Math
Model 2000 math operations are divided into four categories:
• mX+b and percent
• dBm and dB calculations
• Statistics of buffered readings
• Limit testing
The first two categories are discussed here; buffered reading statistics and reading limit test-
ing are described in Section 3 — Measurement Options.
The procedure to select and configure a math operation is summarized as follows:
1. Press SHIFT then the appropriate math key.
2. Configure the parameters for the math operation. Press ENTER when done. (Press
SHIFT then the related math function to end the calculation.)
NOTES Once enabled for a function, the mX+b and percentage calculations are in effect
across function changes.
The Model 2000 uses IEEE-754 floating point format for math calculations.
MX + B
This math operation lets you manipulate normal display readings (X) mathematically accord-
ing to the following calculation:
Y= mX + b
where: X is the normal display reading
m and b are user-entered constants for scale factor and offset
Y is the displayed result
