Gauge Memory (BST)
The Elcometer 456 versions are supplied with a varying level of
memory:
Model E: No memory
Model B: The Model B gauge’s ‘rolling statistics’ provides
accurate statistical values for all measurements
taken since the statistics were last cleared
(Display/Clear Statistics). The last 5 readings,
however, can be displayed by pressing the Data
softkey.
Model S: 1,500 readings can be stored into the gauge’s memory
Model T: A total of 150,000 readings can be stored into the
gauge’s memory either in a single batch or in up to
2,500 batches (see Batching on page 26). Each
batch can be individually named and can have its
own unique calibration.
Limits (ST)
During the inspection process coatings can often have specified
minimum and/or maximum thickness values.
For example, coatings that have been applied too thinly over a
surface profile can lead to rust spots appearing on the peaks of the
profile. Similarly too thick a coating can also lead to premature coating
failures.
Users can program upper and/or lower warning limits into the
Elcometer 456 gauge by selecting Menu/Set Limits/Set Upper or
Menu/Set Limits/Set Lower.
To switch the limits on, the user should ensure that the Enable Limits
radio button is checked.
Ÿ When an Upper Limit has been set up and enabled the “ ” icon is
displayed.
Ÿ When a Lower Limit has been set up and enabled the “ ” icon is
displayed.
Ÿ If both Upper and Lower limits have been set up and enabled then
the two icons are displayed together as “ ”.
