Resolution of the displayed values
In the display, set values can be adjusted in fixed increments. The number of decimal places depends on the device
model. The values have 4 or 5 digits. Actual and set values always have the same number of digits.
Adjustment resolution and number of digits of set values in the display:

USB port (front side)
The frontal USB port, located to the right of the rotary knobs, is intended for the connection of standard USB sticks
and can be used for loading or saving sequences for the arbitrary generator, as well as for logging data. USB 2.0
sticks are well accepted, but must be
FAT32
formatted and should have a
maximum capacity of 32 GB
. USB 3.0
sticks are accepted as well, but not from all manufacturers.
All supported files must be held in a designated folder in the root path of the drive in order to be found. This fold-
er must be named
HMI_FILES
, such that a PC would recognize the path G:\HMI_FILES if the drive were to be
assigned the letter G.
The control panel of the device can read the following file types and names from an USB stick:
wave_u<your_text>.csv
wave_i<your_text>.csv
Function generator for an arbitrary function on voltage (U) or current (I)
The name must begin with
wave_u / wave_i
, the rest is user defined.
iu<your_text>.csv
IU table for the XY function generator.
The name must begin with
iu
, the rest can be user defined.
ui<your_text>.csv
UI table for the XY function generator.
The name must begin
with ui
, the rest can be user defined.
profile_<nr>.csv
Saved user profile. The number in the file name is a counter and not related to the
actual user profile number in the HMI. A max. of 10 files to select from is shown
when loading a user profile.
mpp_curve_<your_text>.csv User-defined curve data (100 voltage values) for mode MPP4 of the MPPT function
The control panel of the device can save the following file types and names to an USB stick:
battery_test_log_<nr>.csv
File with log data recorded from the battery test function. For a battery test log,
data different and/or additional to log data of normal logging is recorded. The <nr>
field in the file name is automatically counted up if equally named files already
exist in the folder.
usb_log_<nr>.csv
File with log data recorded during normal operation in all modes. The file layout
is identical to the those generated from the Logging feature in EA Power Control.
The <nr> field in the file name is automatically counted up if equally named files
already exist in the folder.
profile_<nr>.csv
Selected user profile. The number in the file name is a counter and not related to
the actual user profile number in the HMI.
wave_u_<nr>.csv
wave_i_<nr>.csv
Sequence point data of the arbitrary function generator, according to the cur-
rent selection of voltage (U) or current (I). Already existing files are listed and
can be overwritten.
mpp_result_<nr>.csv
Result data from mode MPP4 (MPPT function) with 100 sets of Umpp, Impp
and Pmpp
