IM WT3001E-51EN
Explanation
The numeric data can be output using ± 5-V FS DC voltage from the D/A output
connector on the rear panel. Up to 20 items (channels) can be specified.
CAUTION
Do not short the D/A output terminal or apply external voltage to it. If you do, the
instrument may malfunction.

ATTENTION
Ne pas court-circuiter la borne de sortie D/A et ne pas y appliquer de tension
externe. Le cas échéant, un dysfonctionnement de l’instrument est possible.
Limitations on the D/A Output Function by Measurement Modes
There are limitations on the setting and execution of the D/A output in measurement
modes other than normal measurement mode.
• There is a limitation on the numeric data that can be measured and delivered through
D/A output in the measurement modes listed below. For details on the numeric data
limitations, see appendix 11 in the User’s Manual IM WT3001E-01EN. This instrument
outputs 0 V where no numeric data exists.
• Wide bandwidth harmonic measurement mode
• Waveform computation mode
• FFT mode
• The D/A output function cannot be used in the following measurement modes. This
instrument outputs 0 V on all channels.
• IEC harmonic measurement mode
• Voltage fluctuation and flicker measurement mode
• Cycle-by-cycle measurement mode
D/A Output Item
• Selecting the Measurement Function
• The types of measurement functions that can be selected are the items that are
indicated in “Types of Measurement Functions during Normal Measurement”
of section 2.2, “User-Defined Function” and “Corrected Power” of section 2.5,
“Measurement Functions of Integration” of section 2.6 in the User’s Manual IM
WT3001E-01EN, as well as “Motor Evaluation Function (Option)” of chapter 1, “Delta
Computation” of chapter 6, and “Harmonic Measurement in Normal Measurement
Mode (Option)” of chapter 7 in this manual.
• You can also select not to output the measurement functions (None). For channels
that are set to None, 0 V is output since no corresponding data exists.
• If the range mode (see section 3.3) is set to fixed, the D/A output of a channel
whose measurement function is set to Z, Rs, Xs, Rp, Xp, or F1 to F20 is fixed to 0 V.
It is output when the range mode is set to manual.
