5-2. Sensor unit settings
1) Sensor unit
The Sensor unit is data logging device to record the output from the built-in Si-
pyranometer, T-type thermocouples and external pyranometer or reference cell. The unit
has the Angle capturer to find the angle and direction of PV module/array. The Angle
capturer has the radial angle screen, dome, and the level, which they can be taken off
from the Sensor unit itself easily.
2) Setting up the Sensor unit
1. Setup the time on the Sensor unit and the Main unit at first.
a. Adjust the time on the Main unit , then turn off the power.
b. Connect the Sensor unit with modular cable.
c. Turn on the Sensor unit power first.
d. Then turn on the Main unit power.
e. When the LCD display on the Main unit changes to Menu screen, then the time
is synchronized.
If error message appears, check whether the modular cable or the Sensor unit
power switch is on OFF, and then try again from the start.
2. Determine whether to measure with or without the modular cable.
a. When measuring without the modular cable, make sure the Sensor unit is
working by battery. Also, this measurement requires downloading the data
from the Sensor unit to the Main unit after taking the measurement.
b. If measuring with modular cable, the battery in the Sensor unit is not needed
as long as the Main unit is plugged in with AC adapter, which can supply the
power to the Sensor unit. Also, the measuring data taken from the Sensor
