Adjustment; Adjusting - KERN MLB50-3 Operating Instructions Manual

6.5 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordinated – in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location (
only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out during the initial start-up, after change in lo-
cation and variation of surrounding temperature. It is also recommendable to adjust
the balance periodically during weighing operation in order to obtain exact measured
values.

6.6 Adjusting

Using a precision weight, the accuracy of the balance can be checked at any time
and adjusted.
Method of approach when adjusting:
Ensure sound ambient conditions.
Use the main switch (above the power plug) to switch on the balance. "tEmP " will
appear on the display screen. Press the key, the balance will run through a "tEst
" mode. "0.000 " will appear on the display screen after a few seconds. A short warm-
up period of approx. 10 minutes is advisable for stabilisation purposes.
Start up the adjusting process by operating the key. "------------- " will appear on
the display screen for a few seconds.
The key must be pressed whilst "-------------" is on the display screen.
Subsequently, "noCAL" will appear on the display screen . "-LoAd-" will appear on
the display screen after a few seconds, followed by the nominal value of the adjusting
weight.
The calibration process can be aborted during this period by pressing the key.
Now apply the adjusting weight and calibration will take place (please wait).
" CAL " will appear on the display screen, followed by " rELoAd " a few seconds
later.
Now remove the adjusting weight from the weighing plate.
The adjusting process is completed. The adjusting weight can be re-applied in order
to check the calibration. If the displayed value is not correct, adjusting should be re-
peated.
