SPECIFICATIONS
Accuracy:(Timer) Crystal time base,
± 2 PPM/degrees Celsius from zero to fifty degrees Celsius. Totalizer accuracy ± 1 digit. Tachometer accuracy ± digit, ± 1 X 10.5 time base accuracy.
Display:
6 1/2 digits. .56" high efficiency red LED ± 1999999. Decimal points are user programmable.
Controls:
Front panel start, stop and reset pushbutton switches which are also used to set limits and multiplier.
Remote Inputs:
Start/stop and reset signals: require closure to logic common or TTL logic zero. Input loading one LPTTL load. Can also be used to set limits and multiplier.
Outputs:
ASCII RS232 compatible: (optional) ASCII RS422 compatible: (optional) Programmable baud rates. Baud Rates: 300, 1200, 9600.
Limit Outputs:
TTL compatible output can be programmed to go high or low at limit and hold until reset. Will drive 4 TTL loads. Limits are set by putting unit in setup mode and then toggling through numbers.
