GENERAL DESCRIPTION:
Simply stable temperature control. Wire your
thermoelectric cooler and thermistor to the
board with the cable provided. Add the
appropriate DC power supply and indicate the
expected 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
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.
