Temperature Data Reporting
FOT Lab Kit User’s Manual 5-3
Error Reporting The FOT Lab Kit device has a very simple error reporting
mechanism. If a problem is detected the letters "PE" (Probe Error)
are inserted into the serial data stream following the data for the
affected channel(s).
This error could be caused by a number of factors including, but not
limited to:
1. Probe not attached to input
2. Improper probe type
3. Damaged probe
4. Input channel is not properly calibrated
5. Temperature of target is outside the device's measurement
range
6. One or more inappropriate parameter settings
7. Failure of the capture hardware
When an error is detected on a given input channel the format
includes the "PE" message as in the following example showing an
error on channel 2:
1: 224.39 C 2: 224.51PE 3: 224.22 C 4: 224.19 C
Analog Output
Data
The FOT Lab Kit includes a 0-10 volt analog output for each
installed input channel. The analog outputs may be enabled and
disabled using the AE command. The output voltage may be scaled
using the AS and AO commands. Using these two commands you
may scale the analog output to the working temperature range of
your application.
When the instrument is in Standby mode the analog outputs are set
to 0.00V. In Standard mode with analog outputs enabled (AE
command) the outputs will track the measured temperature based
upon the parameters set through the AS and AO commands. By
properly scaling the outputs you can obtain optimal resolution
throughout the selected temperature range.
