When are dimensions stored in the ND 2100G database?
Visible dimension values are displayed on the screen and are stored as
records in the ND 2100G database when the ENTER key is pressed,
or when a Trip function is executed.
Hidden dimensions are used to perform operations, make decisions or
manipulate variables, and are not displayed on the screen or stored in
the database.
What can formulas do?
Formulas can be constructed to produce a wide variety of results
depending on channel input values, tolerance tests, parallel port
conditions, time, temperature and other test and environmental
conditions.
Formulas can:
„ Assign values to dimensions derived from channel inputs or other
dimensions
„ Perform operations such as closing a relay contact, sending data to
the parallel port, sending a message on the serial port or printing a
report
„ Perform conditional tests of measurement results, tolerance test
results, parallel port data, or environmental conditions and make
decisions based on the results
„ Control the sequence of steps in a measurement process
„ Semi-automate a measurement process
„ Display messages and prompts for keyboard input
„ Define custom ND 2100G functions
