dmm.digitize.read()
This function makes digitize measurements, places them in a reading buffer, and returns the last reading.
Type TSP-Link accessible Affected by Where saved Default value
Function Yes
Usage
reading = dmm.digitize.read()
reading = dmm.digitize.read( bufferName )
reading The last reading of the measurement process
bufferName The name of the reading buffer, which may be a default buffer (
defbuffer1
or
defbuffer2
) or a user-defined buffer; if nothing is specified, the reading is stored
in
defbuffer1

Details
You must set the instrument to make digitize measurements before sending this command.
This command initiates measurements using the present function setting, stores the readings in a
reading buffer, and returns the last reading.
This command makes the number of digitize measurements that is set by the
dmm.digitize.count
attribute.
When you use a reading buffer with a command or action that makes multiple readings, all readings
are available in the reading buffer. However, only the last reading is returned as a reading with the
command.
If you define a specific reading buffer, the reading buffer must exist before you make the
measurement.
Example
voltMeasBuffer = buffer.make(10000)
dmm.digitize.func =
dmm.FUNC_DIGITIZE_VOLTAGE
print(dmm.digitize.read(voltMeasBuffer))
Create a buffer named
voltMeasBuffer
. Set
the instrument to measure voltage.
Make a measurement that is stored in the
voltMeasBuffer
and is also printed.
