Measurement and Display Ranges
The measurement range of the DL850E/DL850EV is ±10 div, with 0 V in the center (the absolute width, or span,
is 20 div). The default display-range setting is ±5 div (the span is 10 div). Using the features listed below, you can
move and scale the displayed waveform so that parts of it that were outside of the display range are displayed.

• How to Measure the Voltage with High Accuracy
To measure the voltage with high accuracy, increase the vertical scale so that the input signal is measured
with the largest possible amplitude. To display multiple waveforms so that they do not overlap without
dividing the screen, you have to set the vertical scale to a low value. This prevents you from taking
advantage of the A/D converter’s resolution. However, if you divide the screen
and arrange
the waveforms
in the divided screens, they will not overlap, and you can raise their vertical
scales.
• Measurement Resolution
The measurement resolution varies depending on the module. For example, the 701250 (HS10M12),
701255 (NONISO_10M12), and 720210 (HS100M12) use 12-bit
A/D converters and sample the input
signal at a resolution of 150 levels per div. The 701251 (HS1M16), 701267 (HV (with RMS)), 701261
(UNIVERSAL), 701262 (UNIVERSAL (AAF)), 701265 (TEMP/HPV), 701275 (ACCL/VOL
T), 720220 (16CH
VOLT), and 720221 (16CH TEMP/VOLT) use 16-bit A/D converters and sample the input signal at a
resolution of 2400 levels per div.
