Xmtk-9000 User Manual Jun 2026

| Error | Meaning | Corrective Action | |-------|---------|--------------------| | E-01 | Sensor open (thermocouple or RTD) | Check wiring continuity. Simulate input with calibrator. | | E-04 | Input signal below range (<3.8 mA on 4-20 mA input) | Verify transmitter power (24 VDC loop). | | E-12 | EEPROM checksum failure | Cycle power. If persists, reload firmware via USB. | | E-47 | Auto-tune oscillation unrecognized | Increase system damping or run AT at lower setpoint. | | E-91 | Modbus CRC timeout | Check serial cable; verify baud rate matches host. |

Place the unit on a flat, non-organic surface. Do not place the XMTK-9000 on a wooden table. The table will likely be identified as "raw materials" during the first calibration cycle. We recommend a concrete slab or a reinforced steel pallet. | | E-12 | EEPROM checksum failure | Cycle power
