The selected math calculation is enabled by simply pressing the MATH key. When enabled,
the MATH annunciator turns on and the calculation type (NONE, POLY, %, or % DEV) is dis-
played. Also, one of the following messages is briefly displayed:

Math is disabled by pressing MATH a second time.
Additional math operations
In addition to the math performed on single readings described above, the Model 2002 has
these math operations:
• Math performed on buffered readings (maximum and minimum values, average, and
standard deviation).
• Math performed on single readings as part of a pass/fail limits test.
• Math performed on scanned readings (ratio and delta).
