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.cz) 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 instruments. 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 visualiza-
tion and archiving in PC. The OM Link „Standard“ version has no limitation of the number of instruments connected.
2.3
Options
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 or DIN MessBus 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 (40 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 250 000 values may be stored in the instrument memory. Data transmis sion into PC via serial interface
RS232/485 and OM Link.
