8-6. Data Display Menu
The Data Menu screen is displayed when [DATA] button is pressed from the Main Menu screen.
[SEARCH] Searches and displays the measurement data
[Irr vs Parm Gaph] Displays graph for the irradiance and each PV
module parameter.
[ERASE] Deletes already saved data.
1. Searching Saved Data
The Data List screen is displayed when [SEARCH] is selected, and the data which are saved in the Main Unit
memory are displayed in a list.

2. Displaying Data Graph
Select the date of data to be displayed on graph from the data list on Data List screen by using the Up/Down
buttons and press [Enter] button.
By pressing Enter button repeatedly, the graphs are displayed in the following order:
 I-V Curve (x-axis: Voltage (V), y-axis: Current (A))
 P-V Curve (x-axis: Voltage (V), y-axis: Power (W))
 (dI/dV)-V Curve (x-axis: Voltage (V), y-axis: Derivative Value)
 Measurement Information
 Characteristics Value 1/2
 Characteristics Value 2/2
：(Repeat above)
I-V Curve (x-axis: Voltage (V), y-axis: Current (A))
I-V curve graph shows the voltage-current characteristics of the PV
module under the conditions of irradiance, ambient temperature and
the PV back surface temperature.
The crossing point of curve on the x-axis (voltage) is called Open
Circuit Voltage, Voc, and the crossing point of curve on the y-axis
(current) is called Short Circuit Current, Isc.
