3. Local Control
The device RS 2x30 can be controlled locally using its display and keyboard. The content of the display
and the way the device is controlled depends on the current mode of the device.
Device modes:
•
basic mode
•
menu mode
•
graphical mode for displaying of harmonic parts
•
OPS Measurement Mode
•
special modes
The display in the
basic mode
shows values of measured and activated parameters. The way how the
information is displayed can be modified by the menu parameters. Each measured parameter can be
switched on or off for display. The maximum number of concurrently displayed measured parameters
on display is 7. When there are allowed to be displayed more than 7 measured parameters, there are
displayed on the top 7 measured parameters according to their priorities. To display the menu in the
basic mode press any key. For return to the basic mode quit the menu or the special mode you have
selected.
The
menu mode
is used to control the device from a cascade menu displayed on the screen of the
display. The measurement continues in the background while using menu mode. The only difference is
that the actual values of the measured parameters are not displayed to the user. The menu is used to
set parameters of the device and perform calibrations, tests etc. To display the menu in the basic mode
press any key.
The
graphical mode for displaying harmonic parts
can be activated only when the FFT signal
analyse module is attached. To enter this mode, press the DEL key in the basic mode. For return to the
basic mode press DEL, "ESC" or the OK key. This mode is designed for informative displaying of
amplitudes of the harmonic parts of measured voltages and currents. The bar on the right side of y-axis
is the amplitude of the 1
st
harmonic part. Next harmonic parts are displayed in the right direction. No. of
maximum frequency can be set in configuration menu. The background noise, if activated, is displayed
between the columns of the harmonic parts. Amplitudes of all of the harmonic parts are displayed in a
ratio scale related to first harmonic part. The amplitude of the first harmonic part is set to 1. All six
amplitudes of the input channels are displayed as three voltage/current pairs. Switching between the
displayed channels can be done pressing keys "LEFT" and "RIGHT". Change of the ratio scale on the
screen of the display can be done pressing the keys "UP" and "DOWN".
The
OPS Measurement Mode
is used to control Local Evaluation Unit OPS and measure error of
connected electricity meter. This mode can be selected from menu <Measurement / Energy / Impulse
/ OPS Meas> or with "EXP" key from the basic mode. To close this mode, press "ESC" or "EXP" button.
The basic activities of the device are not suspended
– device is measuring in background. Detailed
description of this mode is in chapter 5.9.1 Operation Modes.
Special modes
include calibration modes, test mode etc. The basic activities of the device are
suspended in these modes and the whole device is dedicated to the specific mode. To enter a specific
special mode, use the menu device modes. The way the device is controlled while working in the special
mode fully depends on the mode. The instructions shown on the screen and the description of the
specific mode in the manual explain the activities in special mode.
