  Inside Limits and Outside Limits - Selections of no sound, one beep, two 
beeps or three beeps may be programmed to have the instrument indicate 
when the weight of the sample is inside or outside the sample weight tolerance. 
 
Tare Options 
Two tare options define how stable the 
balance must be before a test will 
start.  The third tare option is labeled 
Special Options and is used to tare a 
syringe, foil tray or other lightweight 
device used to carry or hold the 
sample on the pan. 
  Pan Tare 
– Records the 
average empty pan weight after 
ensuring that its weight is sufficiently stable over a programmable period of 
time.  Taring continues until the weight is found stable (
≤ 0.2mg deviation) over 
the programmable period of time.  Temperature fluctuations occur in the test 
chamber, dependent on a number of different criteria such as previous test 
temperature, the amount of cool down time between tests, and the current idle 
temperature.  The temperature fluctuations cause the balance readings to drift 
during taring and are reflected as an error in the final value.  Because the 
conditions that cause the temperature fluctuations are not always constant, the 
error often appears as a higher standard deviation for a series of tests on a 
particular sample. 
The Pan Tare option has four (4) user selections to adjust the relationship 
between tare time and tare error to improve overall operation for a given 
product or purpose.  The following table summarizes the menu choices and the 
parameters associated with each choice.

The ULTRA-LOW MOISTURE option should be used for samples with 
moisture/solids/ash content between 0.005 and 0.2 percent.  This option may 
be used to improve accuracy for samples with moisture content in excess of 0.2 
percent but will increase the overall testing time.
