If you require temperatures of 10 °C to 30 °C, either SENSOR SELECT setting (100 µA or 10 µA) will work with a 10K
thermistor. However, the 100 µA setting provides greater measurement resolution, and therefore better control.
NOTE - Generally, it is best to use the
100 µA SENSOR SELECT setting for all measurements of 10 °C or greater with
a typical 10 K thermistor.
Selecting and Using Thermistors
The type of thermistor you choose will depend primarily on the operating temperature range. These guidelines for
selecting the range and resolution will apply to any thermistor. From Figure B.1 you can see that 10 K thermistors are
generally a good choice for most laser diode applications where high stability is required near room temperatures.
Similarly, 10 K thermistors are often a good choice for detector cooling applications where you want to operate at
temperatures from -30°C to room temperature.
If you require a different temperature range or the accuracy you need can't be achieved with either switch setting,
select another thermistor. Thermistor temperature curves, supplied by the manufacture, show the resistance verses
temperature range for many other thermistors. ILX Lightwave Corporation will also offer help for your specific
application.
