Zero
adjustment* Zero and span adjustment are made in three different speeds:
 If you press the arrow key to the desired direction repeatedly, the value will
be changed slowly.
 If you press the arrow key continuously the value will be changed with
medium speed.
 If you press the other arrow key while pressing the desired direction’s key
continuously the value will be changed quickly (coarse adjustment).
Unload the scale. Adjust the analogue output to 0 V or 4 mA by using the arrow
keys (increase) and (decrease).
Save by pressing the key. If you press the key without pressing any
arrow key you will skip this step.
Span
adjustment* Load the scale. The load value must be between 10% and 100% of the
maximum weight to measure. Adjust the analogue output to the required value
for this load by using the arrow keys keys (increase) and (decrease).
Save by pressing the key. If you press the key without pressing any
arrow key you will skip this step.
Setpoint
entry Put a load equal to the desired setpoint value on the scale.
Press to assign this value as the first setpoint value (O1) OR
press key to assign this value as the second setpoint value (O2).
Save by pressing the key. If you press the key without pressing any
arrow key you will skip this step.
Filter
selection High filtering (lower frequency cut-off; longer settling time; factory default)
If you press the key in this step, the filter type will be set to “High”.
Low filtering (higher frequency cut-off; shorter settling time)
If you press the key, the filter type will be set to “Low”.
For increasing the stability of the weighing system try the “High” filter first. If you
need a faster response in your application set the filter type to “Low”.
Save by pressing the key. If you press the key without pressing any
arrow key you will skip this step.
Exit and save
