1.9 Other Features
Initializing Setup Parameters (For procedures, see section 8.2)
You can use this feature to restore the setup parameters to the factory default settings.
Zero-Level Compensation (For procedures, see section 8.3)
Zero-level compensation refers to the process wherein this instrument creates a zero input condition in
its internal circuitry and sets the zero level to the level at that point. Zero-level compensation must be
performed to satisfy the specifications of this instrument. When the measurement range is changed,
zero-level compensation is performed automatically. However, if the measurement range is not
changed for a long time, the zero level may shift due to environmental changes around the instrument.
In this case, you can manually perform zero-level compensation.
D/A Output (Option; for procedures, see section 8.4)
You can output voltage, current, active power, apparent power, reactive power, power factor, phase
angle,frequency,voltagepeak,currentpeak,andintegratedvaluesasa±5VFSDCvoltage.You
can output values using 4 output channels on the WT310E/WT310EH and 12 output channels on the
WT332E/WT333E.
Remote Control (Option; for details, see chapter 5 of the Getting
Started Guide, IM WT310E-02EN)
On models with the /DA4 or /DA12 option, you can control this instrument using a negative TTL pulse
signal and output logic signals.
External Input
The following five types of control signals are available.
• EXTHOLD
Holds displayed values or releases the held state.
• EXTTRIG
Updates the displayed values when they are being held.
• EXTSTART
Starts integration.
• EXTSTOP
Stops integration.
• EXTRESET
Resetstheintegrationresult.
External Output
The following signal is output during integration.
INTEGBUSY
This signal is output continuously from the start to the stop of integration.
