Page 4: Introduction
With ease of use and setup in mind, the scale is simple to set up and ready to use. The Model 300 offers many features. A few of these features are listed below: NTEP certification for Class III installations to 5,000d. -
Page 5: Quick Start User's Guide
Quick Start User's Guide Fig. 1: Model 300 Front Panel Layout Power Up: Connect the Model 300 to a compatible power source. Or, press and release ZERO to turn on, for scale with battery option. Basic Weighing Operation: 1) Remove all items from the scale platter. -
Page 6: Zero
The Model 300 can be used while recharging the battery. A full recharge takes place in four hours, whether the scale is on or off, in fact the Model 300 can be used with the AC charger cord plugged in on a continuous basis. -
Page 7: Low Battery Indication: (Optional)
Be sure the AC power is not excessively noisy - this can occur if large inductive loads, such as solenoids or motors, are on the same power line. The Model 300 has a filtered power supply to reduce the effects of normal line noise, but they cannot limit severe fluctuations. -
Page 8: Quick Setup Guide
Quick Setup Guide Load Cell and Power Connections: Load cell connections are made through a terminal block located at the bottom center of the main PC. Board (Fig. 2). The power cord connects to a connector adjacent to the transformer. These connections are accessible by removing the scale platter and access cover. -

Page 10: Analog Setup
NOTE: 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 11: Detailed Parameter Setup
Detailed Parameter Setup The Model 300 has 20 setup and calibration parameters, which can be accessed through the scale's Calibration Setup Menu. Entering and Exiting the Calibration Setup Menu: To enter the Calibration Setup Menu. Remove the two screws mounting access cover. -

Page 22: Data Communications
Data Communications Introduction to data communications: In the Model 300 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 23: Printer Modes
"Ctrl-Q" is received. To use this mode, the RTX line of the scale is tied to the TXD line of the receiving unit. Printer Modes: The Model 300 offers four different print control modes. These modes dictate when printer data is sent. Transmit on demand (tod): In this mode, scale data is transmitted whenever the print button is pressed, the remote print button is pressed, or a print request is received from the serial port. -
Page 24: 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. -
