Datakom DV-0101 User manual

These state-of-the-art panel meters are designed for
accurate measurement of the AC RMS voltages and
frequency in single-phase and three-phase systems.
Although they are mainly used in electrical panels ,
these devices can also be integrated in many other
applications.
Devices have separate inputs for supply and
measurement with common neutral point.
Changing Display Selection:
By using the MENU button, L1-N, L2-N, L3-N, L1-
L2, L2-L3, L3-L1 voltages and frequency can be
selected and read from display. Every depression on
the MENU button will display the next
measurement.
60 seconds after the last keypress, the display will
return automatically to the default display mode.
However the defult display mode is selectable by
programming.
Any measured parameter can be set as the default
display. Automatic parameter scrolling is also
provided. The selection is stored into a non-volatile
memory and is not affected from power failures.

Do not open the unit. There is no serviceable parts
inside.
Fuses must be connected to the power supply and
phase voltage inputs, in close proximity of the unit.
Fuses must be of fast type (FF) with a maximum
rating of 6A.
Disconnect all power before working on equipment .
When the unit is connected to the network do not
touch terminals.
Do not try to clean the device with solvent or the
like. Only clean with a dry cloth.
Verify correct terminal connections before applying
power.
Electrical equipment should be serviced only by
competent service personnel. No responsibility is
assured by the manufacturer or any of its
subsidiaries for any consequences arising out of the
use of this material.
Only for front panel flush mounting.
Before installation
Read the user manual carefully, determine the
correct connection diagram.
Remove all connectors and mounting brackets from
the unit, then pass the unit through the mounting
opening.
Put mounting brackets and tighten. Do not tighten
too much, this can brake the enclosure.
Make electrical connections with connectors
removed from sockets, then place connectors to
their sockets.
Note that the power supply terminal is separated
from measurement terminals, with common neutral
point.
Failure to follow below
instructions will result in
death or serious injury
