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.

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 the XY generator, as well as for recording
measured data during running operation.
USB 2.0 sticks are accepted and must be
FAT32
formatted and have a
maximum capacity of 32 GB
. USB 3.0
sticks also work, but not from all manufacturers. All supported files must be held in a designated folder in the root
path of the USB 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 assigned 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
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.
profile_<arbitrary_text>.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_<arbitrary_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 to an USB stick:
usb_log_<nr>.csv
File with log data recorded during normal operation in all modes. The file lay
-
out 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
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.
wave_u<nr>.csv
wave_i<nr>.csv
Sequence point data (here: sequences) of either voltage U or current I from
arbitrary function generator
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 USB logging is recorded.
The <nr> field in the file name is automatically counted up if equally named
files already exist in the folder.
mpp_result_<nr>.csv
Result data from MPP tracking mode 4 in form of a table with 100 data groups
(Umpp, Impp, Pmpp)
