Programming example 10 OUTPUT 716; “:curr:ac:rang:auto:ulim 100e-3”
20 OUTPUT 716; “:curr:ac:rang:auto:llim 1e-3; ulim?; llim?”
30 ENTER 716; A$
40 PRINT A$
50 END
Line 10 Selects the 200mA AC range as the upper range limit.
Line 20 Selects the 2mA AC range as the lower range limit, and then queries the range limits.
Line 30 Addresses the Model 2001 to talk.
Line 40 Displays the upper and lower range limits (.2, .002).
