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.
Adjustable resolution and display formats for the touch panel display:
Voltage,
OVP, UVD, OVD,
U-min, U-max
Current,
OCP, UCD, OCD,
I-min, I-max
Power,

In manual operation every set value can be set in the increments given above. In this case
the actual output values set by the device will lie within percentage tolerances as shown in the
technical data sheets. These will influence the actual values.

USB port (front side)
The frontal USB port, located to the right of the rotary knobs, is intended to host standard USB sticks and can be
used for loading or saving sequences for the arbitrary generator, as well as for data recording.
USB 2.0 sticks are accepted and must be
FAT32
formatted and have a
maximum capacity of 32GB
. 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 and names from an USB stick:
profile_<nr>.csv
Previously 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 an user profile.
wave_u<arbitrary>.csv
wave_i<arbitrary>.csv
Function generator arbitrary function for voltage (U) or current (I)
The name must begin with
wave_u / wave_i
, the rest is user defined.
The control panel of the device can save the following file types and names to an USB stick:
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 an user profile.
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.
wave_u<nr>.csv
wave_i<nr>.csv
Function generator for an arbitrary function, 99 sequence points of either voltage
(U) or current (I)
