DC Offset adjustment function
This function automatically adjusts the offset so that the average DC current is zeroed at the
time of pressing the F key. Although this adjustment can be made while input voltage and
current are applied, it is recommended that the adjustment is performed while no input
voltage/current is applied.
- If the automatic adjustment is made while a signal with non-zero average DC current is
applied, the resulting offset will be shifted by the amount of the non-zero average DC current
that existed in the input signal.
- As the adjustment is cleared when the range is changed, it is recommended to use this
function after selecting a fixed range, instead of using the AUTO range.
- When the POWER switch is turned off, the adjustment will be cleared.
2 _ Voltage Range Select the measurement range of the input phase selected in Setting Ch
(V/I Range). Select the range in accordance with the rated power supply
voltage of the EUT. In the AUTO mode, the range will be fixed once the
test is started.
The input phase selected (L1, L2 or L3) will be shown at the underlined
position of the menu item. When "Volt. Scaling" is used, the menu will
show the measurement range that corresponds to the scaling.
When "Linked" is selected in F5 Channel Linkage, the input phase
selected will not be shown at the underlined position of the menu item.
The menu will be that for the L1 phase. AUTO
3 _ Current Range Select the measurement range of the input phase selected in Setting Ch
(V/I Range). Select the range in accordance with the rated power supply
current of the EUT. In the AUTO mode, the range will be fixed once the
test is started.
The input phase selected (L1, L2 or L3) will be shown at the underlined
position of the menu item. When "Curr. Scaling" is used, the menu will
show the measurement range that corresponds to the scaling.
When "Linked" is selected in F5 Channel Linkage, the input phase
selected will not be shown at the underlined position of the menu item.
The menu will be that for the L1 phase. AUTO
4 Channel Linkage Select the "Linked" or "Independent" status between the lines L1, L2,
and L3. When "Linked" is selected, independent setting of L1, L2, and
L3 cannot be made.
The "Linked" setting is applied to voltage and current ranges. Linked
5 Return Terminates the V/I Range setting. –
6 Wiring Method Select a wiring method for a measuring circuit. 3P4W
7 PLL Source Select a source to synchronize with the AC power frequency.
The voltage or current signal of each of the L1, L2 and L3 phases can be
selected. To use the EXT SYNC INPUT input signal, select EXT. Voltage L1

This item becomes valid when 3P3W is selected in F1 Wiring Method. In
the case of EUT that doesn't use the neutral line, the voltages between
lines (line voltages) will be calculated from the measured voltages of
each phase. Disable
9 Return Terminates the Input Config. (detailed measurement setting) function. –
10 DC Offset Controls the DC offset of the internal circuit. –
11 Prev/Next Page 4/4 Switches to another menu page. –
F key: Function key. You can also use the ESC key to return.
