Example
reset()
testData = dmm.makebuffer(1000)
testData.collectchannels = 1
dmm.nplc = 0.5
dmm.range = 0
dmm.configure.set("Dcv_100mV")
dmm.setconfig("slot2", "Dcv_100mV")
scan.create("2035:2040")
scan.execute(testData)
print(testData.channels[1])
printbuffer(1, 6, testData.channels)
This example creates a reading buffer named
testData, configures the buffer to collect
channel data, sets and saves the DMM
configuration, creates a scan list, and then
runs the scan.
The print() command then outputs the first
measurement channel.
Output:
2035+
The printbuffer() command then outputs
the channels for measurements 1 to 6 in the
reading buffer.
Output:
2035+, 2036+, 2037+, 2038+, 2039+,
2040+
