Cal Adjust (Not Applicable To Excal Models); Span Calibration - OHAUS PJX Serie Bedienungsanleitung

EN-20
With the Balance turned ON and no load on the pan, press the Tare / Menu-Cal button and select InCal to initiate
the internal calibration.
The screen shows the status, and then press any button to return to the current application after calibration.
5.2.3 Cal Adjust (not applicable to ExCal models
Use this calibration method to fine tune the effect of the Internal Calibration.
Calibration Adjust may be used to adjust the result of the Internal Calibration by +100 divisions.
Note: Before making a calibration adjustment, perform an Internal Calibration. To verify whether an adjustment is
needed, place a test mass equal to the span calibration value on the pan and note the difference (in divisions)
between the nominal mass value and the actual balance reading. If the difference is within +/- division, calibration
adjustment is not required. If the difference exceeds +/-1 division, calibration adjustment is recommended.
Example:
To perform a Calibration Adjustment, select InCal Adjustment from the list of Calibration Menu; enter the value
(positive or negative divisions) to match the difference noted earlier in the procedure.
Recalibrate using Internal Calibration. After calibration, place the test mass on the pan and verify that the mass
value now matches the displayed value. If not, repeat the procedure until Internal Calibration reading agrees with
the test mass.

5.2.4 Span Calibration

Span calibration uses two calibration points, one at zero load and the other at specified full load (span). For
detailed calibration mass information please refer to the specification tables in the "Span Calibration Points",
SPECIFICATIONS, Section 9.
With the balance turned On and no load on the pan, Span Calibration can be performed. The best accuracy is
achieved using the mass closest to the full span value.
Steps for span calibration
1. Press and hold the Tare / Menu-Cal button, and the
Calibration Menu will display.
2. Press Yes to enter the Calibration Menu.
