Xmtk-9000 User Manual Today

For thermocouples, use a precision millivolt source at 0°C and 50°C reference.

Use free software like ModPoll. Request device ID 1, register 40001. A valid reply confirms communication. If timeout occurs, verify wiring (A to A, B to B, GND to GND).

The XMTK-9000 includes 4 MB of internal flash memory – enough for approximately 500,000 logged readings.

The XMTK-9000 acts as a Modbus slave device. Connect your PLC or SCADA to the COM terminal (A+, B-). xmtk-9000 user manual

Register Map (Excerpt): | Address | Parameter | Data Type | | :--- | :--- | :--- | | 40001 | Zone 1 PV (x10) | Signed 16-bit | | 40002 | Zone 1 SV (x10) | Signed 16-bit | | 40003 | Zone 1 Output % (0–1000) | Unsigned 16-bit | | 40100 | Alarm Status (Bitmask) | Unsigned 16-bit | For thermocouples, use a precision millivolt source at

Pro tip: For real-time monitoring, poll at 10Hz max to avoid bus contention.

When you first energize the XMTK-9000, the screen will cycle through a self-test sequence. Follow this XMTK-9000 user manual procedure:

  • Input sensor type: Scroll to match your physical sensor (e.g., K-CA for K-type thermocouple, Pt100 for RTD, 4-20 for current loop).
  • Date and time: Set in YYYY-MM-DD HH:MM:SS format. The internal supercapacitor retains time for 72 hours without power.

    • After confirmation, the main operation screen appears: PV (Process Value) in large digits, SV (Set Value) in smaller digits below. Use free software like ModPoll

    | Error Code | Meaning | Solution | | :--- | :--- | :--- | | E-101 | TC Open (Thermocouple broken) | Check continuity. Replace probe. | | E-204 | Output short circuit | Remove load from OUT 1/2. Maximum 3A. | | E-309 | Modbus CRC mismatch | Check wiring (A/B polarity). Reduce baud rate. | | E-412 | Auto-tune failed (timeout) | System cannot reach setpoint in 60 min. Check heater power. | | E-500 | Internal NVRAM corrupt | Perform factory reset: Power + hold "Clear" for 10s. |
