Buffervar.dates - Keithley 3700A Series Reference Manual

Series 3700A System Switch/Multimeter Reference Manual

bufferVar.dates

When enabled by the bufferVar.collecttimestamps attribute, this attribute contains the dates (month, day,
and year) of readings stored in the reading buffer.
Type TSP-Link accessible
Attribute (R) Yes
Usage
dates = bufferVar.dates[N]
bufferVar
N
Details
The bufferVar.dates information from a reading buffer is only available if the
bufferVar.collecttimestamps attribute is set to 1 (default setting). If it is set to 0, you cannot
access any time information from a reading buffer. You may change the collect timestamps setting
when the buffer is empty (bufferVar.clear()).
This read-only attribute is an array (a Lua table) of strings indicating the date of the reading, formatted
in month, day, and year format.
Example
reset()
testData = dmm.makebuffer(1000)
testData.collecttimestamps = 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.dates[1])
printbuffer(1, 6, testData.dates)

This example creates a reading buffer named
testData, configures the buffer to collect
time and date data, sets and saves the DMM
configuration, creates a scan list, and then
runs the scan.
The print() command then outputs the first
measurement date.
Output:
07/11/2011
The printbuffer() command then outputs
the dates for measurements 1 to 6 in the
reading buffer.
Output:
07/11/2011, 07/11/2011,
07/11/2011, 07/11/2011,
07/11/2011, 07/11/2011
