Required Configuration
Although most of the user-defined configuration states have associated defaults, the TempScan/1100 or
MultiScan/1200 does not scan its channels on the initial power-up activation. Before scans can begin,
the following required configurations must be performed:
•
Configuration of the desired channels . See command Channel Configuration (
C
).
• Configuration of the scan. See commands Channel Configuration (
C
) and Set Scan Interval (
I
).
•
Configuration of the acquisition. See command Set Counts (
Y
).
•
Configuration of the Trigger and Stop events. See command Set Trigger Configuration (
T
).
After these steps are completed and scanning begins, the alarms and the High/Low/Last Registers are
updated at the programmed scan rate, and the scans are placed in the Acquisition Buffer.

INPUT A$
The above command lines illustrates all of the required configurations:
•
Line 1: Configure channels 1 to 4 with Type J thermocouples.
•
Line 2: Configure the normal scan interval to 1 minute and the acquisition scan interval to 1
second.
•
Line 3: Set the Pre-Trigger scan count to 100 and the Post-Trigger scan count to 1000.
•
Line 4: Configure the Trigger (trigger start event) to the software Trigger On (
@
) command and
the Stop (trigger stop event) to the Post-Trigger Count. The front panel TRIGGER LED indicator
should flash.
•
Line 5: Trigger the acquisition. Acquisition scans should now be collected until 1000 Post-
Trigger scans have been collected. The front panel TRIGGER LED indicator should be on.
Querying the High/Low/Last Registers shows the temperature values for the configured channels.
•
Line 6: Query HLL registers for the configured channels.
•
Line 7: Get the response.
•
Line 8: The screen will show the temperature data for the four channels.
