3.1 Verification
1. Install unit, configure for application, and view echo curve.
The echo curve should be saved from -3 ft (-1 m) to 3 ft (1 m) beyond the reference
height.
2. Verify that the unit reads correctly while the chamber is empty.
The unit can be set up to read 4 mA as zero level when the chamber is empty. Or, it may
read saturation value of 3.8 mA when the level is sufficiently below the zero level.
3. On the echo curve, note the following:
