SCIENTECH® Series 12000 Electronic Balance Setup and Operating Procedures PN11756C
Thank you for choosing a Scientech Electronic Balance. Scientech, an ISO9001 registered company, and its employees are pleased to provide you with a balance designed and manufactured for years of reliable service and proudly made in the U.S.A. The attractive quality of Scientech balances has been demonstrated by being certified to carry the “CE” mark of conformity. Please read this manual completely before using your balance.

Choose the Proper Environment: The environment in which your balance is used is very important. Air movement, temperature changes, vibrations, direct sunlight, etc. influences the performance of high precision balances. Therefore, place your balance on a solid, sturdy surface that is free of air currents and vibration and not in direct sunlight. The surface should not be magnetic and should be located away from doors, windows, heaters, air conditioners and fans.
Connect to an Electrical Outlet: The balance is supplied with a 115/220, 50/60 Hz automatic switching, remote power supply. This power supply will work with most electrical outlets, however, before making any connections, verify that the power (VAC) requirement shown on the remote power supply is compatible with the AC power outlet to which the balance will be connected. Note: Note: Note: First plug the round DIN connector into the balance’s rear panel receptacle.
Environment: 1. 2. 3. 4. 5. The more stable your environment, the better your measurement results. Changes in temperature, pressure, and humidity affect balance performance and weight stability. Ideal room conditions are 20º C with a relative humidity between 45% and 60%. Fluctuations in temperature should not exceed 1º C per hour. Humidity fluctuations should not exceed 10% per hour. Balances should not be placed in close proximity to anything that shakes, vibrates, or stirs violently.
The RANGE/FUNCTION Button: Single Range Balance Models: Pressing the RANGE/FUNCTION button begins the following menus cycle: • PCS – Front panel parts counting • HI OK LO – Checkweighing • CAL 1 – Autocalibration • CAL 2 – Linearity • • T – Live animal weighing % - percent weighing To select the desired function, press the MODE button when it appears on the display. Note: Front panel parts counting is not available with bi-directional RS-232 enabled.
Balance Functions and Features: Autocalibration – To Calibrate the balance to an External Weight: This procedure calibrates your balance to an external calibration weight. If your balance has a motorized internal calibration weight (9000-INT), please use the procedure for Autocalibration Using 9000-INT Motorized Internal Calibration Weight. Note: Note: Note: Note: Dual range models must be placed in HI range before starting the calibration procedure.
Autocalibration – To Calibrate the Balance and its Motorized Internal Calibration Weight to an External Weight: This procedure is only for SA and SM balances with the suffix IW after the model number, which means a motorized internal calibration weight is installed. This procedure first calibrates the balance to an external calibration weight then recalibrates the internal calibration weight to the external weight.
(PCS) Front Panel Parts Counting: Note: 1 2 3 4 5 6 7 8 Access to the PCS function via the front panel is disallowed if bi-directional RS-232 is enabled. RS-232 is enabled by selecting local control (LC) oFF (see RS-232 Front Panel Configuration section for details). Local control ON means the front panel controls the balance. User Action Press the FUNCTION button (or MODE and RANGE buttons simultaneously for dual range models). Press the MODE button when PCS appears on the display.
(%) Percent Weighing: 1 2 3 4 5 User Action Place an empty container on the weighing pan and press the ZERO button. Place the sample which represents 100% in the weighing container. Press the FUNCTION button (or MODE and RANGE buttons simultaneously for dual range models). Press the MODE button when CAL 100 appears on the display. If you want to exit the percent weighing mode, press the MODE button. Balance Response Zeros are displayed.
Capacity Tracker: The capacity tracker provides a graphic display of the used and unused portions of the weighing range and is shown in Figures 4 and 5. Each segment represents 10% of the balance's total capacity. As 10% of the balance’s capacity is used the first segment will illuminate. As 20% of the balance’s capacity is reached the second segment will light and so on.
Below Balance Weighing: Note: Please use care when installing Below Balance Weighing. The suspension can be damaged if over tightened. The overload protection which is built into the pan assembly is not available at the below balance hanging device. Therefore, care must be taken to avoid side shocks or pulling too hard on the hanging device. For applications requiring suspension of weighings below the balance, a 6-32 threaded screw is provided. To access the set screw, proceed as shown.
RS-232 Interface: Note: Scientech balances are DTE (computer) devices. If communicating to another DTE device (ie computer), a Scientech RS-232 cable, PN10697, or normal null modem cable is required. If you are communicating to a DCE device (printer), a serial cable is required. Scientech offers a serial cable, PN11367, for your convenience. Your balance is equipped with a bi-directional RS-232 compatible interface. The interface is uni-directional (balance send only) when the local control is set to ON.
User Action PROTOCOL or HANDSHAKE SELECTION (Pr on is default). 5 6 7 8 9 10 11 Balance Response Press the MODE button. The current software protocol setting, Pr oFF or Pr on and OK are displayed. Press the SEND button to choose between on or off. Then press the ZERO button. PARITY SELECTION (PA nonE is default). SAVEd OK is displayed followed by the chosen setting and OK. Press the MODE button. The current parity setting, PA EVEn, PA odd, or PA nonE and OK are displayed.
Bi-Directional RS-232 Command Set: The following commands can be sent to the balance in any combination of upper and lower case characters. No action is taken by the balance until it receives a carriage return indicating the end of the command string.
Command [decimal number]_PCT[CR] Response None [Decimal number]_ENTER_[integer] _PIECES[CR] None [register number]_RCL_[(CONVERT) (CAL) (PIECES)][CR] TAVG[CR] RESET_TAVG[CR] REG XXX :[register contents][MULT.
Type 3 Commands – Balance Output Functions: Command SEND[CR] [register number]_RCL[CR] Response See the RS-232 Balance Message Formats section. REG XXX:[register contents][current units or 'MULT.'] [CR] [LF] RCL_TARE[CR] REG 091:[TARE register contents] [current units][CR][LR] REG XXX:[contents of specified register][MULT.
RS-232 Balance Message Formats: The balance will respond to a SEND command by transmitting a message in one of three formats depending on how the SEND command was issued. The following discussion defines four types of SEND commands and the three message formats. 1. 2. 3. 4. The first case typically applies to a balance with RS-232 connected to a printer and an external print switch.

Troubleshooting Guide: Note: Many problems such as the balance remaining in the turn on sequence, "weird" characters on the display or "garbage" on the display are caused by connecting the power supply to the balance incorrectly. The proper procedure is to connect the round DIN connector on the power supply cable to the balance then plug the power supply into the wall outlet.
