Usage
unitsOfMeasure = bufferVar.units[N]
unitsOfMeasure
The units of measure stored with the readings
bufferVar
The reading buffer
N
The reading number (1 to bufferVar.n)
Details
This attribute is an array (Lua table) of the strings that indicate the unit of measure that is stored with
readings in the buffer. You can designate units as one of the following: Volts AC, Volts DC, Amps AC,
Amps DC, dB VAC, dB VDC, Ohms 2wire, Ohms 4wire, Ohms ComSide, Fahrenheit, Kelvin, Celsius,
Hertz, Seconds, and Continuity.
Example
reset()
testData = dmm.makebuffer(1000)
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.units[1])
printbuffer(1, 6, testData.units)
This example creates a reading buffer
named testData, sets and saves the DMM
configuration, creates a scan list, and then
runs the scan.
The print() command outputs the units of
the first reading in the reading buffer.
Output:
Volts DC
The printbuffer() command outputs the
units of readings 1 to 6 in the reading buffer.
Output:
Volts DC, Volts DC, Volts DC,
Volts DC, Volts DC, Volts DC
