5.7 Auto Zero Maintenance
The MSI-4260 IS employs an Auto Zero Maintenance (AZM) mechanism to adjust the zero reading to the center-of-zero, which
is defined as the weight reading within 1/4 d of zero. AZM continuously adjusts zero to maintain the center-of-zero. It is
recommended that AZM is on to maintain the highest accuracy. However, there are circumstances when it should be turned off.
This can happen when minor variations of weight occur while picking up scale attachments and the variations fall within the
AZM capture window. The AZM capture window (usually 1 d) and capture time (usually eight seconds) can be adjusted by MSI
to meet custom requirements. The settings of AZM are dictated in Legal for Trade standards and cannot be adjusted.
Use the following steps to set up the auto zero maintenance.
1. Remove the hex seal screw from the MSI-4260 IS using the steps from Section 5.1 on page 18 .
