The TF1100 ultrasonic flow meter 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. Errors displayed in the TF1100 are divided into two categories: Table 1 is for errors displayed during self-diagnostics upon power on. “* F” may be displayed on the upper left corner of the screen after entering the measuring mode. When this occurs, it is necessary to power on for self-diagnostics once again to detect and solve possible errors using the table below. If a problem still exists, please contact the factory or the factory’s local representative for assistance. Table 2 applies when errors caused by incorrect settings and signals are detected and are announced by error codes displayed in Window M07.
