PT300 Users Manual Rev E, April 1999 Operations Diagram 1: PT 300 Keypad and Display Turns the scale on. The scale will test itself by activating all of the segments on the display and then zero itself. Occasionally the display will show EEEE0, this means that the scale is seeking zero.
PT300 Users Manual Rev E, April 1999 TEST/ZERO This switch will "test" the display by activating all of its segments. It then zeros the scale. See the explanation for the ON button. LAMP This switch will back light the display for night use. The lamps only stay on while the button is being pushed.
PT300 Users Manual Rev E, April 1999 Batteries / Charging This scale can be used while it is charging. Batteries: 6 - 1.2 volt nicads. Battery Life: Approximately 5 years. (1000 charge/discharge cycles). Battery duration between charges: Approximately 8 hours of continuous use before the low battery indicator comes on, and approximately 2 hours after that before the scale shuts itself off.
PT300 Users Manual Rev E, April 1999 Totalizing and/or Printing Before you attempt to do either of these, a few terms and definitions must be understood. These terms only apply to scales that are cabled together. Master Scale: If more than one scale is being used, the first scale in line is referred to as the Master Scale.
Data Interface Serial ASCII 20 mA current loop, active or passive. (The PT300 supplies the current for active current loop, and an external current is used for passive current loop. Passive is preferred for longer battery use between charges.)
PT300 Users Manual Rev E, April 1999 Error Messages Overload. Reduce load to scale. Underload. Re-zero scale. Seeking zero. Wait until reading is displayed. If this error EEEE0 message stays on, the EEPROM may be damaged. Scale will require calibration.
PT300 Users Manual Rev E, April 1999 Cables The following diagrams show the different types of cables that can be used with PT 300 scales. Cables can be ordered consisting of 2-6 connectors so you can match the number of scales your system has. The following diagrams illustrate a 4 scale system.
