DORAN MODEL 8000 OPERATING AND SERVICE MANUAL If you have sufficient time to recharge frequently and use the scale often, you may select longer on-times or continuous-on. If you use the scale briefly or infrequently, shorter on- times are more desirable for longer battery life. The ON/RESTART button will always act as an on/off control. When the unit is off, the ON/RESTART turns the scale on for the specified period of time.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL The CONV button changes the weight display unit. This is necessary in applications where there is a need to read equivalent weights in different units. The PRINT button tells the 8000 to transmit weight data from its data interface to a printer, computer or other peripheral device. The 8000 provides the capability of enabling or disabling either of these functions.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL When the d.b.P parameter is selected, press the Print pushbutton to toggle the hSh function on and off. "Clear To Send" is a signal used by some serial communications devices such as printers to control data flow. 3.4.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL 3.4.15 Motion Aperture (MA) Function MA Option 1 3 5 Description 1 division of change before motion 3 divisions of change before motion 5 divisions of change before motion The Motion Aperture is used to select how many displayed divisions of motion must be sensed before the unit will go into a motion state. If a "Legal for Trade" mode is selected, the scale will default to 1 division for the motion aperture. 3.4.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL 4.2.2 Status Annunciators lb -Weight display is in pounds. kg -Weight display is in kilograms or grams. oz -Weight display is in ounces. lb & oz -Simultaneous "lb" and "oz" annunciators indicate weight displayed in pounds and ounces. NEG -Indicates negative weights in the "lb & oz" weight display mode only. MOT -Motion indication(weight is changing). ZERO -Indicates "Center of Zero" (scale is within +/- 1/4 div of displayed zero).
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL 3) Scale activity occurs - indicated by the "MOT" LED. The On-Timer is reset and the scale stays on for another delay period. 4.3.2 ZERO Function The ZERO pushbutton is active as a zero function in the GROSS weight mode only; it is inactive in the NET mode. When pressed, the ZERO causes the display to read zero. It operates on positive or negative gross weights.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL 4.3.4 CONV Function Pressing the CONV button causes the 8000 to change the current weight display unit each time it is pressed. In the "Std" mode, the weight will convert from "lb" to "kg" to "oz", and also to "lb & oz" when the scale is set to one of the capacities listed in Section 3.4.5.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL 4.5 LOW BATTERY INDICATION The "BATT" annunciator will flash to indicate that the battery needs recharging. Once "BATT" begins flashing, there will be approximately four more hours of battery life before the scale shuts down. The 8000 remains accurate and useable even with "BATT" flashing. 4.6 OVERLOADS Placing loads greater than the scale's capacity on the platform causes the 8000 to display an overload message.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL The scale will transmit stable weights above gross zero once for each transition from Start-Up Gross Zero to the stable weight. When an object is placed on the platform and the scale stabilizes at the weight, the scale will transmit the weight data and then disable the output. The output will remain disabled until the object is removed. Once the scale returns to Start-Up Gross Zero, the data output is enabled to transmit the next stable, nonzero weight.

DORAN MODEL 8000 OPERATING AND SERVICE MANUAL Note: 1 = switch closed (on), 0 = switch open (off) 6.3.3 Analog Zero Setting The zero calibration establishes the load cell output with no load on the scale platform. The zero offset switches can be set in any combination to obtain the desired offset using the offset chart as a reference. The zero offset should be adjusted to obtain a reading between -10000 and-15000 for an accurate zero calibration and maximized span calibration.
DORAN MODEL 8000 OPERATING AND SERVICE MANUAL Span should be adjusted to obtain a net change of approximately 18000 at dead load to 30000 internal counts at full capacity load by adjusting the span switches for the load cell output. 6.5 DIGITAL CALIBRATION Digital calibration is used to calibrate the scale indicator to the weight placed on the platform and retain that data after the indicator is shut off. 6.5.1 Digital Zero Calibration To perform a digital zero calibration: 1.
