3.3.2 AUTO TOTAL
The
Fx-TOTAL
key under the AUTO TOTAL mode functions as auto total on/auto
total off:
The auto mode has three variations which are programmed in the setup menu:
• AutoLoad – Any settled tension above the ‘rise above’ threshold will be
automatically totaled. Then the Dyna-Link must fall below the ‘drop below’
threshold before another total is allowed.
• AutoNorm – This mode takes the last settled weight to auto total with. The total
occurs only once the scale goes below the threshold. This allows the load to be
adjusted without a total occurring. Once the load is removed, the scale uses the
last settled reading for total.
• AutoHigh – Similar to the AutoNorm mode except the scale uses the highest
settled reading. Useful for loads that can’t be removed all at once.
3.4 Clear Total
The
Fx-VIEW TOTAL
key activates the total weight display followed by the number of
samples. While the display is showing the total, total is cleared by pressing
ZERO
.
3.5 Net / Gross
Switches the display between net and gross modes. Net tension is defined as gross
tension minus a tare weight.
To switch between net mode and gross mode:
1. Press the
Fx-NetGross
key (setup to the net/gross function).
2. The
Fx-NetGross
key will only function if a tare value has been established.
3. Switching back to gross mode from net mode will not clear the tare value. This
allows the operator to use the gross mode temporarily without having to reestablish
the tare value. Only clearing the tare or setting a new tare will change the tare value
held before switching into gross mode.
3.6 TARE
In force measurement applications, tare is useful as a way to display differential force.
By taring out a known force, only positive and negative deviations from the tared
force are displayed. This can also increase accuracy as any initial error is removed
leaving only slope error. In scale applications, tare is typically used to zero out a
known weight such as rigging, a packing container, or pallet and display the load in
NET
tension/weight. To use tare, one of the two function keys must be configured to
the
TARE
function. A tare value is entered by pressing the
Fx-TARE
key. The
TARE
function in the Dyna-Link 2 is defined as a tare-in/tare-out operation. The first press
of the
Fx-TARE
key stores the current tension/weight as a tare value and then the
Dyna-Link subtracts the tare value from the gross tension and changes the display to
NET
mode. The next press of the
Fx-TARE
key will clear the tare value and revert the
display to
GROSS
mode. The optional RF remote display has a
TARE
key
permanently available.
