Measurement Procedure
To conguring measurement settings automatically
Clicking [Auto range] on the waveform screen automatically species the sampling rate,
measurement range, and zero position of the input waveform and start a measurement.
Refer to “3.7 Measuring Signals With the Auto-range Setting” of Quick Start Manual.
To load settings previously registered
Load the settings le on the le screen.
Refer to “4.3 Loading Data” (p. 94).
To automatically load saved settings at the time of startup
Congure the setting for the instrument so as to load the le containing the instrument settings at
the time of startup.
Refer to “Automatically loading the settings (Auto-setup function)” (p. 95).
Initializing the instrument (Restoring the basic settings)
Select > [System] > [Initialize] to restore the instrument settings to the factory default.
The setting after the initialization is suitable for simple measurement.
If any unexpected or complicated behavior is observed, initialize the instrument.
Refer to “6.2 Initializing the Instrument” in Quick Start Manual.

Setting Measurement Conditions
1.2 Setting Measurement Conditions
You have to set conditions required for measurement, such as the sampling rate ([Sampling]) and
recording length ([Shot]).

Click the [Sampling] box, and then choose a sampling rate from the list.
Refer to “Sampling rate setting guideline” (p. 7).
20 MS/s, 10 MS/s, 5 MS/s, 2 MS/s, 1 MS/s,
500 kS/s, 200 kS/s, 100 kS/s, 50 kS/s, 20 kS/s, 10 kS/s, 5 kS/s, 2 kS/s, 1 kS/s,
500 S/s, 200 S/s, 100 S/s, 50 S/s, 20 S/s, 10 S/s, 5 S/s, 2 S/s, 1 S/s
When the real-time save is set to [On], due to the combination of the number of channels to be saved and
save destinations, the maximum sampling rate that can be set varies as follows:
Maximum sampling rate that can be
chosen
Destination to save
Number of channels to be saved Built-in SSD USB ash drive*
12 channels or less 5 MS/s 1 MS/s
33 to 64 channels (SSD)
25 to 64 channels (USB ash drive)
2 MS/s 500 kS/s
13 to 32 channels (SSD)
13 to 24 channels (USB ash drive)
1 MS/s 200 kS/s
65 channels or more 500 kS/s 100 kS/s
(When Model U8991 is installed, double the number of its channels and nd the maximum sampling rate.)
*: Only if Model Z4006 USB Drive, a Hioki-designated option, is used, the real-time save operation with the
instrument is guaranteed
