CHAPTER 3 Settings and Measurement
(1)-41 Other settings
The following settings can be performed.
Setting Description
Annotation text string Set the annotation (comment) displayed in the CH.
Program Inter-CH
calculation
Set the contents of Program Inter-CH calculation.
Four arithmetic operations (addition (+), subtraction (-), multiplication (x), division (÷)) can be used for
the Program Inter-CH calculation.
* For details, refer to “<Inter-CH Op Settings>” in “(1)-6 Misc.” in “3.4 Setting Menus”.
Span setting Set the upper and lower limits of the span which the waveform is displayed.
Waveform color setting 0 to 31 for each of red, green, blue (RGB)
Line Thickness Setting 1 to 8 dots
Trace This is used to set the waveform display.
CO2 calibration Set the CO2 calibration.
In this calibration, the minimum value within a certain period of time based on the reference value
should be corrected.
This is useful in the environment CO2 concentration is low.
Adapter for AC current sensor of the wireless sensor setting: optional
(GL100-WL+GS-DPA-AC)
Perform the settings for the adapter for AC current sensor input of wireless sensors.
When the wireless sensor and adapter for AC current sensor are connected, the setting screen is displayed.
(1)-42 Input setting
This is used to select the AC clamp mode.
Setting Description
AC 1P2W Set when measured with the single-phase 2-wire.
* Power = Measured current × Voltage × Power factor
AC 1P3W Set when measured with the single-phase 3-wire.
* Power = (Measured current (ch1) × Measured current (ch2) x Voltage × Power factor
AC 3P3W Set when measured with the triple -phase 3-wire.
* Power = ((Measured current (ch1) + Measured current (ch2)) ÷ 2) x Voltage ×√3 x Power factor
This is used to select the input conditions.
Setting Description
Off The input signal is not measured. The waveform and digital display also are not performed.
1ch Current Used to select the CH1 current.
2ch Power CH1 power is displayed. The range is linked to the current. Settable only when measured with
the single-phase 2-wire.
Off when measured with the single-
phase 3-wire and 3-phase 3-wire.
ACC.
POWER
CH1 accumulated power is displayed. The range is linked to
the current.
3ch Current Used to select the CH2 current.
4ch Power CH2 power is displayed. The range is linked to the current.
ACC.
POWER
CH2 accumulated power is displayed. The range is linked to the current.
5ch to 8ch No AMP Because the amplier cannot be installed, the “No AMP” is displayed.
