AUF760 Series Operation Manual OP760.1.1.7ENG 2.17 Install Question 1. Pipe parameters entered must be accurate; otherwise the flowmeter will not work properly. 2. During the installation, apply enough coupling compounds in order to stick the transducer onto the pipe wall. While checking the signal strength and Q value, move the transducer slowly around the mounting site until the strongest signal and maximum Q value can be obtained.

AUF760 Series Operation Manual OP760.1.1.7ENG 3.9 Damping The damping function will stabilize the flow display. Essentially, it is a part of the signal filter. Enter a coefficient in Window M40. Increasing the coefficient increases the stability. However, the measurement displayed may be slightly delayed due to over damping. Logging too long may result in no response to real-time fluctuation, especially when flow rate fluctuates wildly.
AUF760 Series Operation Manual OP760.1.1.7ENG 3.14 4~20mA Current Loop Verification Possessing a current loop output exceeding an accuracy of 0.1%, the AUF-760 is programmable and configurable with multiple output modules such as 4 ~20mA or 0~20mA. Select in Window M54. For details,please refer to Chapter of Windows Display Explanations.
