Section 1. Unpacking and Installation Unpacking Before unpacking your Doran scale, please read the instructions in this section. Your new scale is a durable industrial product, but it is also a sensitive weighing instrument. Normal care should be taken when handling and using this product. Improper handling or abuse can damage the scale and result in costly repairs that may not be covered by the warranty. If you notice any shipping damage, notify the shipper immediately.
Section 2. Scale Operation Fig. 1 DS100 Front Panel Display Functions The Model DS100 controls consist of GROSS/NET, TARE, ZERO (ON/OFF), UNITS and PRINT buttons located under to the LED display. The display is used to provide weight indications and operator messages describing scale operation. Power The DS100 is powered by an AC wall transformer. Turn the scale off by pressing and holding the ZERO (ON/OFF) button for three seconds. Turn the scale on by pressing the ZERO (ON/OFF) button.
Zero Weighing 1. Empty the scale base or place an empty container on the base and press ZERO to zero the scale. If the scale is in motion when the ZERO button is pressed, the DS100 will zero the scale once the scale becomes stable. 2. Place an item on the scale and wait for the MOTION indicator to go out 3. Read the weight on the display 4.
Section 3. Power and RS-232 Fig. 2 DS100 Rear Panel Power connections The DS100 is powered from a wall mounted transformer. The transformer has a power cord which plugs into the power jack located on the back of the scale. A strain relief is provided to the left of the power jack. The power cord can be looped around the strain relief to prevent accidental unplugging. RS-232 Connections The DS100 has a standard RS-232 output.
Section 4. Data Communications Introduction to data communications Basic understanding of serial data communications is needed when setting up the DS100 to communicate with a printer or PC. When setting up a serial communications system, there are two concerns which affect the configuration of that system. These are: • • Baud Rate Data Bits and Parity The baud rate determines how fast the data is sent from the scale. The sending and receiving units must be set to the same baud settings.

Section 6. Troubleshooting General Problem Resolution Problem Weight reading will not repeat or scale does not return to zero when weight is removed. What to Do or Check Make sure that the scale platter is not rubbing or touching the scale cover. Verify that there is nothing caught in the platform, under or around the load cell. Scale overloads early Verify scale calibration is correct. If problem persists, recalibrate the scale. Scale will not come to zero when the ZERO button is pressed.
Error Messages Error Message Er EP What to Do or Check The setup parameters loaded in nonvolatile memory have become corrupted. Verify scale parameters and calibrate. The A/D communication is not detected. Er Ad If problem persists, recalibrate. If problem still persists, the motherboard will need to be replaced. Verify load cell wiring connections. Ensure the load cell is wired properly.
Error Message gS-oL SPnL SPnH SPn E ERR 0 CAP E What to Do or Check The scale is in gross overload. The load exceeds the scale rating and might result in damage to the scale. Remove excess weight immediately. If problem persists, recalibrate. If problem still persists, the motherboard or load cell will need to be replaced. Raw counts for the span calibration is too low. Refer to the Calibration Troubleshooting section for raw count ranges. Raw counts for the span calibration is too high.
