Page 10: Operation
Operation Basic weighing function Purpose The basic weighing function can be used alone or in combination with an application program(counting, weighing in percent, etc.). Features  Taring the balance  Printing weights  Before using the balance at the first time, calibrate and adjust it at the place of use; For details, see “Calibration and Adjustment”...
Page 11 Operation Example Simple Weighing Settings: Application program: . (default setting) Step Key(or instruction) Display/Data output 1. Switch on the balance. ［］ Self-test is performed, followed by automatic initial tare function. 2. Place container on the balance (in this example,52 g). 3.
Page 12: Calibration And Adjustment
Operation Calibration and Adjustment Purpose Calibration is the determination of the difference between the weight result and the true weight(mass) of a sample. Calibration does not entail making any changes within the balance. Adjustment is the correction if any difference between the measured value display and the true weight(mass) of the sample, or the reduction of the difference to allowable level within the maximum permissible error limits.

Page 15: Counting
Application Programs Counting Menu code: . . Display symbol: pcs Purpose With the Counting program you can determine the number of parts that each have approximately equal weight. To do this, a known number of parts (the reference sample quantity) is weighed first, and the individual piece weight (reference weight) is calculated from this result.

Page 19: Density Determination
Application Programs Density Determination: Menu code: . . ) Purpose This application program lets you determine the density of solid substance using the buoy- ancy method. You can have results displayed with one decimal place, or no decimal places: see “Configuration.” Note: the sample holder and suspension wire used in the example below are not included with the balance/scale.
Page 20 Application Programs Example: Determining the density of a solid sample. Settings: Menu: Density determination (menu code: . . Accuracy of result: 1 decimal point (Code: Step Key (or instruction) Display/Data output 1.Switch on balance. ［］ 2.Attach sample holder to suspension wire 3.Tare the balance.
Page 21: Animal Weighing/Averaging
Application Programs Animal Weighing/Averaging(Menu code: . . ) Purpose weights of unstable samples (e.g., live animals) or to determine weights under unstable ambient conditions. With this program, the balance calculates the weight as the average of a defined number of individual weighing operations (also referred to as “subweighing operations"). Features ...
