Send the following commands for this example application:
--Reset the instrument to the default settings.
reset()
--Set the measure function to DC voltage.
dmm.measure.func = dmm.FUNC_DC_VOLTAGE
--Set the measurement range to 10 V.
dmm.measure.range = 10
--Set the number of power line cycles to 10.
dmm.measure.nplc = 10
--Set the input impedance to auto so it selects 10 Gohm for the 10 V range.
dmm.measure.inputimpedance = dmm.IMPEDANCE_AUTO
--Enable autozero.
dmm.measure.autozero.enable = dmm.ON
--Set the averaging filter type to repeating.
dmm.measure.filter.type = dmm.FILTER_REPEAT_AVG
--Set filter count to 100.
dmm.measure.filter.count = 100
--Enable the filter.
dmm.measure.filter.enable = dmm.ON
--Read the voltage value.
print(dmm.measure.read())
