Page 4: Introduction
Introduction Introducing the Doran Scales, Inc. Model 4300 Digital Scale. This scale uses state of the art technology to provide you with a low cost solution to the most demanding weighing applications. With ease of use and setup in mind, the scale is simple to set up and ready to use. -
Page 5: Quick Start User's Guide
Quick Start User's Guide Fig. 1: Model 4300 Front Panel Layout INSTALLATION: The desired scale location should be flat, level and free of any obstructions, which might interfere with the operation of the scale platter. Remove the platter and locate the bubble level inside the base. Adjust the four scale feet so the bubble is centered and the platform is stable so it does not rock. -
Page 6: Model 4300
The 4300 is equipped with an optional "Zero on Demand" feature which holds "zero" requests until motion stops. This option may be activated during the scale setup procedure. Refer to the Parameter Setup section or your authorized Doran Scales dealer for details. UNITS button: The UNITS button allows the operator to change the scale units by pressing a button. -
Page 7: Print
The 4300 also has several automatic print options which may be used to simplify printer operation. These options may be activated during the scale setup procedure. Refer to the Parameter Setup section or your authorized Doran Scales dealer for details. OVER / UNDER button: The over and under buttons are used to enter the weight values needed for checkweighing applications. -

(If checkweighing to zero, place the target weight on the scale.) 2) Press ZERO to zero the scale. The weight indication should now be zero. 3) Place an item on scale platter and wait for the motion (MOT) indicator to turn off, indicating a stable weight. -

Press and release UNITS until "CAP 50"... -
Page 12: Calibration
Scales calibrated at 10% of capacity are more likely to have significant errors at full capacity than are scales calibrated at 25% or 50%. Doran Scales recommends that all scales be calibrated at full capacity whenever possible. 10% calibration should not be used when calibrating scales for legal for trade applications. -
Page 13: Analog Setup
Analog Setup: NOTE: Use this section only if you are curious about the load cell output. On scales with factory installed platforms, the zero and span will lie within permissible limits. There are no jumpers, pots, or switches to adjust. Raw counts are used to verify if a load cell will operate within specified limits. -
Page 14: Detailed Parameter Setup
Detailed Parameter Setup The Model 4300 has 26 setup and calibration parameters, which can be accessed through two setup modes. The Configuration mode will allow the user to change the scale configuration without accessing the scale calibration parameters or breaking the Weights and Measure seal. -
Page 15: Stepping Through The Menu Parameters
Stepping Through the Menu Parameters: Once the Calibration Setup Menu has been entered, you may step through the menus by pressing and releasing UNITS. A different display prompt will appear for each parameter in the menu. The parameter list on the following pages corresponds to the parameters available in the Calibration Setup Menu. -

Page 26: Data Communications
Data Communications Introduction to Data Communications: In the Model 4300 data is sent to a printer or computer by using "asynchronous serial data communications." Data is broken up and sent one piece at a time to the printer or computer. In spite of this apparent simplicity, a basic understanding of serial data communications is needed when setting up the scale. -
Page 27: Rs485
stop bit signals the end of the data and permits the bit timer a chance to reset itself before the next data byte is sent. No parity bits are sent. In many cases, the receiving unit is a slow printer with limited memory. In these cases, more data may be sent than the printer can use. -
Page 28: Printer Modes
NOTE: When installing a 4300 on a RS485 system, it may be necessary to use termination resistors. The 4300 has three termination resistors built in the main board. Consult your authorized Doran Scales dealer or the factory for more details. -
Page 29: Data Output Format
Data Output Format: In order for the serial data sent from the scale to be useful, the data must be organized so that it is easy to read. To accomplish this, the scale arranges the displayed data with additional text to indicate the active units and to indicate the presence of motion during the reading. - Page 30 Command Scale output Response (TXD) Description (RXD) <STX><xxxx.xx><SP><uu><SP><MOT><LF><CR> “_ ” standard format, Prints current weight (hex 57) and units. <STX><xxxx.xx><SP><uu><SP><AUO><SP><MOT><L “_ ” enhanced format, Prints current weight F><CR> and units with Accept, Under, Over status. “_ ” dual print format, Prints current and kg <STX><xxxx.xx><SP><uu><SP><MOT><LF><CR>...
