Initial Start-Up; Adjustment; Adjusting - KERN ECB N Series Operating Instruction

5.4 Initial start-up

A warm-up time of 5 minutes stabilises the measured values after switching on.
The accuracy of the balance depends on the local acceleration of the fall.
Please be sure to observe the information in the chapter on adjusting.

5.5 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.

5.6 Adjusting

Using a precision weight, the accuracy of the balance can be checked at any time
and adjusted.
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 5 minutes is recommended for stabilisation.
Operation Display
Turn on balance by pressing the ON/OFF key
Keep the TARE key pressed for 3 seconds
„CAL" – followed by the adjustment weight will be adjusted.
(example)
Place the required adjustment weight on the centre of the
weighing plate (see chap. 1 „Technical Data")
Short time later appears:
After that the balance will switch off automatically.
Adjustment has now been completed successfully.
Remove the weighed good.
An error during adjustment or the use of an incorrect adjusting weight will result in
an error message „E".
In this case repeat the adjustment.
