Example 13e. Query Last Scan Reading (U13) with Volts & No HLL Terminator
(1)
PRINT#1, “OUTPUT07;F0,0X Q1,0,0,0,0X”
(2)
PRINT#1, “OUTPUT07;C1-4,11X”
(3)
(Command lines to configure and start an acquisition.)
(4)
PRINT#1, “OUTPUT07;U13X”
(5)
PRINT#1, “ENTER07”
(6)
INPUT A$
+00.000.0000895 -00.000.0090865
The next example demonstrates how changing the channel type can effect the output of HLL queries. It
also shows the effect of specifying no HLL terminator; only one
ENTER
command returns all of the
HLL data. Notice that even though the data format was in Degrees Celsius (
°
C ) , the response is in
Volts since the channels were configured as such.
• Line 1: Set the data format to Degrees Celsius (
°
C ) with HLL terminator of
None
.
•
Line 2: Configure four channels – 1, 2, 3, and 4 – to Volts (despite the Degrees Celsius) in the
±
100 mV DC range.
•
Line 3: Provide the appropriate command lines to configure and start an acquisition.
•
Line 4: After an indiscriminate amount of time, query the Last channel readings.
•
Line 5: Get the response.
•
Line 6: The screen will show the Last readings for Channels 1 through 4.
Example 13f. Read Last Readings (R#) with HLL Terminator
(1)
PRINT#1, “OUTPUT07;F0,0 Q1,1,0,0,0X”
(2)
PRINT#1, “OUTPUT07;C1-4,1X”
(3)
(Command lines to configure and start an acquisition.)
(4)
PRINT#1, “OUTPUT07;R#2-3X”
(5)
PRINT#1, “ENTER07”
(6)
INPUT A$
+0250.60
(7)
PRINT#1, “ENTER07”
(8)
INPUT A$
-0049.50
The next example demonstrates how to retrieve Last readings for a subset of the configured channels.
Notice that since a HLL response terminator was specified, the Last reading for each channel had to be
entered separately.
•
Line 1: Set the data format to Degrees Celsius (
°
C ) with HLL terminator of CR LF / EOI.
•
Line 2: Configure four channels – 1, 2, 3, and 4 – with no setpoints.
•
Line 3: Provide the appropriate command lines to configure and start an acquisition.
•
Line 4: After an indiscriminate amount of time, query the Last readings for Channels 2 and 3.
•
Line 5: Get the response.
•
Line 6: The screen will show the Last reading for Channel 2.
•
Line 7: Get the next response.
•
Line 8: The screen will show the Last reading for Channel 3.
