higher capacity scale must be in the normal mode (see Step #5 above). (Contact
your Authorized Setra Dealer or the factory for more cabling information.)
The dual scale system is now set up. Test the system by following the procedure
below.
USING A DUAL SCALE SYSTEM
After performing the dual scale setup procedure, some of the scale’s functions
change. The most important change is in the APW function which transmits the
average piece weight and ID# from one scale to another. To sample and count using
a dual scale system, perform the following steps:
1. Press the zero key on the sampling scale and then on the bulk counting scale.
2. Tare or zero the container weights (if any) on both scales.
3. Place a known number of pieces on the pan of the sampling scale.
4. Enter that number into the sampling scale and press the count key.
5. Enter the part number (if any) on the sampling scale and press the i.d. key.
6. Press the apw key. The part number and average piece weight will be transmit-
ted from the sampling scale to the bulk weighing scale. The bulk weighing
scale will automatically be counting.
7. Add pieces to the bulk counting scale.
To view the average piece weight on either scale, enter ./rcl then apw . The average
piece weight is displayed but not transmitted.
Pressing the print key on a scale set in the dual scale mode will cause “UnAbLE” to
be displayed. Always print from the bulk weighing scale which should
not
be set to
operate in the dual scale mode.
Better accuracy may be achieved through the use of the accuracy enhancement,
minimum sample size, and minimum accuracy features of Setra scales. Use these
features on the sampling scale.
