7.5 Connection of peripheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they
are ideally tuned to your balance.
8 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 for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
•
Observe
(see chapter 1) is required for stabilization.
•
Ensure that there are no objects on the weighing pan.
•
Avoid vibration and air flow.
•
Always carry out adjustment with the standard weighing platform in place.
•
To cancel internal adjustment, press the ON/OFF key.

When an optional printer is connected and the GLP function is connected,
the adjustment log will be edited, see chap. 8.4
8.1 Automatic adjustment via PSC function
Force-compensated scales react sensitively to changes in temperature. The higher
the sensitivity of the scale, the more pronounced the effect. The temperature
controlled PSC function enables the scale to automatically correct this effect.
PSC stands for Perfect Self Calibration and facilitates fully automatic internal scale
adjustment by means of an internal weight, based on time and/or temperature
criteria.
Adjustment in weighing mode is carried out automatically under the following
conditions:
(1) If there is a change in ambient temperature (∆t 1°C)
(2) When about four hours has passed since the previous calibration.
(3) When the balance is switched from standby status to weighing mode
and condition (1) or (2) has been met.
