Features

Auto-tuning (AT)-

*RAMP and Soak

 - Build in 1 segment of RAMP and SOAK function.

*Approval and Free Power

 - All WT models get CE approval. Operate on any voltage from AC 85~265V at 50/60Hz. DC24V is also available.(*Optional Function)

*High Accuracy

  - Input with 14 bit A/D resolution, 0.2% accuracy of FS. Build in Auto Zero- Auto Span function to keep good accuracy.

*Data Lock Function

  - All parameters are separated in 3 operation levels. Each parameter can be hidden or locked to prevent unauthorized changes.

*Modbus Communication (Optional Function)

  - WT series sport both Modbus RTU and MODBUS ASCII protocol.

* Heater Break Alarm (HBA)(Optional Function)

  - Heater current flowing through CT can be displayed on controller.
