0-2MHz integrated measurement / with high-speed analog conversion |
CAN output option [CNT-723-CAN]
Outputs count values from CAN interface.
7.6μs high-speed analog output (±10V/±5V)
Calculation speed is within 3.5μs. High-speed response within 7.6μs from pulse input to isolation, calculation, D/A conversion, and analog output.

Full scale value of analog output can be freely set. Maximum ±47 bit count, for long time endurance test. |
Repeated measurement between two arbitrarily set values, such as 0 and 360. |
Enables measurement with expanded misalignment with respect to the target angle. For example, when stopping at 5°, the center value is set to 5° and the allowable value to the analog full scale value, and the measurement can be expanded between these values. This is ideal for detailed angle experiments. |

Reset / Z-reset
Zero reset and reset to any set value can be performed by button operation, reset signal, or EIA-574 (RS-232C).
Can be reset at the edge of Z-phase, etc., with no accumulated error.
Key lock
Prevents accidental operation. Safe for long-time endurance tests.
EIA-574 (RS-232C) communication
Count value reading/resetting and setting change.
