Hioki MEMORY HiLOGGER LR8450 User Manual

6.1 Performing Numerical Calculations
There are two methods for performing numerical calculations:
• Performing calculations during measurement (real-time automatic calculations)
Congure 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 congured
before starting measurement.
Calculations are performed in real time during
measurement.
(p. 197)
• 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 format.

Performing calculations after
measurement
(Manual calculations)
Numerical calculation settings are congured, and
calculations performed, after measurement.

Observe data
In the following instances, calculated values and saved data are treated as described in “11.15
Data Handling” (p. 414).
• When the waveform signicantly exceeds the range’s measurement scope (+OVER, -OVER)
• When the instrument detects a thermocouple wire break during temperature measurement (wire
break detection)
If data acquired across the calculation target channel includes the [NO DATA] points, which
resulted from communications disruption or other reasons, the data will be exempted from the
calculation target.
