DKM-411 User Manual Rev_01 Firmware V-1.0
K46D03-EN - 40 -
The unit measures a large number of electrical parameters. The display of the parameters is organized as
PARAMETER GROUPS and items in a group.
Navigation between different groups are made with and buttons.
Each depression of the button will cause the display to switch to the next group of parameters.
After the last group the display will switch to the first group.
Each depression of the button will cause the display to switch to the previous group of
parameters. After the first group the display will switch to the last group.
Navigation inside the same group is made with and buttons.
Each depression of the button will cause the display to switch to the next parameter in the same
group. After the last parameter the display will switch to the first parameter.
Each depression of the button will cause the display to switch to the previous parameter in the
same group. After the first parameter the display will switch to the last parameter.
Below is a basic list of parameter groups:
Digital measurements: Voltages, currents, frequency, kW, kVA, kVAr, pf etc... Per phase and
total/average measurements are available.
Scopemeter Display: This group display waveforms of voltages and currents as an oscilloscope. All Ph-
N and Ph-Ph voltages as well as phase currents are available.
Displays offer 3-color graphics for the visualization of all phases together, or 2-color display for V-I pairs,
allowing investigations per phase. This feature is especially useful to investigate waveform distortions due
to harmonic loads.
Graphical Harmonic Analysis Results: This group displays harmonic composition of voltages and
currents as bar_graphs, until the harmonic 31 (due to screen resolution limitations). Analysis of all Ph-N
and Ph-Ph voltages as well as phase currents are available.
Displays offer 3-color graphics for the visualization of all phases together, or 2-color display for V-I pairs,
allowing investigations per phase. This feature is especially useful to investigate harmonics caused by
complex loads.
Numerical Harmonic Analysis Results: This group displays harmonic composition of voltages and
currents with 0.1% resolution. All Ph-N and Ph-Ph voltages as well as phase currents are available. This
feature is especially useful to investigate the harmonic effects caused by complex loads.
Phasor Diagram Display: This screen shows both graphically and digitally the angle relation between
voltage and currents.
Analog Metering Display: This group displays various measured parameters as analog displays, 6
displays at once. Different combinations of per-phase or total values are available.
Compare Display: This group has 2 analog displays, with freely selectable channels for each one. The
relation between 2 measured parameter may be visualized in an easy-to-see form.
Counters Display: This group shows various incremental power counters recorded in the unit.
Analog Clock Display: Shows date & time in an analog format. Provides also some system information
screens and the company logo screen which is displayed at power-on.
Demand/Min/Max Display: This group shows current and power demand records, minimum recorded
values of voltages, currents, frequency and power parameters and maximum recorded values of voltages,
currents, frequency and power parameters.
User Screens: This group includes 4 display screens that may be freely configured by the user. Any
display screen can be defined as the default screen. Thus the unit may be customized in a way to display
only the required parametersy only necessary information to the user.
Alarm Display: This group displays all existing alarms, one screen per alarm. When there is no more
alarm to di
splay it will show “END OF ALARM LIST”.
