7.4.1 Setting the Specifications for Scale 2
A scale connected to the Remote Scale Channel will be recognized by the DC-788 as Scale 2. The specifications
that need to be set to configure the communication with the second scale are as follows:
• SPC 26. Bit 1 - 2nd Scale sets whether or not the Remote Scale Channel is enabled. Please note that
the scale switch is not activated until the 2nd scale has been calibrated.
• SPC 35, Bit 2 - 2nd Scale Weight Unit sets whether the basic weight units for Scale 2 will be lbs or
kgs.
• SPC 21, Bits 1 and 0 - Minimum Display (Scale 2) sets the display divisions displayed for Scale 2.
• SPC 24 - Selection of Resolution of 2nd Scale (Scale 2) sets the display resolution for Scale 2.
• SPC 25, Bits 2 through 0 - Weight Decimal Point Position of 2nd Scale (Scale 2) sets which digit the
decimal point appears after in the Weight display.
• SPC 34 - Loadcell Sensitivities Selection mV/V (2nd Scale) sets the loadcell sensitivity range for
Scale 2.
• SPC 30 - Set the Tare and Unit Weight Auto Clear conditions.
• SPC 14, Bit 3 - Clear Unit Weight When Swap Scale sets whether the Unit Weight is cleared
automatically when the SCALE key is pressed to move from weighing on one scale to weighing on
the other.
• SPC 14, Bit 2 - Rezero When Swap Scale sets whether the scale is rezeroed automatically when the
SCALE key is pressed to move from weighing on one scale to weighing on the other
• SPC 14, Bit 1 - Auto Scale Switching sets whether or not a Unit Weight established on the built-in
platform is automatically transferred to Scale 2. When Auto Scale Switching is enabled, the scale
also automatically switches to Scale 2 once a stable unit weight is calculated.
