Recommended warm-up time
Allow the device 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, 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
warm-up time.
Error codes
The UL returns -9999 when a value is out of range or an open connection is detected.
The UL 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
UL: cbFlashLED()
UL for .NET: FlashLED()
Causes the USB LED on a Measurement Computing USB module to blink.
When you have several modules connected to the computer, use these functions to identify a particular
