Messages

shown on the LED. Selecting meter display “0” (which is the default) will display the active
status message as shown in Table 11 or Table 12, except if there is a fault (requiring a
message) or some other information has been requested.
Alternatively, parameter P5 or P13 can be set to select a message (1 to 19 as shown in
Table 13).
