will be displayed first. The upper row of the display panel displays the instrument
model and software version number, and the lower row displays the version date. Then,
the internal self-test of the instrument starts. If any error is found, the error code
number will be displayed. Multiple errors will be displayed for a certain time in turn,
and then the normal working cycle will be started. If the process number is set,The
correspond workflow will be automatically started.
Inside this instrument, there is a button cell to save the working state before
power failure, and these states will be recalled after power-up. For workflow, after
power-on, the process controller will perform a power-on trigger function, and if the
process has corresponding operations, it will be executed.
After the power supply is turned on, if all the following conditions can be met,
the instrument will perform a weight zero setting, which is to set zero for startup:
(1) The workflow is not in the control state of feeding or discharging.
(2) The weight can collect stable data within 6 seconds after power-on.
(3) The weight value is within the range of starting and zeroing (see F parameter
table F04).
