2.2 Setting the Horizontal and Vertical Axes
Vertical Axis (Voltage Axis) <Section 5.3>
Setting the Voltage Sensitivity
The vertical sensitivity setting is used to adjust the displayed amplitude of the waveform
for easy viewing. The vertical sensitivity (V/div) is set by assigning a voltage value to
one grid square (1 div) on the screen. The vertical sensitivity changes by switching the
input section to an attenuator with different values of attenuation. The sensitivity is
changed in steps as in “1 V/div to 2 V/div to 5 V/div.”
1 div = 1.000 V
1 div = 0.500 V

Measurement Range and Display Range
The measurement range of the DL750/DL750P is
±
10 divisions (20 divisions of absolute
width (span) around 0 V.
The display range of the screen is
±
5 divisions (10 divisions of span). The following
functions can be used to move the displayed waveform and display the waveform
outside the display range by expanding/reducing the displayed waveform.
• Move the vertical position -> See page 2-6.
• Set the offset voltage -> See page 2-6.
• Zoom in or out of the vertical axis (expand/reduce) -> See page 2-7.

Note
•
For Measuring the Voltage with High Accuracy
To measure the voltage with high accuracy, set the voltage sensitivity so that the input
signal is measured with as large amplitude as possible.
•
Measurement Resolution
The measurement resolution varies depending on the module. For example, the 701250
(HS10M12) and 701255 (NONISO_10M12) sample the input signal using a 12-bit A/D
converter at a resolution of 150 levels per division. The 701251 (HS1M16), 701260 (HV
(with RMS)), 701261 (UNIVERSAL), 701262 (UNIVERSAL (AAF)), 701265 (TEMP/HPV),
and 701275 (ACCL/VOLT) sample the input signal using a 16-bit A/D converter at a
resolution of 2400 levels per division.
