Chapter 7 Troubleshooting

The ultrasonic flowmeter has advanced self-diagnostics functions and displays
any errors in the upper right corner of the LCD via definite codes in a date/time
order. Hardware error diagnostics are usually performed upon each power on.
Some errors can be detected during normal operation. Undetectable errors
caused by incorrect settings and unsuitable measurement conditions can be
displayed accordingly. This function helps to detect the errors and determine
causes quickly; thus, problems can be solved in a timely manner according to the
solutions listed in the following tables.
Table 1 applies when errors caused by incorrect settings and signals are detected
and are announced by error codes displayed in Window M08.
