Page 17: Linearity Calibration
Explorer Pro 3.3.3 Linearity Calibration Linearity calibration utilizes three calibration points, one at zero, center span and full span. This method minimizes deviation between actual and displayed weights within the balance's weighing range. Three weight values are used; zero, a weight value at midpoint of the balance's weighing range and a weight value at or near the specified capacity. -

Page 29: Check Weighing
Explorer Pro Check Weighing Check weighing mode permits you to weigh an item, set balance parmeters such as the nominal weight, over weight, under weight and assign a library name. This can then be recalled later eliminating the need to enter weighing parameters again. This type of weighing is where individual items must be checked against preset parameters. -
Page 30: Differential Weighing
Explorer Pro 3.10 Differential Weighing Differential weighing stores tare and weight values so a sample can be dried and the difference calculated at a later time. Up to 5 batches with up to 80 samples per batch can be stored. Samples can be added to the applications library. Batch and individual samples can be accommodated. - Page 31 Explorer Pro Procedure (Cont.) 3.10 Differential Weighing (Cont.)

Explorer Pro 3.14 Density (Cont.) 3.14.3 Improving the Accuracy of the Result of Solid Density Determinations The following tips should help you improve the accuracy of the results in the density determination of solids. Temperature Solids are generally so insensitive to temperature fluctuations that the corresponding density changes are of no consequence. However, as work is performed with an auxiliary liquid in the density determination of solids, their temperature must be taken into account as the temperature has a greater effect with liquids and causes density changes in the order of magnitude 0.1 to 1% per °C. -
Page 40: Library
Explorer Pro 3.15 Library The Explorer Pro Balance can store approximately 200 names in the library. Six functions in the balance have provisions for storing a library name, they are: Advanced Counting, Check Weighing, Differential Weighing, Formulation, Density and SQC.
