Autotune PID is a sophisticated algorithm for optimizing the PID control parameters to your load. The 4-digit display shows actual or setpoint temperature or resistance, output current and voltage. An external analog setpoint input is via BNC on the rear panel (Analog version only). Even across ambient, this PID controller maintains precision temperature.įrom the front panel, adjust temperature limits, current limits, setpoint, PID control values, sensor calibration data, and enable or disable output current. Expect stability as good as 0.001☌ with thermistors. This instrument operates from AC (100-240V, 50 or 60Hz). Drive up to ±5 A to either thermoelectrics (TECs) or resistive heaters (RH) with up to 8 V compliance. The high-performance LFI3751 with Autotune PID temperature control instrument is now CE-compliant.
