METTLER TOLEDO PS Shipping Scale Technical/Operators Manual Basic Information The following sections describe some basic information that you will need to know as you install, calibrate, and use the PS in normal operating mode. The Display The PS’s display consists of six digits and five cursor positions. Each digit is composed of seven segments and is 12 mm high.
Chapter 2: Installation and Calibration Initial Calibration using GeoCal The functions for each key in normal operating mode are as follows: • UNITS—Press UNITS to switch between the selected main units and alternate units. • ZERO—Press ZERO to zero an empty scale. The reading must be within 2% of the calibrated zero. If the scale is in Sleep mode (as defined in the Sleep program block), press ZERO to “awaken” the scale.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual Initial Calibration using GEOCAL™ The PS shipping scale must be calibrated when the unit is initially installed to correct for local gravity variations thereby ensuring accurate weighing results. If the GEOCAL™ capabilities of your PS unit have been activated, the unit has been pre-calibrated from the factory.

Chapter 3: Configuring the Setup Parameters Configuring Setup Parameters 3 Configuring the Setup Parameters This chapter discusses basic information related to PS configuration and specific instructions on configuring each program block and operating parameter. Basic Setup Information The following sections describe some basic information that you will need to know as you configure the setup parameters for the PS.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual • Disconnect the power from the scale. Changes will not be saved. Configuring Setup Parameters This section describes the program blocks that govern normal operation including: • • • • • • • • Push Button Zero * Zero Cursor * Power-up Units * Build * Alternate Units Mode * Filter Baud • • • • • • • • ASCII Parity Stop Bits Protocol Sleep GEOCAL™* Calibration * End This is the order that they appear in the prompts.
Chapter 3: Configuring the Setup Parameters Configuring Setup Parameters Zero Cursor Program Block The Zero Cursor program block lets you enable or disable the center of zero indicator on the PS. (Metrology PCB jumper must be removed.) To configure the program block: 1. Press UNITS to display the 0 CurS prompt, then press ZERO. 2. Press ZERO to display the desired approval setting, enable or disable. 3. Press UNITS to accept the displayed option. The PS continues to the Power-up Unit program block.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual PS6L Power-up units = Pounds 149-ni 0-10 lb. x 0.1 oz, 10-70 lb. x 0.2 oz, 70-150 lb. x 0.5 oz * 150-n5 0-5 x 0.005 lb., 5-25 x 0.05, 25-150 x 0.1 lb.

Chapter 3: Configuring the Setup Parameters Configuring Setup Parameters Filter Program Block The Filter program block lets you configure the noise filter that is used in determining weight stability on the scale. The PS disregards environmental noise such as vibrations that affect the weighing accuracy according to the filter setting. To configure the program block: 1. Press UNITS to display the FiLtEr prompt, then press ZERO. 2. Press ZERO to display the desired noise filter.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual Parity Program Block The Parity program block lets you select the parity option for data transmission. Parity is an error checking mechanism. To configure the program block: 1. Press UNITS to display the PAr prompt, then press ZERO. 2. Press ZERO to display the desired parity option. Options include: • Space • Mark • Odd • Even • None 3. Press UNITS to accept the parity option. The PS continues to the Stop program block.

Appendix A: Host Interface Communication Parameters Appendix A: Host Interface The METTLER TOLEDO PS shipping scale can function as a peripheral device to a host computer. In host mode you can: • Calibrate the scale • Configure setup parameters • Request and receive weight data when the scale is in a stable state The scale does not reply to host weight commands if it is in calibration mode or if the scale cannot capture zero on power-up.

Appendix A: Host Interface Scale Status Byte Format ASCII CHAR. DEC HEX 76543210 ASCII CHAR.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual Toledo Protocol Host Commands Following is a listing of host commands and scale responses. Brackets “<>” are used to indicate that the characters within are a description of the transmitted data and are not part of the transmitted data string. indicates an ASCII Start Of Text character (HEX 02). indicates an ASCII Carriage Return (HEX 0D). Host Command Description W* Send normal resolution weight data. XXX.
Appendix A: Host Interface Scale Status Byte Format Scale Status Byte Format When communicating in host mode using the standard Toledo protocol, the PS may send status bytes containing information such as motion and over/undercapacity conditions. The message ? indicates transmission of a status byte. The status byte sent is an ASCII character that must be converted to binary form for decoding the bits.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual Status Byte Bit No. Bit Description 6 1 = New status data available. 0 = Host has read data. 5 Bit is always a 0. 4 1 = ROM test failed. 0 = ROM test passed. 3 1 = RAM test failed. 0 = RAM test passed. 2 Bit is always a 0. 1 1 = Calibration Required. 0 = Calibration Data OK 0 1 = EEPROM test failed 0 = EEPROM test passed. Calibrate Using Host Interface The PS shipping scale can be calibrated using the host interface.
Appendix A: Host Interface Scale Status Byte Format 6. Add the requested calibration weight to the scale, then send the command Y to continue. The scale responds CAL DONE or INCORRECT AMOUNT OF WEIGHT . Configure Scale Parameters Using Host Interface Configuration parameters can also be sent using the host interface. A command to send a new scale configuration over the host interface is available in the METTLER TOLEDO command set. To configure using the host interface: 1.
METTLER TOLEDO PS Shipping Scale Technical/Operators Manual The table below lists the programming options available in each program block as they are used in Host Interface Setup. When downloading the scale setup it is strongly recommended that you modify only the selections that you need to change in the current setup bytes sent by the scale. Leave the values of all other setup bytes as they were when sent from the scale (including the selections that are currently not used).
Appendix A: Host Interface Scale Status Byte Format You can obtain the current configuration by sending the S command. Then you can abort without changing by sending the A command to abort. Before sending the DONE reply, the configuration file is analyzed just as if it had been constructed using the keyboard. 3. Send the command desired new set of bytes to the scale: Y1Y2 ... Y19Y20 4. The scale will check to make sure the requested bytes are valid, then will echo the request: Y1Y2 ...
