Whenrelative offset is enabled, all subsequent measured readings are offset by the value that is set for thiscommand.You can set this value, or have the instrument acquire a value. If the instrument acquires the value,read this setting to return the value that was measured internally.If you have math, limits, or filter operations selected, you can set the relative offset value to includethe adjustments made by these operations. To include these operations, setsmu.measure.rel.level to smu.measure.read(). The adjustments from these operations arenot used if you use the smu.measure.rel.acquire() function to set the relative offset level.Examplesmu.measure.func = smu.FUNC_DC_CURRENTsmu.measure.rel.level = smu.measure.read()smu.measure.rel.enable = smu.ONSets the measurement function to current,performs a current measurement, uses it asthe relative offset value, and enables therelative offset for current measurements.Also seeRelative offset (on page 3-79)smu.measure.rel.acquire() (on page 8-169)smu.measure.rel.enable (on page 8-170)
