Page 12: Product Overview
This is achieved by modulating the current through a thermoelectric load and continuously monitoring the feedback signal generated from a thermistor temperature sensor. The linear output stage of the LDT-5412B offers the low current noise necessary to achieve the temperature stability required in most low- noise and frequency-stabilized laser applications. -

GAIN: A single turn potentiometer which adjusts the control loop gain. This adjustment affects the slew rate and settling time of the LDT-5412B when reaching the desired setpoint. If the GAIN is set too low (counter-clockwise,) the LDT-5412B will take longer to reach the desired setpoint. If the GAIN is set too high (clockwise,) the LDT-5412B may oscillate around the desired setpoint. -

(linearized mode) of the thermistor, the SET LED when illuminated displays the set point resistance or temperature (linearized mode), and when the TE CURRENT LED is illuminated the LDT-5412B will display the actual measured TEC current. Error Indicators TEC OPEN: Indicates that the thermoelectric voltage exceeds the rated compliance voltage of the instrument. -
Page 19: Output Off/On Button
The OUTPUT off/on switch is located in the lower right-hand corner of the front panel. This switch has a toggling action which turns the output current of the LDT-5412B off and on. When the output is active, the LED indicator just above the switch will be lit. -

ILX Lightwave Application Note #2, Selecting and Using Thermistors for Temperature Control. Figure 2.3 Thermistor Temperature Range Temperature from Resistance The LDT-5412B Thermoelectric Temperature Controller primarily displays resistance of the thermistor; several methods can be used to convert the resistance to a temperature. - Page 22 Linearized Thermistor Mode – For users wanting to display a calculated temperature without using one of the methods above the LDT-5412B has a unique mode that when selected will display and control to a calculated temperature. To use this mode the LDT-5412B sensor select switch must be set to °C LINEARIZED FOR 10k.
