1.9.6.4 Resolution of the displayed values
In the display, set values can be adjusted in variable 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:

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.
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 flash
drives (flash drive). This can be used for:
•
Loading or saving sequences for the arbitrary and loading tables for the UI-IU function generator
•
Updating HMI firmware (new languages, functions)
USB flash drives must be
FAT32
formatted and have a
maximum capacity of 32GB
. 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 flash drive:
*.bin
Firmware updates only for the control panel
. The file name format is given like
96230058_FW-BE1_V204.bin, listed in short form as FW-BE1_V204.bin. Other
files won’t be recognised or listed.
wave_u<arbitrary_text>.csv
wave_i<arbitrary_text>.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.
iu<arbitrary_text>.csv
IU table for the XY function generator.
The name must begin with
iu
, the rest can be user defined.
ui<arbitrary_text>.csv
UI table for the XY function generator.
The name must begin
with ui
, the rest can be user defined.
pv<arbitrary>.csv
PV (photovoltaics) table for XY the function generator.
The name must begin with
pv
, the rest can be user defined.
fc<arbitrary>.csv
FC (fuel cell) table for the XY function generator.
The name must begin with
fc
, the rest can be user defined.
