CHAPTER 4: ADVANCED FEATURES AND OPERATION
4.1 UNIT WEIGHT ENTRY
The APW may already be known from using another scale, an engineered standard or from
a bar coded label. If you already know the APW (Average Piece Weight of the items you
wish to count, then use one of the following procedures.
4.1.1 APW ENTRY FROM KEYBOARD
1. Press the “Sample” soft key. The scale prompts you to add pieces to the platter.
2. Press the “APW” soft key. The scale prompts you to choose either KEYIN or
TCS.
3. Press the KEYIN soft key. The scale prompts you to input the average piece
weight.
4. Using the numeric and decimal point keys, key-in the actual APW value.
5. Press the ENT key. If the unit weight is large enough, the scale will now display
the number of pieces on the scale. If it does not, the scale briefly displays an
error message, but still allows piece counting.
NOTE 1: If the scale displays a “Low Resolution” message, the unit weight of the
items you wish to count is too light for your scale to process accurately.
4.1.2 APW ENTRY FROM SCANNER
To use this method, you must have a working CCD or laser scanner plugged into the
COM2 port and the 650 scale must have printed the barcode you are scanning. See
section 5.4.7 for COM 2 setup.
1. If an APW is already showing on the display, press the CLR key twice to clear
APW from scale.
2. Aim the scanner at the APW barcode you wish to scan and press the trigger.
When the scanner beeps, the 650 scale will briefly display the scanned-in APW.
3. Place your parts on the 650 scale. If the APW is large enough, the 650 scale will
now display the number of pieces on the scale. If it does not, the scale briefly
displays an error message, but still allows piece counting.
4.1.3 UPLOAD APW FROM TC SERIES SCALE 1
To use this method, you must have either a 610 or a 630 scale connected to COM2.
See Appendix B for pin outs. NOTE: Scanner must be selected for COM2 in section
5.4.7.
NOTE: The 610 or 630 scale must be configured for “Transmit APW Mode”. See
scale manual for more information.
1. If an APW is already showing on the display, press the CLEAR key twice on the
650 scale to clear current APW.
2. Perform the sampling on the 610 or 630 scale.
1 Also works with PBS Series scale.
