5.2.1 Operating elements
3 operating keys, "-", "+", "E".
Esc/back function: press "-" and "+" simultaneously.
Enter/confirm entry: press "E"
14 function keys:
Start/stop function: Pressing the "Start" button starts a batching operation. Press the "Stop"
button once to pause the batching operation currently in progress. Press "Stop" a second time to
abort the batch. Pressing start again restarts the batch cycle.
C function: Press "C" when batching is stopped to reset the counters on the display to their
original values.
Print function: Press "0" and "." simultaneously to print out the last batch cycle. The "RS232
printer interface" feature must be purchased to be able to use this function.
5.2.2 Function for entering a value for the preset counter
A value for the preset counter can be entered any time. This value can either be entered in the
Display menu, or by pressing one of the keys 0-9 or period. It does not matter whether a batching
process is currently active when you enter the value. The new preset counter value is used when
the next batching process is started.
!
Note!
If the preset counter is part of a display group, the preset counter value which is valid for the
current batch is always displayed. If the value is changed when the batching process is stopped,
the new value appears immediately on the display. However, if the value is changed during an
active batching operation, the old value of the preset counter, which still applies for the current
batch run, is displayed until this batching operation is finished. The new value, which is valid
for the next batching operation, is displayed directly afterwards.
