Value 
a
a. This column is applied to the auto ranging or the limited auto ranging. For fixed ranging, maximum mea-
surement value is Range column value.
Measurement Resolutions 
b
b. Measurement resolution depends on the integration time setting. For Knob sweep measurement, see the 
column of Integration Time 80 μs to 560 μs.
