1. APPLICATION
The N100 meter is a programmable digital instrument designed
for the measurement of 3-phase, 3 and 4-wire power network para-
meters in balanced or unbalanced systems. The measured values
are displayed on a two-color LED display. The meter enables control
and optimization of the power electronic devices, systems and industrial
installations.
The meter provides measurement of: RMS of voltage and current,
active, reactive and apparent power, active, reactive and apparent
energy, power factors, frequency, the harmonics of current and voltage
/up to 51st/, THD of voltage and current, averaged active
and apparent power P Demand, S Demand, averaged current I Demand
/15, 30 or 60 minutes/. Voltages and currents are multiplied by gi-
ven voltage and current ratios of the measuring transformers.
Power and energy indications take into account all programmed ratio
values. The value of each measured value can be transmitted
to the master system via the RS-485 or Ethernet interface. Three relay
outputs signal the overow of the chosen value, and the pulse output
can be used for the consumption check of 3-phase active energy.
The programmable analog outputs map the assigned parameter.
The pulse input can be used to check the counters with the pulse outputs.
There is a galvanic separation between following units of the meter:
–supply
–voltage inputs
–current inputs
–RS485 interface
–Ethernet interface
–pulse input
–pulse output OC
–alarm outputs
–analog outputs

of the EN 61010-1 standard.
Comments concerning safety:
• The meter should be installed and connected only by a qualied
personnel. All relevant safety measures should be observed during
installation.
• Always check the connections before turning the meter on.
• Prior to taking the meter housing off, always turn the supply off
and disconnect the measuring circuits.
• Removal of the meter housing during the warranty period voids
the warranty.
• This meter conforms to all requirements of the electromagnetic
compatibility in the industrial environment.
• A switch or a circuit-breaker should be installed in the building
or facility. It should be located near the device, easily accessible
by the operator, and suitably marked.

5. METER DESCRIPTION
5.1 Current inputs
All current inputs are galvanically isolated (internal current transformers).
The meter is adapted to work with external measuring current transfor-
mers / 1 A or 5 A /. Displayed current values and derivative values are
automatically converted in relation to the introduced external current
transformer ratio.
5.2 Voltage inputs
All voltage inputs are galvanically isolated (internal transformers).
Values on voltage inputs are automatically converted according
to the introduced ratio of the external voltage transformer. Voltage inputs
are specied in the order as 3x57.7/100V, 3x230/400V or 3x400/690V.
5.3 External connection diagrams
External connections are shown in Figures 2 and 3.

The N100 meter has 6 buttons, 4 4½-digit display sections, illuminated
symbols and unit parameters. The values of the measured parame-
ters are shown on the active pages selected by subsequent pressing
the button (next page) or (previous page).
The page consists any 4 values selected from the Table 1 and displayed
simultaneously on the meter. The page denition is described
in the conguration mode P.

The assignment of individual buttons is as follows:
The button allows to enter the procedure SEt (pressed for more
than 3 seconds) when programming is used to accept the entered value.
The buttons when programming are used to change
the value of the digit in the decimal position. They enable to display
the minimum and maximum values respectively in the measurement mode.
The buttons enable to change the pages
in the measurement mode, when programming enable a cursor displa-
cement to successive decimal positions, in the procedure SEt enable to
change the displays luminosity.
The button enables in anytime the resignation of carried out
operations or return to a higher level in the procedure SEt.
It cancels the alarms in measurement mode.

and displays the N100 meter name, version and current software version
where:
N100 – meter type,
230V 5A – version

6.4 MEASURING mode
In the MEASURING mode the values are displayed according
to the pages that are preset at the factory or congured by the user
in Pages Programming PAG.
Changing the page is done by pressing the button
or . The sequence of displayed pages is according to a table
created in PAG mode.
Preview of the maximum or minimum values respectively is
done while the button or is pressed down.
Reset of maximum or minimum values is done by pressing the button
while viewing their values, i.e. rst the button or
and then must be pressed.
Alarms are active if they were allocated. Note that the alarms do not
need to be associated with the values displayed on the page because
the change of a page would result in action on two-state outputs.
The alarm switching on is signaled by the lighting of the ALn inscrip-
tion (n=1..3). The end of alarm duration at the alarm signalization latch
switched on, is indicated by the pulsation of the ALn inscription (n= 1..3).
Erasing alarm signalization latch / if it was set in the Alarm parameters
mode ALn / is done by pressing the button .
When displaying the reactive capacity power or energy, a marker indi-
cating the load character is displayed , there is no mark for inductive
load.
When displaying the active power, the sign „-” is displayed for active
energy export or no mark for active energy import.
Exceeding of the upper or lower indication range is signaled
on the display by upper or lower horizontal lines. For measurement
of the averaged values (P Demand, S Demand, I Demand) single
measurements are carried out with 0.25 second quantum.Averaging time
to choose from: 15, 30 or 60 minutes. Until all samples of the averaged
values are acquired, the values are calculated from already measured samples.
Current value in the neutral wire I(N) is calculated from phase current vectors.

6.4.1 Measurement of voltage and current harmonics
The choice of harmonics is done by pressing the buttons
forviewingthecurrentharmonicsor
for voltage harmonics.
Voltage harmonics U1, U2, U3 or current harmonics I1, I2, I3
are displayed simultaneously for 3-phases. The number of displayed
harmonic circled in the gure, is signaled by blinking and it can
be changed in the range 2..51 by pressing or buttons.
By pressing button, you can return to the measuring mode.
