Rice Lake DWM-IV Weighmeter Standard Operators Manual - Manual (Page 21)

Used to control the automatic ZEROING of the scale. It will automatically track small
drifts in weight such as caused by small amounts of debris, rain, or thermal drift.
Tracking width sets how much drift can be automatically zeroed out. Example, if you
have a truck scale with 20 lb increments and your tracking width is set to 3, anything that
weighs 60 lb or less will be zeroed out. This may not be desirable if you are using your
system for filling/batching and have a very slow fill rate or if you are trying to weigh
very small items (which is not recommended) as the tracking may happen faster than you
are filling and will cause it to appear that the scale is not working.
F1.6 - 2% Zero Range
Will prevent the scale from being “Zeroed” if the reading is more than 2% of the capacity
set in F6. Useful to prevent accidental re-zeroing and subsequent restarting of batch
systems when a batch is already being processed.
F1.7 Right Hand Keyboard Enable
Turns on/off the right hand side of the keyboard. Has no effect on the four (4) function
buttons under the display.
F1.8 Output Options
Controls the function of the J4 connector on the mother board. Should be disabled if not
used as it will slow down the system.
F1.9 High Resolution Mode
Allows you to bypass the normal four (4) raw counts per digit requirement that would
limit you to about 24,000 display units. You should not use this unless necessary as
neither the internal circuitry of the A/D board nor the load cells connected to it were
designed for such extremes.
F2.0 Tare Enable
Controls whether or not the front panel [TARE] button will operate. The tare function
should be used to remove an empty container weight without having to zero the scale.
When the [TARE] button is pushed the scale will enter the tare weight automatically and
switch to the net mode. You can switch between the gross mode and net mode using the
[GROSS/NET] button.
F2.1 Tare Interlock
Prevents the tare from being cleared if the scale is not at zero. Used mostly to prevent the
accidental clearing of the tare value while it is still in use.
