Note: Alarm settings are stored on the device, and can only be changed though InstaCal.
Temperature measurements can be stored on a CompactFlash memory card (64 MB CF card included with hardware). Each sample is stored on the card as a binary file. You set up the following logging options through InstaCal:
InstaCal provides further options for copying, converting, and deleting the binary files. You can access log data stored on the memory card with a CompactFlash reader, or by transferring the files from InstaCal to a computer for processing and conversion using the USB bus.
Note: A card reader is not required to access log data on a device installed with firmware 3.0 and later. A device with this firmware version appears in Windows Explorer as a removable drive from which you can directly access the log data.
Due to processing limitations, data logging to the memory card is not allowed when the device is connected to an active USB bus on the computer. When operating as a data logger, disconnect the USB cable from the computer, and connect the external power supply shipped with the device.
Note: When using a self-powered hub, make sure it is attached to the PC USB port before connecting it to a USB-5200 Series device. If a powered hub is connected to the device first, it may be detected by the device as a power supply and go into logging mode.
USB-5200 Series devices provide eight independent temperature alarms. Each alarm controls an associated digital I/O channel as an alarm output. The input to each alarm is one of the temperature input channels. Use InstaCal to set up the temperature conditions used to activate an alarm, and the output state of the channel when activated (active high or low).
Digital channels that are configured as alarms will power up in an output state. When an alarm is activated, the associated DIO channel is driven to the output state defined by the alarm configuration.
The alarms function both in data logging mode and while attached to the USB port on a computer. The alarm configurations are stored in non-volatile memory on the device and are loaded on power up.
The internal update rate for temperature measurement is a fixed value for these devices. If the UL reads the device faster than the internal update rate, temperature readings "repeat." For example, if using cbTIn()/TIn() 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.
When using single sensors for RTD or thermistor sensors, ignore the data for channels that do not have sensors attached. It is best to use cbTIn()/TIn()/t_in() for these configurations, since you can select the channels to read. If you use cbTInScan()/TInScan()/t_in_scan(), 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.
Specify the NOSCALE option to retrieve raw data in volts or resistance from the device. When NOSCALE is specified, calibrated data is returned, although a cold junction compensation (CJC) correction factor is not applied to the returned values.
InstaCal allows you to save device configuration settings to a file, or to load a configuration from a previously saved file.
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 and thermistor measurements, this warm-up time is also required to stabilize the internal current reference.
Any time you change the sensor category for the USB-5203, calibration is automatically performed by InstaCal. If the device is not warmed up when this occurs, calibrate the device again after the specified warm-up time.
