IMPORTANT:
all slots must be filled in, including
any zeroes before and after the decimal.
IMPORTANT:
the settings configured in this
menu are stored in memory and are saved even if the
device is turned off. If the generator configurations
are changed or if individual modules are now under
test, these values must be updated.
Once the parameters are entered, the variable name
should be pressed again to set the new value in
memory. The name changes back to blue and the
new configured value will appear in the box below
the name. If the value that appears is not the value
configured, it must be re-entered making sure that
there is a digit in all hyphened spaces.
5.5.6 Sensor settings
IMPORTANT:
before starting a new set of
measurements, make sure that the values configured
in this section match those of the sensor used.
For the correct extrapolation of the measured
I-V curves, it is necessary to enter the
characteristic parameters of the sensors used
to characterize the measurement conditions.
These parameters are necessary to identify the
difference between the measurement taken and
the the STCs, and the extrapolation to STC, so that
process to calculate the I-V curve in STC can take
place.
5.5.6.A Irradiance sensor setup
Within the irradiance sensor setup, the I
SC
of the
reference cell, and the alpha coefficient of variation
with the temperature must be set. Both values will
appear on the calibration report delivered along
with the rest of the device results. To set these
values enter:
· Settings-> Sensor settings
To configure one or both parameters, the name
of the variable to configure must be selected
which will shortly turn red, filled with hyphens.
Enter the desired value by ensuring that as many
digits are entered as the displayed hyphens,
including as many leading or trailing zeros.
IMPORTANT:
all slots must be filled in, including
any zeroes before and after the decimal.
IMPORTANT:
the settings configured in this
menu are stored in memory and are saved even if
the device is turned off. If the module model under
test is changed, these values must be updated.
5.5.6.B Temperature sensor setup
Part of the temperature sensor setup is choosing
the right sensor (PT-1000, reference module or
E-Temp) and configuring the device accordingly.
These configurations can be accessed and changed
through Settings, Sensor Settings and pressing
the box below the current sensor settings until the
desired selection appears:
· PT-1000:
if using the PT-1000, it is necessary
to choose what is being measured: a module
under test (Tmod), a reference cell temperature
(Tsen), an ambient temperature (Ta) or, if it is not
being used – OFF must be selected. To do this,
activate the corresponding PT-1000 name (PT_1,
PT_2, or PT_3) until the measurement type for
that PT-1000 appears below it. The selected PT-
1000 code will be displayed on the main screen
as indicated in
section 5.2.1.
· MOD REF:
if using a reference module, both
the V
OC
and the beta coefficient of variation with
the temperature must be set. To configure the
parameters, the name of the variable to configure
must be selected which will shortly turn red,
filled with hyphens. Enter the desired value by
ensuring that as many digits are entered as the
displayed hyphens, including as many leading or
trailing zeros.
· E-Temp:
if using an infrared temperature sensor,
only a connection of the E-Temp with the E-1000
must be insured.
