Hioki DM7275 Series - X84; Reducing Measured Value Variability (Smoothing Function)

69
Obtaining Stable Measured Values
Reducing measured value variability(smoothing function)
This function averages multiple measured values to reduce measured value variability. It can only
be enabled while the instrument is in the RUN state (p. 37).
To reduce variability in a state other than the RUN state, adjust the integration time.
The smoothing function averages the most recent measured value the set number of times and
displays the result (using a moving average). When the smoothing function is enabled, the display
refresh speed does not change, but the response time increases.
Example: Display values (D1 to D4: measured values) when the smoothing count is set to 3

1
Enable the smoothing function.
(Default setting: OFF)
2
Set the smoothing count.
˄ Increases the value by 1.
˅ Decreases the value by 1.
(Valid setting range: 2 to 100; default
setting: 4)
Important
The smoothing memory is automatically erased at the following times:
• When the smoothing, temperature
compensation
, scaling, NULL, or trigger source setting is
changed
• When the instrument is reset
• When the panel load function is used
• When a measurement error occurs
• When the instrument is turned off
• When the range is changed
