Access to this menu requires that Analog Input Board calibration procedures be completed at the
factory for the respective channel. If calibration is not complete, a display message is presented to
first enter any missing required parameters.
c.
For a dual-channel system, first select the desired channel for which to conduct the procedure. The
number of any chosen active channel will be indicated in the upper-left corner of the display for the
remainder of this submenu.
d.
The user is prompted to select and enter the desired units for the limit Setpoints. If Setpoints were
previously entered, then those units will be presented as the default units. Units of Pound (lb),
Kilogram (kg), Gallon (gal), and Liter (ltr) are supported.
e.
If Factory Setup Mode is asserted, the decimal (unsigned integer) representation of the 16-bit DAC
calibration value [Range: 0 to 65,534] for calibrating the minimum output will be displayed.
•
AOB-mA board:
Adjust the DAC calibration value to yield a measured 4 mA loop output at
the output terminal block, or 2-pin header (P2), using a digital meter (three decimal places.)
If the current-loop is to be internally powered by the scale
, be sure to position the board’s
Loop
Power Slider-Switch
to
SCALE, which is when the text “SCALE” is visible beneath the slider.
•
AOB-V board:
Adjust the DAC calibration value to yield a measured 0 V output at the output
terminal block, or 2-pin header (P4), using a digital meter (three decimal places.) Be sure to
first select the voltage output range via the 2-pin jumper field.
f.
Enter the 4 mA (or 0 V) scale-measurement Setpoint in the previously-selected units. Any
previously entered Setpoint will be presented as the default value, unless a change of units was
detected in a previous step, in which case the Setpoint value will be reset to zero.
The value is always
positive in the range from zero through (Capacity Weight
–
1). The number of decimal points of the
displayed value represents the user-selection previously made in the
g.
If Factory Setup Mode is asserted, the decimal (unsigned integer) representation of the 16-bit DAC
calibration value [Range: (minimum output DAC calibration value + 1) to 65,535) for calibrating the
maximum output will be displayed.
•
AOB-mA board:
Adjust the DAC calibration value to yield a measured 20 mA loop output
at the output terminal block, or 2-pin header (P2), using a digital meter (three decimal places.)
If the current-
loop is internally energized, be sure to position the board’s
Loop Power Slider-
Switch
to SCALE, which is when the text “SCALE” is visible beneath the slider.
•
AOB-V board:
Adjust the DAC calibration value to yield a measured 5V/10V output at the
output terminal block, or 2-pin header (P4), using a digital meter (three decimal places.) Be
sure to first select the voltage output range via the 2-pin jumper field.
h.
Enter the 20 mA (or 5V/10V) scale-measurement Setpoint in the previously-selected units. Any
previously entered Setpoint will be presented as the default value, unless a change of units was
detected in a previous step, in which case the Setpoint value will be reset to zero. The value is always
positive in the range from (minimum Se 1) to the previously-entered Capacity Weight. In
this manner, the maximum Setpoint is forced to be greater than the minimum Setpoint. The
number of decimal points of the displayed value represents the user-selection previously made in
the
