Scale Programming 35
•There are four types of setpoints which can be selected by setting SPC 04, Bits 1 and 0: % of Quantity (%QTY), % of Weight
(%WT), Over/Under Quantity (QTY), or Over/Under Weight (WT).
• When entering weight setpoints, be sure that you enter in the weight values with decimal point and all leading and trailing zeros.
• All percentage values must be rounded to the nearest whole number, fractional percentages are not allowed.
• Setpoints involving % of quantity or weight are limited by the decimal places available on the display. For example: if Set Point
value 1 specifies a Quantity of 9999999, then a Set Point value 2 of % of Quantity cannot be set for more than 100% because all
7 digits of the display are already in use.
Table 6-5 below shows what to enter in each of the two set point values to program each type of set point. The alarm sounds
with a rhythmic beeping at setpoint one and with a rapid beeping at setpoint two. For the Setpoint Alarm to be activated, SPC
02: SET POINT ALARM must be set to “0: ON”. See
Section 3.1.1 for instructions on how to set Customer specifications.
Here are some examples of how the setpoints can be programmed. These examples can be adjusted to fit your
application.
4. Press the MODE key to quit the Programming Mode and return to the Weighing Mode.
6.6 Resetting the Sequence Number to Zero
The DC-788 has the ability to increment a sequence number every time a transaction is printed by pressing the +
(Plus), - (Minus), or * PRINT keys. The sequence number can be reset to zero by carrying out the following
procedure:
1. From the Weighing Mode, press the MODE key twice to enter the Programming Mode.
2. While holding down the REZERO key, enter [.] [.] [7]. The display will read:
3. To reset the Sequence Number to zero, press the CLEAR key, or press the MODE key to exit without
resetting the Sequence Number.
4. Press the MODE key to return to the Weighing Mode.
6.7 Programming a Temporary Lot Number, Part Number or Part Name
The Lot Number, Part Number and Part Name of an Item Code can be changed temporarily from the weighing
mode without affecting the information stored in memory with that Item Code.
% QTY QTY % WEIGHT WT
Program Set Point 1 value with . . . target quantity low value target weight low value
Program Set Point 2 value with . . . % of quantity target value % of weight target value
Table 6-5. Setpoint Configuration
Setpoint Types % QTY QTY % WEIGHT WT
Setpoint 1 80 pieces (target) 50 pieces 2.0 lb (target) 1.2 lb
Setpoint 2 80% 75 pieces (target) 50% 1.5 lb (target)
Equation 80 x 80% = 64 N/A 2.0 x 50% = 1.0 N/A
Slow Beeping Occurs At 64 pieces 50 pieces 1.0 lb 1.2 lb
Rapid Beeping Occurs At 80 pieces 75 pieces 2.0 lb 1.5 lb
