Features:
* Model: MTTU2-6E1R-M485 Microsecond Timer with RS485 Communication Interface
* Relay Alarm Output: 1 relay output for alarm control
* Display: Single-row digital LED display for clear, easy-to-read measurements
* Auxiliary Power Supply: Built-in 12V DC output for powering sensors
* Precise Microsecond Timing: Designed for accurately measuring microsecond-level pulse widths and time intervals
* Stable and Reliable Performance: Excellent resistance to electrical interference and vibration for dependable operation
* Communication Interfaces: Supports RS485/RS232 interfaces
* Communication Protocol: Modbus protocol
* Baud Rate: 9600bit/s (default)
* Multiple Timing Applications: Suitable for single-pulse timing and dual-pulse interval measurement

Technical Specifications:
* Relay Alarm Output: One relay output
* Timing Range: 0-999999 units
* Time Units: 0.1µs, 1µs, 10µs, 100µs, 1ms
* Accuracy: Maximum resolution of 1µs; minimum measurable time interval ≥ 5µs
* Input Signal Voltage: Low level ≤ 2V; high level ≥ 6V
* Input Impedance: ≥ 4.7kΩ

Three Timing Modes:
1. CP1 Falling Edge to CP2 Falling Edge: Timing starts at the falling edge of the CP1 input signal and stops at the falling edge of the CP2 input signal. The instrument records the time interval between the two falling edges.
2. CP1 Pulse Width Measurement: Timing starts at the falling edge of the CP1 input signal and stops at its rising edge. The instrument measures the pulse width of CP1. The CP2 input is not used in this mode.
3. CP1 Pulse Interval Measurement: Timing starts at the falling edge of the first CP1 input pulse and stops at the falling edge of the second CP1 input pulse. The instrument records the time interval between two CP1 pulses. Three consecutive pulses on CP1 are not permitted. The CP2 input is not used in this mode.

Two Display Modes:
1. Elapsed Time Display: Displays the measured time interval.
2. Reciprocal Time Display: Displays the reciprocal of the measured time interval, representing the instantaneous speed value.

Note:
* For reliable communication, a three-wire connection is recommended. In addition to the two communication lines, A (D+) and B (D-), an extra 0V reference wire should be connected between the tester's 0V terminal and the communication interface's 0V (GND) terminal. This connection helps prevent damage to the communication chip caused by voltage differences between the tester and the communication interface. It also helps reduce electrical interference and improve communication stability.
