Usage
reading = bufferVar.formattedreadings[N]
reading
Buffer reading formatted as it appears on the front-panel display for element N
bufferVar
The name of the reading buffer, which may be a default buffer (defbuffer1 or
defbuffer2
) or a user-defined buffer
N
The reading number N; can be any value from 1 to the number of readings in the
buffer; use the bufferVar.n
command to determine the number of readings in the
buffer
Details
This attribute outputs an array (a Lua table) of strings that contain the stored readings. The readings
are shown as they would appear on the front-panel display.
Example
reset()
testData = buffer.make(50)
trigger.model.load("SimpleLoop", 3, 0, testData)
trigger.model.initiate()
waitcomplete()
print(testData.formattedreadings[1])
printbuffer(1, testData.n,
testData.formattedreadings)
Create a reading buffer named
testData, configure the
instrument to make three
measurements, and store the
readings in the buffer.
Print the first reading formatted as
it appears on the front-panel
display.
Example output:
+00.0028 nA
Print all readings in the reading
buffer as they appear on the
front-panel display.
Example output:
+00.0028 nA, +00.0039 nA,
+00.0040 nA
