4 QB Series Operation Manual
1.5 Special Information
The QB Series balance is a sensitive, precision weighing instrument and should always be treated with care.
While every attempt is made prior to shipping to ensure that your balance arrives ready-to-use, uncontrollable
events during the shipping process may make it necessary to calibrate the device before being used.
While not absolutely necessary, we recommend that you perform a span calibration prior to using the balance for
the first time. Even though your QB Series balance was carefully calibrated at the factory, shipping and the
effects of specific gravity can have a negative impact on accuracy. Review Section 3.0 on page 14 for instructions
on this feature.
In the event that the device fails to operate properly, contact your Rice Lake Weighing Systems dealer for
assistance.
