4|INSTRUCTIONS FOR USE OMM 650UC
2.1 Description
The OMM 650UC model is a universal 6 digit programmable panel impulse counter/frequency meter/repeat/stop-watch.
The instrument is based on an 8-bit microprocessor, that secures high accuracy, stability and easy operation of the instru-
ment.
Measuring modes
COUNTER Single counter C-F
FREQUENCY Frequency C-F
STOP-WATCH Stop- Watch H
CLOCK Clock H
Programmable display projection
Calibration in „CM“ may be set the calibration coefficient
Projection -99999...999999 with fixed or floating DP in adjustable format 10/24/60
Time base 0,5/1/2/5/10/50 s
Digital filters
Input filter: the instrument allows to filter the input signal and thus suppress undesirable interfering
signals (e.g. relay back-swings). The set parameter indicates maximum possible measured
frequency, that the instrument will process, 5/40/100/200 Hz
Exponential average from 2...100 measurements
Radius of insensitiveness adjustable in digits
Functions
Preset initial non-zero value which is read always after instrument resetting
Rounding setting the projection step for the display
OM Link company interface for instrument operation, setting and update
External control
Hold display/instrument/menu access locking
Lock control keys lockin
Resetting resetting/presetting counter

INSTRUCTIONS FOR USE OMM 650UC |5
2.2 Operationn
The instrument is set and controlled by five control keys located on the front panel. All programmable settings of the instru-
ment are realized in two adjusting modes:
LIGHT Simple programming menu
- contains only items necessary for instrument setting and is protected by an optional numeral
code
PROFI Complete programming menu
- contains complete instrument menu and is protected by an optional numeral code
USER User programmable menu
- may contain arbitrary items selected from programmable menu (LIGHT/PROFI), which determines
the authorization (see or change)
- access is without password
All programmable parameters are stored in the EEPROM memory
(they hold even after the instrument is switched off).
Complete operation and setting of the instrument may be performed via communication interface
OM Link, which is a standard equipment of every instrument.
The operation program is freely available (www.orbit.merret.cz) and the only requirement is the
purchase of OML cable for connecting the instrument to PC. It is manufactured in version RS 232 and USB and is compatible
with all ORBIT MERRET instruments.
The OM LINK program version „Standard“ allows you to connect an unlimited number of instruments with the option of
visualizatiion and storage in PC.
2.3 Options
Comparators are assigned to control two limit values with relay output. The limits have adjustable hysteresis as well as
selectable delay of the switch-on. Reaching the preset limits is signalled by LED and simultaneously by the switch-on of the
relevant relay.
Time backup by RTC is designed for measuring mode „CLOCK“ and secures time measurement also when the instrument
is switched off (without projection on display).
2INSTRUMENT DESCRIPTION

6|INSTRUCTIONS FOR USE OMM 650UC
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..

input A
- setting applies for Input A
- setting the level (only for type PNP) of
input voltage, instrument subsequently
automatically selects the divider and thus
also the comparison levels
- range of setting 0…43 V (Input 1)
- range of setting 43…300 V (Input 2)
- table of comparison levels on page 7
Setting the level = 34 V Example

SCALE Setting the calibration
constant
- calibration constant is for the conversion of
input value to required display value
- by setting a minus value the direction of
counting is changed, i.e. we count down
- range: -0,00001...999999
