CYDAS UDR Library User’s Guide Analog Input Boards - UCDAS TEMP, UCDAS TC

Recommended warm up time (UCDAS TEMP only)

Allow the UCDAS TEMP to warm up for 30 minutes before taking measurements. This warm up time

minimizes thermal drift and achieves the specified rated accuracy of measurements.

For RTD or thermistor measurements, this warm-up time is also required to stabilize the internal current

reference.

Calibration

Any time the sensor category is changed in the configuration for the UCDAS TEMP, a calibration is

automatically performed by InstaCal. If the device has not been warmed up when this occurs, you should re-

calibrate after the specified warmup time.

Error codes

 The UDR Library returns -9999 when a value is out of range or an open connection is detected.

 The UDR Library returns -9000 when the device is not ready. This usually occurs right after the device is

powered up and calibration factors are being loaded.

Miscellaneous functions and methods supported
