Hardware considerations
Pacing temperature readings
The internal update rate for temperature measurement is a fixed value for these devices. If the UDR Library
reads the device faster than the internal update rate, temperature readings "repeat." For example, if using
cbTIn() in a loop to measure a rapidly changing temperature, readings do not change for several iterations of
the loop, then “jump” when the update occurs internally.
Using single sensors with cbTInScan()
When using single sensors for RTD or thermistor sensors, you should ignore the data for channels that do not
have sensors attached. It is best to use cbTIn() for these configurations, since you can select which channels to
read. If you use cbTInScan(), however, data for all channels over the entire range of channels are returned.
Since some channels are not populated in this configuration, you should filter out the data for channels
without sensors.
Saving configuration settings
InstaCal allows you to save UCDAS TEMP and UCDAS TC configuration settings to a file or load a
configuration from a previously saved file.
 Each UCDAS TEMP channel can be configured to measure temperature data collected by one of five
categories of temperature sensors: thermistors, thermocouples, RTDs, semiconductors, and Disabled.
 Each UCDAS TC channel can be configured to measure temperature data collected by one of eight types
of thermocouples.
