6.10 Master Reset
A normal reset is executed after interrupting auxiliary power and when the integrated
watchdog is triggered, i.e. neither measurement data nor parameters are deleted.
However, if you would nevertheless like to delete all measurement data and reset the
parameters to their default values, a master reset must be executed using the keypad at
the U1601 summator. This is only possible within the first seven seconds after switching
the summator on. Press and hold the following keys simultaneously for at least three
seconds to this end
:
Master reset can also be triggered with the following ECL command: SYSRESET = 590.
The master reset is now performed, after which the instrument returns to its normal
display. The following parameters are not effected by the master reset:
ID
Baud rate for the RS232 interface
Parity for the RS232 interface
BUS/L and BUS/R parameters Linking of the status relay
