Switch
Function
SET
The integrated value of electric energy is changed to the usual display and an enlarged display.
If it continues pushing 3 seconds or more, it will change to setting mode.
In setting mode, it is used for the determination of a set point.
RESET/SHIFT
Various kinds of alarms are reset. The maximum value and the minimum value are reset in the maximum
minimum measurement display. In setting mode, it is used for movement of a setting item.
MODE
The usual general measurement display and harmonic measurement (voltage, current) display are changed.
In setting mode, it is used for the change of a setting item.
MAX/MIN
The usual measurement display and maximum value or minimum value display are changed.
＋ ， －
The measurement display element of the main monitor is changed.
In setting mode, it is used for change of a set point.
DISPLAY
A phase (between lines) display of current (voltage) is changed. Used in case it terminates setting
mode. And, it is used in case it returns the display combination of a measurement factor.
Convenient functions
(1)
In case a measurement change or a phase change is performed and the original screen composition is not clear
anymore, DISPLAY is pushed for more than 3 seconds or it's no operation for 10 minutes and returns to original
screen structure.
(2)
Even if it stops operation with setting mode, it returns to the display mode in 10 minutes.
7 segment displays
This product shows the guidance in various setting using 7 segment displays besides a display of a measurement value.

Term
(1) Range
Measuring range of each measurement
① Voltage range：Measuring range of voltage measurement (Pimary voltage value for 0 to 150V / 0 to 300V)
② Current range：Measuring range of current measurement (Pimary current value for 0 to 5A / 0 to 1A)
③ Active power range / reactive power range：Active power / reactive power measurement range (Active and
reactive power values [VT ratio × CT ratio] depending on voltage range and current range)
④ Power factor range：Power factor measurement range
⑤ Frequency range：Frequency measurement range
(2) Intrinsic sensitivity
Display specific sensitivity：Maximum scale value
that can be changed with the range set to 100%.
Output specific sensitivity：Maximum output value
that can be changed with the range set to 100%.
(3) Full scale
Maximum scale value for bar graph display
(4) Power receiving / Power transmission
The multimeter measures power receiving (+ power) and power transmission (- power) depending on the direction
of the current flowing through the current transformer.
