DW800/820 Operation Manual Jumper Settings In order for the 800/820 to operate as desired hardware, Jumpers must be set properly.
DW800/820 Operation Manual Weighing Operation Weigh Keys: During weighing operations the keys are used as follows: The ZERO key is used to return the scale to the center of zero. The TARE key is used to tare the weight on the scale. Place the empty container on the scale and then press the TARE key. The display will indicate the new weight. The PRINT key is used to print a weigh ticket. The GROSS/NET key is used to change the displayed weight from Gross Wt. (tare + net = gross) to the Net Wt.
DW800/820 Operation Manual Counting Operation The Counting Operation cannot be accessed, if the NTEP parameter is set to True (see parameter setup) or the Units of Weight parameter is set to LB/KG, LB/G, KG/G, or ALL. The Count Operation is started by pressing and holding the UNIT key. The indicator will toggle thru all allowable sample sizes, starting with the current sample size. When the desired sample size is displayed release the UNIT key. The indicator will sample the pieces and display the count.
DW800/820 Operation Manual Parameter Setup Operation Parameter Setup may be accessed using the following method: 1. From the Weigh Mode press and hold the GROSS/NET key. The DW800/820 displays “GRSNET” to signify that the GROSS/NET key has been pressed. After approximately 3 seconds the indicator displays “PARAMS” at which time the key may be released. NOTE: Jumper J8 must be removed from the NTEP position, if NTEP is being utilized, before access to Parameter Setup is allowed. 2.

DW800/820 Operation Manual 2. Once access is allowed to Parameter Setup, the NTEP parameter, along with its current value is displayed. NOTE: NTEP should always be set to F, unless used. Press the Print Key to move to the next parameter. 3. PARAMETER SETUP AND CALIBRATION PAGE 9 Press the PRINT key or ZERO key to select, FCAL, the scale calibration and configuration parameter. 4. Next parameter “FCAL F” change to “FCAL T” using the TARE key.
DW800/820 Operation Manual PARAMETER SETUP AND CALIBRATION Page 10 Printer Drivers The DW800/820 can be provided with the following optional print drivers. Each driver is programmed specifically for each printer and will not work with any other printer. Only the computer and scoreboard outputs are available with any DW800/820 shipped without a printer.
