EKO INSTRUMENTS CO., LTD. I-V Curve Checker MP-11 Instruction Manual Ver.7
Setup the following parameters and press Enter button.
[Area] PV module area
[Alpha] Short Circuit Current Temperature Coefficient
When the catalog value unit is in [%/deg],
convert the unit to [A/deg] and then enter the
value. For example:
Alpha＝0.06 [%/deg]
When Short Circuit Current Isc = 8.63A, it can
be converted into:
(8.63/100) × 0.06 ＝0.00578 [A/deg]
[Beta] Open Circuit Voltage Temperature Coefficient
When the catalog value unit is in [%/deg],
convert the unit to [V/deg] and then enter the
value. For example:
Beta＝-0.33 [%/deg]
When Open Circuit Voltage Voc = 45.4V, it can
be converted into:
(45.4/100) × (-0.33) ＝-0.14982 [V/deg]
[Rs] Series Resistance
[K] Curve Correction Factor
[Connection] S：Number of modules in series
P： Number of modules in parallel
When the parameter editing is complete, press the Enter button.
After the Enter button pressed, the parameter saving message
appears as shown on the left and the parameter is saved.
NOTE: However, the parameter will not be saved in the parameter
list if the Sensor Unit is not used and selected [NO] for the irradiance
and temperature parameter setting since it will be just a temporary
parameter setting.
NOTE: Status of Sensor Unit connection is shown in right-upper side
of main menu display.
2) Selecting Registered Parameter
Select the [SELECT] from the Parameter Menu screen using the Up/Down buttons; the [PARAMETER
LIST] is displayed. Bring the cursor to the parameter name which to be setup and press [Enter] button
to run the measurement with this parameter setting.
3) Deleting Parameters
Select [ERASE] from the Parameter Menu screen using the Up/Down buttons; the [PARAMETER LIST] is
displayed. Bring the cursor to the parameter name which to be deleted and press [Enter] button to
delete.
