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:
Voltage,
OVP, UVD, OVD,
U-min, U-max
Min.
Nominal Incre-
ment
80 V 4 0.01 V
250 V 5 0.01 V
500 V 4 0.1 V
750 V 4 0.1 V
1000 V 5 0.1 V
1500 V 5 0.1 V
In manual operation every set value can be set in the increments given above. In this case
the actual input 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). It can be used to upload or download sequences for the arbitrary or value tables for the UI-IU
function generator
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 electronic load can read the following file types from a flash drive:
wave_u<arbitrary_text>.csv
wave_i<arbitrary_text>.csv
iu<arbitrary_text>.csv
ui<arbitrary_text>.csv
