Performing Numerical Calculations
6.1 Performing Numerical Calculations
There are two methods for performing numerical calculations:
• Performing calculations during measurement (real-time automatic calculations)
Configure the desired numerical calculations and start measurement. Calculations will then be
performed in real time during measurement.
You can review the most recent numerical calculation results on the [Wave+Value] waveform
screen.
• Performing calculations after measurement (manual calculations)
Use the instrument’s control keys to start the calculation after measurement has completed.
Performing calculations during
measurement
(Real-time automatic calculations)
Numerical calculation settings are configured
before starting measurement.
Calculations are performed in real time during
measurement.
(p. 150)
•You can review the most recent calculated values
on the waveform screen ( [Wave+Value] display).
•You can also save calculated values for each
interval in text (CSV) format.

Performing calculations after
measurement
(Manual calculations)
Numerical calculation settings are configured, and
calculations performed, after measurement.

Observe data
In the following instances, calculated values and saved data are treated as described in “11.13
Data Handling” (p. 302).
• When the waveform significantly exceeds the range’s measurement scope (+OVER, -OVER)
• When the instrument detects a thermocouple wire break during temperature measurement (wire
break detection)
