7.6.1 Setting the Specifications for Scale 2
A scale connected to the Remote Scale Channel will be recognized by the DC-530 as Scale 2. The specifications
that need to be set to configure the communication with the second scale are as follows:
• SPEC 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.
• SPEC 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
• SPEC 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.
• SPEC 21, Bits 1 and 0 - Minimum Display (Scale 2) sets the display divisions displayed for Scale 2.
• SPEC 24 - Selection of Resolution of 2nd Scale (Scale 2) sets the display resolution for Scale 2.
• SPEC 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.
• SPEC 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.
• SPEC 30 - Set the Tare and Unit Weight Auto Clear conditions.
• SPEC 34 - Loadcell Sensitivities Selection mV/V (2nd Scale) sets the loadcell sensitivity range for
Scale 2.
• SPEC 35, Bit 2 - 2nd Scale Weight Unit sets whether the basic weight units for Scale 2 will be lbs or
kgs.
