Add the appropriate DC power supply and indicate the input voltage on the jumper. With the output disabled, adjust the on-board 12-turn trimpot and watch the setpoint temperature change on the 4-digit display. Switch to Actual temperature and display your thermistor temperature. Watch the LED tree to see “over/under temperature” or “stable at setpoint” status. Enable the output current and watch the temperature quickly lock in on the setpoint.

The green LED on the In-Range indicator lights when actual temperature is within 0.05°C of the setpoint. If the actual temperature exceeds the setpoint, the upper LED will light. If it is below the setpoint temperature, the lower LED will light.

The WTC3293-14001 has been designed to work with various thermoelectrics driving up to ±2.2 Amps. It operates with +7 V, +9 V, or +12 V input voltage
