Measure the commercial power supply
Deciding on the horizontal axis (time axis) range
The horizontal axis (time axis) range is calculated from the frequency and cycle.
f [Hz] = 1/t [s] (f: frequency; t: cycle)
Example: When the measurement frequency is 50 Hz.
1 cycle is t = 1/50 [s], i.e. 20 ms.
When the horizontal axis (time axis) is set to 20 ms/div, exactly 1 cycle will be displayed in 1 division (1
square).
Vertical axis (Voltage axis) range
If you change the range during a measurement, the measurement will restart.
3 Set the saving conditions

SAVE
key allows saving measured data
under the configured saving conditions immediately.
[Yes]
Pressing the
SAVE
key each time allows saving
measured data after the operator checks and
configures the saving conditions.
For example, the saving conditions listed below will be displayed on
the screen as shown above.

Tip
To observe waveforms on the instrument, set the
[Save Type]
to
[Wave Binary]
. To observe
them on a computer, set it to
[Text]
. Data saved in the text format cannot be observed on the
instrument.
