Force Transmit Procedure
This diagnostic software routine allows the user to “force” a transmitting condition that can be use to search for an amplitude level (ALC) when Detection Fault or Low Signal alarms are present. The routine forces the flowmeter to generate constant transmit bursts while reporting current receive signal strength for the user. To initiate the Force Transmit function, refer to the example shown below.
1.After [Install] is selected press <ENT>. While the flowmeter is going through the drives (see menu screen below), press the <ALT> and <MENU> keys simultaneously.

NOTE: The <ALT> and <MENU> keys must be pressed before the meter scans through all the drives, or the selection of the detection mode and the Force Transmit function must be initiated again.
2.A typical menu screen will appear as shown below and indicate the current ALC (e.g., 50).
This ALC number indicates the current receive signal strength and can be used for further diagnos- tic purposes.
