Operating Instructions
A. DISPLAY
The display indicates the arithmetic result of the analog signal derived from the scale
base. The display indicates: OLOAD at 102% of capacity and above.
B. STATUS INDICATORS
The DWM-IV illuminates a triangular arrow above the proper legend for current status of
the display. The status indicators are:
1. SEL - illuminated while accessing the front panel options.
2. ZERO - illuminated when the scale base is within +/- 0.25 increment of zero
3. TARE - when lit, indicates that a tare value is being displayed.
4. NET - when lit, indicates that a non-zero tare value is currently being used.
5. PIECES - illuminated when in the piece count mode to indicate that the display is
showing pieces instead of weight.
6. F1 - Future option. (not labeled on standard units)
7. F2 - Future option. (not labeled on standard units)
C. KEYBOARD
1. [Zero] Button: This button allows re-zeroing of the scale over a +/- 2% range of scale
capacity or full scale capacity (programmable). During set-up, the automatic zero tacking
may be disabled if desired. This button must be pressed for approximately two seconds to
capture zero.
2. [Tare] Button: This button is used to remove the container weight value from the
weight indication. When pressed with weight on the scale no motion present, this tare
value will be stored and subtracted from the gross weight to indicate a net weight display
of zero. Pressing the [TARE] button places the system in net weighing mode.
