Curve measurement:

Before starting with this procedure, make sure you follow the steps to conﬁgure

and connect the device properly.

Also, it is recommended to perform the measurements with the following conside-

rations:

- Perform the measurements during clear sky and no wind.

- Make sure the calibrated cell is on the same plane as the modules of the test

circuit without making shadows to it.

- Measure the temperature on different points of the test circuit.

- Perform the measurements with a radiation level between 800 and 1200 W/m2,

and never under 600 W/m2.

- Avoid an angle of incidence of the sun superior to 40 °.

Temperature measurement:

Temperature measurement is a process that can be performed in several ways

(Section 5.5.6.B). Anyway, Entec Solar always recommends to use the E-Temp as

it is faster, easier and more accurate.

To power on the E-Temp, press lightly and only one time the power on button, and

wait a couple of seconds for it to show the start screen. In order to power off the

device, keep pressed the power button for 5 seconds.

IMPORTANT: During the start of the device, it is important to not press seve-

ral times the power on button, and not to press it for too long, as this may turn off the

device.

On the standby screen, you can perform measurements pressing one time the

power button located on the center of the device. When you measure an I-V

curve, if you have the E-Temp selected (Section 5.5.6.B), the device will beep and

a message will show on screen stating that it is waiting for the E-Temp

temperature measurement.

Perform the temperature measurement to proceed with the measurement.
