OM 602UQC
The OM 601UQC is a universal 6 digit panel programmable impulse counter/frequency meter/repeat/ evaluation of signals from IRC sensors and stopwatch/clock.
The instrument is based on an 8-bit microcontroller with logic array, which secures high accuracy, stability and easy operation of the instrument.
Technical data

| Number of inputs | 2 | ||||||||||
| Temperature coeficient | 50 ppm/°C | ||||||||||
| Accuracy | ±0,01% of the value + digit (for frequency - depends on selected time of measuring) | ||||||||||
| Type of input | Upon contact, TTL, NPN/PNP with the posibility to set the comparative levels in the instrument's menu:
|
||||||||||
| Mode |
|
||||||||||
| Presetting | -99999…999999 Initial non-zero value which is set each time when the instruemnt is re-set |
||||||||||
| Calibration constant | -0,00001…999999 Multiplication constant used to convert the number of pulses do desired projection value |
||||||||||
| Filtration constant | 0 / 10 / 20 / 45 / 55 / 65 / 100 / 200 / 500 / 1 000 / 2 000 Hz Used to filter out interfering signals (pollution). Entered value sets the maximum possible frequency the instrument can process without limitations. |

| Type of sign projection | 14-segment LED |
| Number of signs | 6 |
| Digit height | 14 mm |
| Display color | Red Green |
| Decimal point | Selectable in the menu or floating |
| Brightness | Selectable in the menu |
| Measuring units | Last two symbols can be used to display units relating to the measured value |
| Instrument configuration | The instrument contains two independ channels (input values, state of counter / input frequency A / B), which can further be filtered and used for mathematical operations. | ||||
| Input filter | The instrument has the capability of filtering polluting elements out of the input signal ant reduce "false signals". Filtration is done by the method of sampling. |
||||
| Digital filters | Exponential average: from 2 .. 100 measurements N-th value: 2 .. 100 Radius of insensitivity: band of suppression of change of the measured value Rounding: setting the projection step for display |
||||
| Mathematic functions | Mathematical operations between channels A and B: +, -, *, /, (A-B)/B Polynomial, Inversion polynomial, Logarithm |
||||
| Maximum and minimum | The channel of min. and max. receives both min. and max. values either from the instrument's power-on, or from its re-set until the next re-set. The min and max values can be used to control peripherals. | ||||
| Tare | Zeroing the display at non-zero input signal | ||||
| Other functions | Summation: Used in production shift environment. When the display is zeroed, the count from the last shift is added to the previous counts. | ||||
| Data backup | In the event of a power failure the data is stored into an EEPROM memory. | ||||
| Time backup | Time back up (for mode Stopwatch (timer) /Clock) | ||||
