Adjustment - KERN KMF-TM Operating And Installation Instructions

14 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,
each display unit with connected load cell 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 weighing system 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 display unit periodically in weighing operation.
•
Prepare the required adjustment weight. The weight to be used depends
on the capacity of the scale. Carry out adjustment as near as possible to
the scale's maximum weight. Info about test weights can be found on
the Internet at: http://www.kern-sohn.com.
•
Observe stable environmental conditions. Stabilisation requires a certain
warm-up time.
Access to service menu „tCH"is locked in verified balances.
To disable the access lock, destroy the seal and actuate the adjustment
switch. Position of the adjustment switch see chap. 13.
Attention:
After destruction of the seal the weighing system must be re-verified by an
authorised agency and a new verification wire/seal mark fitted before it can
be reused for applications subject to verification.
