Setting the Voltage Range
The voltage range setting is used to adjust the displayed amplitude of the waveform so
that it can be easily observed. The voltage range is set using a voltage across the top
and bottom edges of the waveform display area (10 divisions). The voltage range
changes by switching the input section to an attenuator with different values of
attenuation. The sensitivity is changed in steps as in 1 V to 2 V to 5 V.

Measurement Range and Display Range
The measurement range of the SL1400 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.

Note
•
For measuring the voltage with high accuracy
To measure the voltage with high accuracy, set the voltage range 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), 701267 (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.
