2.INSTRUMENT DESCRIPTION
EXTERNAL CONTROL
Lock: control keys blocking
Hold: display/instrument blocking
Tare: tare activation/resetting tare to zero
Resetting MM: resetting min/max value
Memory: data storage into instrument memory
2.2 OPERATION
The instrument is set and controlled by five control keys located on the front panel. All programmable settings of the instrument
are performed in three adjusting modes:
LIGHT Simple programming menu
- contains solely items necessary for instrument setting and is protected by optional number code
PROFI Complete programming menu
- contains complete instrument menu and is protected by optional number code
USER User programming menu
- may contain arbitrary items selected from the programming menu (LIGHT/PROFI), which determine
the right (see or change)
- acces without password
All programmable parameters are stored in the EEPROM memory (they hold even after the instrument is switched off).
Complete instrument operation and setting may be performed via OM Link communication interface, which is a
standard equipment of all instruments.
The operation program is freely accessible (www.orbit.merret.eu) and the only requirement is the purchase of OML cable to
connect the instrument to PC. It is manufactured in version RS 232 and USB and is compatible with all ORBIT MERRET instru-
ments. Another option for connection is with the aid of data output RS 232 or RS 485 (without the need of the OML cable).
The program OM LINK in „Basic“ version will enable you to connect one instrument with the option of visualization and archiving
in PC. The OM Link „Standard“ version has no limitation of the number of instruments connected.
2.3 OPTIONS
Excitation is suitable for supplying power to sensors and transmitters. It has a galvanic separation.
Comparators are assigned to monitor one, two, three or four limit values with relay output. The user may select limits regime:
LIMIT/DOSING/FROM-TO. The limits have adjustable hysteresis within the full range of the display as well as selectable delay
of the switch-on in the range of 0…99,9 s. Reaching the preset limits is signalled by LED and simultaneously by the switch-on
of the relevant relay.
Data outputs are for their rate and accuracy suitable for transmission of the measured data for further projection or directly into
the control systems. We offer an isolated RS232 and RS485 with the ASCII, MESSBUS, MODBUS - RTU or PROFIBUS protocol.
Analog outputs will find their place in applications where further evaluating or processing of measured data is required in
external devices. We offer universal analog output with the option of selection of the type of output - voltage/current. The value
of analog output corresponds with the displayed data and its type and range are selectable in Menu.
Measured data record is an internal time control of data collection. It is suitable where it is necessary to register measured
values. Two modes may be used. FAST is designed for fast storage (100 records/s) of all measured values up to 8 000 records.
Second mode is RTC, where data record is governed by Real Time with data storage in a selected time segment and cycle. Up to
266 000 values may be stored in the instrument memory. Data transmis sion into PC via serial interface RS232/485 and OM Link.

3. INSTRUMENT CONNECTION
The instrument supply leads should not be in proximity of the incoming low-potential signals.
Contactors, motors with larger input power should not be in proximity of the instrument.
The leads into the instrument input (measured quantity) should be in sufficient distance from all power leads and appliances.
Provided this cannot be secured it is necessary to use shielded leads with connection to ground (bracket E).
The instruments are tested in compliance with standards for use in industrial area, yet we recommend to abide by the above
mentioned principles.
