1.9.6.4 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 3 to 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:

1.9.6.5 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 and tables for the XY generator, as well as for
logging data. USB 2.0 sticks are well accepted, but must be FAT32 formatted and have a maximum capacity of
32GB. 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 folder
must be named HMI_FILES, such that a PC would recognise the path G:\HMI_FILES if the drive were to be as-
signed the letter G.
The control panel of the device can read the following file types from a stick:
wave_u<arbitrary_text>.csv
wave_i<arbitrary_text>.csv
iu<arbitrary_text>.csv
ui<arbitrary_text>.csv
profile_<nr>.csv
mpp_curve_<arbitrary_
text>.csv
The control panel of the device can save the following file types to an USB stick:
battery_test_log_<nr>.csv
usb_log_<nr>.csv
profile_<nr>.csv
wave_u_<nr>.csv
wave_i_<nr>.csv
mpp_result_<nr>.csv

Sequence point table for an arbitrary function, either voltage (U) or current (I)
The name must begin with wave_u or wave_i, the rest is user defined.
IU table for the XY function generator.
The name must begin with iu, the rest can be user defined.
UI table for the XY function generator.
The name must begin with ui, the rest can be user defined.
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.
User-defined curve data (100 voltage values) for mode MPP4 of the MPPT function
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.
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.
Selected user profile. The number in the file name is a counter and not related to
the actual user profile number in the HMI.
Sequence point data of the arbitrary function generator, according to the current
selection of voltage (U) or current (I). Already existing files are listed and can be
overwritten.
Result data from mode MPP4 (MPPT function) with 100 sets of Umpp, Impp
