9 P1 CAL - 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.
9.1 P1-01 External adjustment
Carry out adjustment with the help of the recommended adjustment weight (see
chapter 1 “Technical Specifications”).
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
Sample dishes must be in place. During the adjustment process no objects
should be on the sample plate.
The ESC key may be used to cancel the adjustment.
Errors during adjustment or the use of an incorrect adjusting weight will
result in an error message. Repeat adjustment.
If objects are location in the sample dish during adjustment, the error report
Er1 Hi will be displayed.
Return to weighing mode:
Press the ESC-key repeatedly until the query ”SAVE?“ appears.
Confirm query by pressing the PRINT-key or reject it by pressing the ESC-
key.
Wait until the weighed value for
the required adjustment weight
appears. Place adjustment weight
in the centre of the sample dish.
If the adjustment was successful,
this will be followed by automatic
return to the menu.
