4 TESTING
Before and after servicing an Pioneer PJX Series balance, an operational test and various
performance tests should be made to confirm if the balance meets specifications. Turn the balance on
and allow it to warm up for at least one hour before performing these tests. The Analytical models
need up to 4 hours to stabilize.
NOTE:
Make sure the test area is free from drafts and that the balance rests on a level and vibration-
free surface. The Analytical models especially need a solid platform, such as a stone table.

TEST MASSES REQUIRED
The masses required to test the Ohaus Pioneer PJX Series balances must meet the requirements
of the ASTM or OIML Tolerances listed in the table. Poor quality calibration masses can be the
cause of frustrating diagnostics.
