• SCALING Key (See section 4.5)
Displays a menu for setting the VT ratio, CT ratio, or power coefficient for each input
element. These coefficients are used to convert the VT/CT output or the power
derived from measuring the VT and CT outputs to the voltage, current, and power of
the object being measured.
• LINE FILTER Key (See section 4.8)
Displays a menu for setting the filter that is inserted into the measurement circuit
within the WT3000 for each input element.
• SHIFT+LINE FILTER (FREQ FILTER) Key (See section 4.8)
Displays a menu for setting the filter that is inserted into the frequency measurement
circuit within the WT3000 for each input element.
• AVG Key (See section 4.9)
Displays a menu for setting the function that calculates the average of measured
values.
• SYNC SOURCE Key (See section 4.7)
• Displays a menu for setting the synchronization source for each wiring unit. The
synchronization source defines the period (measurement period) over which the
sample data is acquired for determining the numeric data (measured values) such
as voltage, current, and power.
• If all elements are selected with the SHIFT+ELEMENT (ALL) key as explained on
the previous page, the synchronization source of all input elements can be set
collectively.
• UPDATE RATE Key (See section 4.10)
Displays a menu for selecting the acquisition interval (data update rate) of the
sampled data that is used to determine the numeric data (measured values) such as
voltage, current, and power.
• HOLD Key (See section 4.11)
When the HOLD key is pressed and the HOLD indicator illuminates, the measurement
and display operation is aborted, and the numeric data display is held. Pressing the
HOLD key again turns OFF the HOLD indicator and restarts the updating of the
numeric data display.
• SINGLE Key (See section 4.11)
If the SINGLE key is pressed while in the hold condition, the measurement is
performed once at the specified data update rate and the WT3000 returns to the
hold condition.
