Setting Impulse Response
The Impulse Response option enables you to force the meter to
transmit in one direction only, without changing the AGC setting.
You can then diagnose problems with transducer, pipe, or fluid
configurations. To enter the option, scroll down to the Impulse
Response entry in the Service Menu and press [ENTER]. The
screen appears similar to Figure 9-24 below.
