3.8 Using D/A Output
97
Example uses
D/A output can be used in combination with a data logger or recorder. For more information about the output
voltage, output resistance, response time, and output update rate, see "Chapter 5 Specifications" (p.135).
• When using a VT ratio or CT ratio, output voltages are determined by multiplying the range by the VT ratio
or CT ratio.
• When the measurement range is set to auto-range operation, the output rate for analog output, D/A out-
put, and high-speed level output will also change with changes in the range. When measuring lines char-
acterized by abrupt changes in measured values, exercise care not to mistake the range conversion. It is
recommended to use a fixed range in measurement applications such as this.
• The response time for the instrument’s analog output and D/A output is 0.6 s. (when the timeout is set to
0.1 s)
With measurement lines that change faster than the output response time, note that the output voltage
may contain an error component.
When the timeout is set to other than 0.1 s, refer to "3.2.7 Setting the Timeout" (p.55).
• Analog output and D/A output generate output consisting of instantaneous values that are measured
every 200 ms. High-speed active power level output is updated once every period of the input that is set
as the synchronization source. Consequently, analog output will change even in the display hold state and
during averaging processing.
• Output of 0 V is generated while displaying invalid data.
• When using a VT ratio or CT ratio, the value obtained by multiplying the range by the VT ratio or CT ratio
serves as the 1 V RMS value.
• When the measurement range is set to auto-range operation, the output rate for waveform output will also
change with changes in the range. When measuring lines characterized by abrupt changes in measured
values, exercise care not to mistake the range conversion. It is recommended to use a fixed range in mea-
surement applications such as this.
• Waveform output will change even in the display hold state and during averaging processing.
