rechargeable battery and with a smaller cabinet.
Note: When TI-1200 is shipped as a part of a complete Scale e.g. AV-250-seies and AL-100-21, the Scales are normally
calibrated. When TI-1200 is shipped together with Loadcells it is adjusted to the application but a calibration is always needed at
the place of installation.

    TI-1200 Digital Indicator is a general purpose, industrial grade weight indicator. TI-1200 comes with an internal 6V rechargeable battery, are capable of driving four 350 ohm load cells and operate identically. All readout up to 50,000 display divisions on a liquid crystal display (LCD) with back light. All set up parameters may be entered via the front panel keys, including calibration.

  • Page 5 CONNECTING THE SERIAL PRINTER, REMOTE DISPLAY OR COMPUTER The TI-1200 indicator comes standard with one full duplex RS-232 serial port, designed for connection to either a PC or a serial printer. The same port may be also used as a simplex, RS-232 port designed for connection to a remote display.

  • Page 6: Configuration

    CONFIGURATION OVERVIEW The indicator contains two main setup menus: The Setup (“F”) menu which configures the indicator to your weigh platform and the User (“A”) menu which configures the serial communication port and enables some user options. The Setup and User menus consist of several menu selections, each with its own sub-menu of choices.

Value should be consistent with legal 1,000 1,500 2,000 2,500 3,000 4,000 5,000 Graduations requirements and environmental limits on the useful system resolution. 6,000 8,000 10,000 12,000...
  • Page 8 DETERMINING PROPER SPAN GAIN (F2) Note: Normally done from factory. OVERVIEW The Span Gain parameter found in F2 of the Setup Menu is directly related to the ADC (Analog to Digital Converter) integration time. This means that the lower the setting, the higher the number of measurements per second. A span gain setting of 25 produces about 25 to 30 measurements per second, while a span gain of 200 produces only about 3 or 4 measurements per second.
  • Page 9 USER (“A”) MENU ENTERING THE USER MENU 1. Enter the Setup (“F”) menu by following the directions above. 2. Use the right or left directional keys shown in Figure 3-3 to move right or left in the Setup (“F”) menu until the indicator shows ” A 1”. NAVIGATING IN THE USER MENU 1.

  • Page 11: Calibration

    CALIBRATION The indicator is calibrated by following the procedures embedded in F16 (Zero) and F17 (Span) of the Setup Menu. Each procedure enters a value into the indicator's non-volatile memory - F16 the zero value (deadweight) and F17 the span value (test weight). The minimum test weight that can be used is 1% of full-scale capacity.
  • Page 12 KEY-IN ZERO CALIBRATION VALUE (F19) Note: This procedure is intended for emergency use only in the case of non-volatile memory loss. A valid zero calibration value, obtained from a successful F16 calibration procedure, must be used. 1. While in the Setup mode, scroll to "F 19", then scroll down once using the ZERO key. 2.

  • Page 14: Serial Port Information

    SERIAL PORT INFORMATION FULL DUPLEX MODE The Full Duplex Mode provides a Demand serial transmission mode and is selected by setting A3 to “d” and A6 to “0”. The Demand mode allows control from a host device, usually a PC, and can be activated by pressing the PRINT key on the indicator’s front panel. Figure B-1 shows a suggested cable diagram for interface to a PC.
  • Page 15 PRINT TICKET MODE The Print Ticket Mode is designed specifically for a serial printer and is selected by setting A6 to “1”. Figure B-3 shows the fixed format of the print ticket. For printers with limited buffers, this mode supports DTR pin handshaking. The DTR pin from the serial printer is wired to the indicator’s RXD pin which then functions as a CTS pin.

  • Page 16: Fault Localization

    DISPLAYED ERROR CODES CODE MODE MEANING / POSSIBLE SOLUTION Normal Gross Overload. A weight greater than the rated capacity has been applied to Operating Mode the scale. Remove the weight from the platter or try re-calibrating the scale. Otherwise, check for a bad load cell connection or possible load cell damage due to overloading.

  • Page 17: Operation

    OPERATION LCD Annunciator MEANING Better known as the “Center of Zero” annunciator, this light is active whenever the displayed weight is within ± 0.25 divisions of true zero. Indicates that the indicator is displaying net weight. Indicates that the indicator is displaying gross weight. Indicates that a tare weight has been established in the system.
  • Page 18 KEYBOARD The keyboard is composed of five function keys. FUNCTION KEYS lb/kg – This key toggles the indicator between lb and kg units if enabled in the User (“A”) Menu Zero - This key sets the indicator to display zero provided the following conditions are met: 1.
