7352 Series Digital Multimeter Operation Manual
5.9.2 Smoothing Calculation
5-27
When the smoothing count, N, is set to 3, the operation is as follows:
The smoothing calculation result, D(sm), at the nth measurement, which exceeds the smoothing
count, is shown below:
2. Setting the smoothing count
The smoothing count is set in
.
The smoothing count can be set between 2 and 100.
3. Restarting the smoothing calculation
The smoothing calculation restarts from N=1 when any of the following conditions occur.
• The power is turned on.
• The smoothing count is changed.
• The NULL calculation is performed.
4. Canceling the smoothing calculation
The smoothing calculation is canceled when any of the following conditions occur.
• The
key is pressed while the smoothing calculation is performed.
• The measurement function is changed.
• The *RST command is executed.
5. Smoothing calculation and overload (OL)
If the overload occurs during the smoothing process, this measured value is ignored.
(All measurement data except for OL data can be used in the smoothing calculation.)
