BenchMike Pro 2025/2050 & Z-Mike Pro 4025/4050 Instruction Handbook: Setup

4.10.7 Floating Nominal
The
Floating Nominal
function allows you to copy the current
measurement of product size (displayed as Size on the
screen) to the Nominal value. The Nominal is the desired
product size and is used to compute values such as Deviation
from the nominal size. When the nominal is updated, the lim-
its are recalculated based upon the tolerance values defined in
the Nom/Lim/Tol Setup.
NOTE: The Floating Nominal allows you to define a Nominal
value based on the current product measurement. You can also define a Nominal value through the Measurement
menu.
4.10.8 Master Measurement
The
Master Measurement
function allows you to ensure that
your products match your pre-defined master size. This func-
tion creates a positive or negative offset to the size that equals
the difference between the measured size and the size en-
tered during mastering. This offset is applied to all measure-
ments until cleared.
When you select
Single Point Mastering
, a setup wizard will
walk you through the process of defining the numeric size of the master, placing it in the measurement area for
measurement, and storing the value. Once completed, all future measurements will reference your master value.
When you select
Dual Point Mastering
, another setup wizard will walk you through the process of defining and
measuring two master products. The larger master should be slightly larger than the largest product you expect to
measure, and the smaller master should be slightly smaller than the smallest product you expect to measure. The
masters should also have a difference in size of at least 20% of the BenchMike Pro’s measurement range. For the
2025 there should be at least a 0.2 in. difference, and for the 2050, there should be at least a 0.4 in. difference.
The BenchMike Pro’s measurements will be linearly interpolated between those two master values.
