Adapter for AC current sensor (GS-DPA-AC: optional) setting
Performs the setting related to the input of adapter for AC current sensor.
The Setting screen is displayed at the end of the group by connecting the adapter for AC current sensor and
turning On the GL840's power.

(1)-44 EU setting
This is used to unit-convert the measurement signal.
Refer to "<Setting example: For voltage input>" in "(1)-5 EU (Scaling settings)" in "3.4 Setting Menus".
Even if the scaling setting is applied to the original measured value of CH, the accumulated power is not
reflected in the accumulated power CH.
Set when measured with the single-phase 2-wire.
* Power = Measured current × Voltage × Power factor
Set when measured with the single-phase 3-wire.
* Power = (Measured current (ch1) × Measured current (ch2) x Voltage × Power factor
Set when measured with the triple -phase 3-wire.
* Power = ((Measured current (ch1) + Measured current (ch2)) ÷ 2) x Voltage ×√3 x Power factor
The input signal is not measured. The waveform and digital display also are not performed.
Used to select the CH1 current.
CH1 power is displayed. The range is linked to the current.
CH1 accumulated power is displayed. The range is linked to
the current.
Used to select the CH2 current.
CH2 power is displayed. The range is linked to the current.
CH2 accumulated power is displayed. The range is linked to the current.
Because the amplifier cannot be installed, the "No AMP" is displayed.
50, 100, 200A
(20, 50, 100kW) It is linked to the current range.
