- Page 4 The PX balance is a precision weighing instrument that will provide you with years of service if properly cared for. PX balances are available in capacities from 82 grams to 8200 grams. 2-line backlit display, with 6 weighing applications and many other features. Safety notes are marked with signal words and warning symbols.
- Page 5 Carefully remove your PX balance and each of its components from the package. The included components vary depending on the balance model (see the list below). Save the packaging to ensure safe storage and transport. Please read the manual completely before installing and using the PX balance to avoid incorrect operation. Components included: Balance Power adapter + Attaching plug...
- Page 6 Connect the DC output connector to the power receptacle on the rear of the balance. Then connect the AC adapter plug to a suitable electrical outlet. It is suggested that the balance should not be used until it has been connected to power and acclimatised to the environment for a certain period of time.

- Page 11 Improving counting accuracy by re-calculating the piece weight automatically as parts are added. APW Optimization occurs only when the number of pieces added to the pan is between one and three times the number already on the pan. Changing printing setup. See Section 7 for more information. Before using any application, be sure the balance has been leveled and calibrated.

- Page 13 4. Confirm the weighing time by pressing , and the message "Ready" will display at the lower left of the screen. 5. Place the dynamic object on the pan. The balance begins a countdown (averaging process). During the countdown, the screen shows the time remaining. 6.
- Page 14 When making density measurements, the material should weigh at least 10.0 mg on an analytical balance and 100 mg on a precision balance. Balance Preparation with Ohaus Density Kit (Optional) Allow the balance to warm up sufficiently before making measurements.
- Page 15 Place the Support into position over the bracket making sure the Support does not make contact with the Bracket as shown in illustration. Install beaker on support as shown. NOTE: Beaker and thermometer are not supplied as part of the density kit. The density Q is the quotient of the mass m and the volume V.
- Page 16 Place the solid in the Weighing Pan on the Weigh Below Hook in the liquid as shown. Ensure that there are no air bubbles on the solid to be weighed. Close the draft shield doors and weigh the solid (buoyancy P). The display indicates the density in grams/cc. For density determination of solids with a density less than 1 g/CM , the bottom of the Weigh Below Hook for solids must be used as it holds the solid body below the surface of the auxiliary liquid.
- Page 17 In DENSITY SETUP, set Mode to Liquid Density and enter sinker volume in cc’s. After weighing the sinker in air and then weighing the sinker immersed in liquid, the balance calculates the density of the liquid and is displayed in grams/cc. See illustrations below for placement of the sinker. When the sinker is immersed in the liquid, it must not come into contact with the bottom of the beaker.
- Page 18 Press and hold the button until Density appears. Press to initiate the Density Determination. Sample type: Solid Auxiliary Liquid: Water Porous Material: Off Water Temperature: Measure the actual water temperature using a precision thermometer. The water temperature is 20.0 by default. Press to increase or decrease the value of temperature.
- Page 19 3. Press the button to get the density of the sample. After completion of the test, press the button to test a new sample. Press and hold the button until Density appears. Press to enter the Density Determination. In determining density with the balance, the balance setup and density determination procedures are basically the same for a floating solid and a non-floating solid except for the necessary holder (as shown in the figure)
- Page 20 Sample type: Solid Auxiliary Liquid: Other Porous Material: Off The default value of the auxiliary liquid is 1.00000 g/cm Press to increase or decrease the value in accordance with the actual density of the auxiliary liquid. See Section 4.5.1 and Section 4.5.2 for the specific procedures for density determination.
- Page 21 Sample Type: Liquid Volume: The calibrated sinker has a default volume of 10.0 ml, which can be increased or decreased by pressing After setting the volume, press to begin the weighing. when the Density Type is set to Liquid, the Liquid type and Porous material selections are disabled.
- Page 22 Press and hold the button until Density appears. Press to enter the Density Determination. Sample type: Solid Auxiliary Liquid: Water Porous Material: On Set the following parameters by pressing Water Temperature Weight Oil Density Measure the actual water temperature using a precision thermometer.
- Page 23 3. Weigh the oiled sample in the liquid with the balance and the density determination kit. 4. When the * (symbol of stability) appears, press the button to confirm the weight of the oiled sample in the liquid. The density of the sample is displayed. 5.
- Page 24 Ensure the balance has been leveled and calibrated. The PX balance is equipped with a weigh below hook for weighing below the balance (as shown in the figure below). Before turning the balance over, remove the pan and draft shield elements (if present) to prevent damage. Do not place the balance on the pan support cone or load cell pins.

- Page 26 ExCal models only have Span Calibration and Linearity Calibration. Calibration is accomplished with the internal calibration mass. Internal Calibration can be performed at any time, provided the balance has warmed up to operating temperature and is level. With the Balance turned ON and no load on the pan, the internal calibration can be performed. Alternatively, press the button and select Internal Cal to initiate the internal calibration.
- Page 27 2. Press to enter the Calibration Menu. To change the calibration mode, press until Span Cal (span calibration) is displayed. 3. Press to begin the span calibration. 4. The calibration masses value will be shown in the screen. After the display shows "Place weights" and "100.000 g", place weight(s) of 100 g on the pan for calibration.
- Page 28 Continue to follow the instructions on the display until the calibration is completed. 1. Press and hold the button, and the Calibration Menu will display. 2. Press to enter the Calibration Menu. To change the calibration mode, press o until Linearity Cal (linearity calibration) is displayed.
- Page 29 6. Once the linearity calibration is completed successfully, "Linearity done" will display. Press any button to return to the previous screen. Enter this sub-menu to customize balance functionality. The factory default settings are shown below in bold. Set the language displayed for menus and displayed messages.
- Page 30 Set the displayed readability of the balance. 10 Divisions = readability is increased by a factor of 10. For example, if the standard readability is 0.01g, selecting 10 Divisions will result in a displayed reading of 0.1 g. Set the current date format. YYYY/MM/DD DD/MM/YYYY Set the date in the current date format.

- Page 37 When the balance is used in trade or a legally controlled application it must be set up, verified and sealed in accordance with local weights and measures regulations. It is the responsibility of the purchaser to ensure that all pertinent legal requirements are met. Before the verification and sealing perform the following steps: 1.
- Page 38 Use RS232 Interface Commands (Section 9.6.1) to control the balance from a PC. The Serial Port Data Collection / SPDC software is provided by Ohaus and can be used on operating systems that do not have the HyperTerminal software mentioned above. SPDC software can preliminarily collect and transfer the data to Microsoft files (such as Excel, Word, etc.).
