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 and can have 3 or 5 digits. Related 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 inuence 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 ash
drives (ash drive). This can be used for:
• Loading or saving sequences for the arbitrary and loading tables for the UI-IU function generator
• Updating HMI rmware (new languages, functions)
USB ash drives must be FAT32 formatted and have a maximum capacity of 32GB. All supported les 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 electronic load can read the following le types from a ash drive:
*.bin Firmware updates only for the control panel. The le name format is given like
96230058_FW-BE1_V204.bin, listed in short form as FW-BE1_V204.bin. Other
les won’t be recognised or listed.
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 dened.
iu<arbitrary>.csv IU table for the XY function generator.
The name must begin with iu, the rest can be user dened.
ui<arbitrary>.csv UI table for the XY function generator.
The name must begin with ui, the rest can be user dened.
pv<arbitrary>.csv PV (photovoltaics) table for XY the function generator.
The name must begin with pv, the rest can be user dened.
fc<arbitrary>.csv FC (fuel cell) table for the XY function generator.
The name must begin with fc, the rest can be user dened.
