(The decimal point position depends on the balance model.) Container 2 Place a sample on the pan or in the container. Sample 3 Wait for the stabilization indicator to turn on. Read the value.
6-2. Smart Range The smart range for the HR-251AZ / HR-251A consists of the standard range and precision range (high resolution). Smart range function The range switches automatically, depending on the value displayed. Pressing the RE-ZERO key allows weighing in the precision range, regardless of the tare value. The range can be fixed to the standard range by pressing the SAMPLE key. Precision Range And Standard Range For The HR-251AZ/HR-251A Unit Precision range Gram 0.0000 g to 62.0009 g Milligram 0.
6-3. Counting Mode (PCS) This is the mode to determine the number of objects in a sample based on the standard sample unit mass. The unit mass means the mass of one piece of the sample. The smaller the variables in each sample unit mass are, the more accurate the counting will be. The balance is equipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
For a more accurate counting operation, use samples with a unit mass of at least ten or more times the minimum weighing value of the balance. For example, when a balance with a mimimum weighing value of 0.0001 g is used, the recommended sample unit mass is 0.001 g or more. The sample unit mass stored, even if the AC adapter is removed, is maintained in non-volatile memory. Counting Operation 7 Place the samples to be counted on the pan.
6-4. Percent Mode (%) This is the mode to display the weight value in percentage compared to a 100% reference mass and is used for target weighing or checking the sample variable. Selecting The Percent Mode 1 Press the MODE key to select % (percent mode). Storing The 100% Reference Mass 2 Press the SAMPLE key to enter the 100% reference mass storing mode. Even in the storing mode, pressing the MODE key will switch to the next mode. 3 Place a container on the weighing pan, if necessary.
