IMPORTANT:
the charge level of the batteries
are for guidance only of a standard battery type
and depend on many variables such as the ambient
temperature, the rate of use of the device, the
battery age, manufacturing differences between
different batteries, etc. These levels may change
over time and cause the battery to discharge earlier
than intended or even jump between levels faster
than the percentages described in this section. As
the device is used, these levels may change and the
user should take this into account in order to not
run out of battery in the middle of a measurement
procedure.
4.3 Memory card insertion
The E-1000 and E-Sens store all the measured
data on SD cards, the E-Sens uses a micro-SD card.
Although, both devices work without these cards,
they lose the ability to store the data. The use of top
brand SD cards is recommended to avoid possible
data loss or memory corruption. The devices come
with the memory cards required by default. Before
each use, make sure that the SD cards are correctly
inserted and working properly to store all the
measurements.
The cards must be inserted in the slots found in the
upper part of each of the devices.
(Figures 2.1. y
2.4.).
IMPORTANT:
the insertion and removal of the
cards must be performed when the devices are off
to avoid damage and the possibility of losing the
stored data.
IMPORTANT:
the format of the cards must be
FAT32.
4.4 Initial configuration
The E-1000 has been designed for ease of use and
minimal configuration.
However, a basic configuration is required before
each measurement campaign. The main steps that
must be followed in the configuration of the E-1000
before starting a measurement are listed below:
- 1) Setting the E-1000 time to local time and
synchronizing the E-1000 with the E-Sens.
(See
section 5.5.11.A.)
- 2) Configuration of the characteristics of the
module and the generator under test: the E-1000
uses the main electrical characteristics of the
module under test (V
OC
, I
SC
, V
M
, I
M
,
α
, ẞ y N

, that
have to be provided by the manufacturer) as well
as the configuration of the generator (number
of modules in series and parallel to calculate
the series resistance and the parameter k, both
necessary to carry out the extrapolation to STC
according to the IEC-61829 standard.
(See
section 5.5.4.).
- 3) Configuration of radiation and temperature
sensors¹: configuration of the calibration values
of the reference cell (irradiance sensor) and
selection of the cell temperature measurement
method (I.E. PT-1000, reference module, E-Temp)
as described in section 5.2.2.A.
- 4) Selection of the file name for data storage
(See section 5.2.2.E.)
- 5) Selection of measurement options and saving
(auto-save, automatic measurement, continuous
measurement, barcode reading, etc, as described
in section 5.4.
)
.
For a more detailed description of how to carry out
the previous steps, see the corresponding sections.
All these settings, except for the measurement
option, are saved in the device even when it is
turned off. Therefore, it will only be necessary to
carry out this configuration at the beginning of a
new measurement campaign, when changing the
module or generator type under test or to modify
the name of the file.
