1.9.6.4 Resolution of the displayed values
In the display, set values can be adjusted in xed 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:
Voltage,
OVP, UVD, OVD,
U-min, U-max
Current,
OCP, UCD, OCD,
I-min, I-max
Power,

1.9.6.5 USB port (front side)
The frontal USB port, located above 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 and 3.0 sticks are well supported. The stick must be FAT32 formatted. All supported les must be held in a desig-
nated folder in the root path of the USB stick in order to be found. This folder 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. Subfolders are supported. In case there
are multiple les of the same type, e. g. such starting with “wave”, the device will list the 20 rst it can nd.
The control panel of the device can read the following le types and names from a stick:
File name Description Section
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 dened.
3.10.10.1
prole_<arbitrary_text>.csv Previously saved user prole. A max. of 10 les to select from is shown
when loading a user prole.
3.9
mpp_curve_<arbitrary_text>.csv User-dened curve data (100 voltage values) for mode MPP4 of the
MPPT function
3.10.14.5
iu<arbitrary_text>.csv IU table for the XY function generator.
The name must begin with iu , the rest can be user dened.
3.10.12
The control panel of the device can save the following le types and names to a USB stick:
File name Description Section
usb_log_<nr>.csv File with log data recorded during normal operation in all modes. The le
layout is identical to the those generated from the Logging feature in EA
Power Control. The <nr> eld in the le name is automatically counted
up if equally named les already exist in the folder.
3.4.8
prole_<nr>.csv Saved user prole. The number in the le name is a counter and not
related to the actual user prole number in the HMI. A max. of 10 les to
select from is shown when loading a user prole.
3.9
wave_u<nr>.csv
wave_i<nr>.csv
Sequence point data (here: sequences) of either voltage U or current I
from arbitrary function generator
3.10.10.1
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 log-
ging is recorded.
3.10.13.5
mpp_result_<nr>.csv Result data from MPP tracking mode 4 in form of a table with 100 data
groups (Umpp, Impp, Pmpp)
