2. Device Description
2.1 Introduction
The Reference Standard is the single-phase (RS 2110) and three-phase (RS 2310) version of
precision meter for electrical power and energy measurement.
The Reference Standard is designed to meet all requirements put on a reference standard in a
single- and three-phase electricity meter testing and calibration systems. The Reference Standard can
be set to any real or artificial mode of operation in three phase system and is capable to evaluate the
individual quantities per phase and the three-phase cumulative quantities as well.
The Reference Standard is based on precision 24-bit A/D conversion and digital signal processing
technology enabling accurate evaluation of all main and informative quantities. Beyond measurement
of all kinds of power, voltage, current and phase, the meter measures the harmonic content and
distortion of the input signals.
The Reference Standard has independent input circuits for the individual phases. This feature in
combination with the possibility to assign the impulse output to any combination of the input channels
(phases) enablesfor example to use the device in one phase system while the free channels can gather
additional information like power consumption of the current and voltage circuits for contact error
monitoring.
The Reference Standard makes harmonic analyze of the voltage and current spectrum and
measures and computes these quantities shown in display of the device:

2.4 Connecting of the Device
The three phase version of the device is equipped with three independent channels L1, L2, L3. Each of
them has two inputs: Current input (CURRENT) and voltage input (VOLTAGE). The inputs are insulated
from each other; therefor its connection is arbitrary. The basic connection of the voltage and current
clamps (only for one channel) for indicating of positive power (energy) is shown on the
Figure 1.
The benefit of this connection is that its own input current of the voltage input of the device does not
load the current input of the device. The measurement error caused by the volt drop on the current
clamps is negligible due to use of electronically compensated current transformer in the current input.
Figure 1
The inner ground of the electronic circuits connected to the GND clamp is common for both analogue
and digital circuits. The input voltage clamps Lo and Hi are in a differential connection against the GND,
i.e. the device measures the voltage difference between the clamps Lo and Hi. Each of the Lo and Hi
clamps can be loaded by operating voltage up to 500V against the GND clamp.
The positive orientation of the voltage difference is defined as Uhi - ULo.
The positive orientation of the current is from the clamp In to the clamp Out.
The lowest error caused by the finite symmetry of the potential input circuits can be reached by
connecting the neutral wire (or the wire with the lowest voltage against the guard wire) to the Lo input
clamps and the phase wires to the Hi clamps. The inner ground of the device, that is GND clamp, is
connected to the safety ground i.e. to zero voltage.
When connecting the device as an independent measuring device without connecting of the
communication channels, there is no grounding connected from the outside power supply. In this case
it is appropriate to connect the inner ground with the lowest potential by connecting the GND clamp with
the Case/Earth clamp and thus to the guard wire in the socket outlet.

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 1st 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"keyfrom 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.

3.1 Manual Control
The menu is composed of a number of cascade levels. One of the levels is shown on the following
figure:
The name of the menu level is shown in the first row of the display (The top level is called MAIN MENU
and all the other levels have their names set according to their contents).
Items of the specific menu are shown in the rows below the menu label. The maximal number of items
shown in a single menu screen is determined by the number of function keys (F1, F2 ... F6) on the
keyboard of the device. Each menu item is labelled by the assigned function key, followed by the name
of the menu item and in the right part of the menu there is a possible value of the menu item.
Types of the menu items:
•submenu - the label ends with characters ... - by choosing this menu item you enter a lower level
of the menu. Selected submenus are protected by a password, what is typical for the calibration
submenu.
•command - the label ends with special characters and the right part of the menu lebel is empty - by
choosing this menu item a specific command is executed.
•parameter - the label doesn't end with special characters and the right part of the menu label
contains a value - choosing this item menu the current value of the specified parameter can be
changed.
3.1.1 Menu Entering Keys
If the device appears in a basic state, the menu can be entered using:
OK - enter the main level and first item highlighting
F1, F2... - enter the basic menu level with immediate item selection which
is attached to key used (i.e. in accordance with a type of the given item,
immediate switch to the lower level, or immediate execution of the instruction, or
immediate editing of the parameter value will happen, respectively),
1, 2... - enter intothe mainmenu level and item highlight with a given sequence number,
another key - enter into the main level and first item highlight.
