level signals
from the display. The reject function is linear and adjustable from 0 % to 80 % FSH.
Increasing the reject level does not affect the amplitude of the signals above the reject
level.
The reject function can also be used in the unrectified Rcvr > Rect = RF mode.
The reject level is displayed as an horizontal line on the instrument display (see
Figure 6-1 on page 116) or two lines in the case of the unrectified Rcvr > Rect = RF
mode.
