12.11 GLP autotest
AUTOTEST function is designed to aid a user in assessing balance’s operation and
diagnosing the reasons for occurrence of errors in weighing which exceed the
maximum permissible values for a given balance model.
By means of a simple, repeatable and fully documented way the function enables
optimizing balance’s settings to maintain the best possible repeatability and
weighing time at workstation. The main purpose of the function is the possibility of
monitoring the above-mentioned parameters at optional moment and saving
records from the carried out tests in the form of printed reports of the tests that are
automatically generated at the end of examination.
The test controls repeatability of placing the interval weight and determining error of
indication with reference to balance’s maximum capacity.
Testing procedure:
• two times loading of the internal weight, followed by 10 times loading of
the internal weight
• balance internal adjustment
• calculating the value of standard deviation
• report printout
Test results:
*Deviation for Max.
*Value of repeatability of indication expressed as standard deviation
