Description
These commands are used to set the upper and lower limits for LIMIT 1 and LIMIT 2. The actual
limit depends on which measurement function is currently selected. For example, a limit value
of 1 is 1V for the volts functions (DCV or ACV), 1A for the current functions (DCI or ACI), 1 Ω
on the ohms functions ( Ω 2 or Ω 4), and 1° (C, F or K) for the temperature function (TEMP). The
upper limit value is not range sensitive. An upper limit of 2 for DCV is 2V on all measurement
ranges. Note that limit tests cannot be performed on frequency (FREQ) measurements.
Programming example
10 OUTPUT 716; “:calc3:lim:upp 10; upp?”
20 ENTER 716; A$
30 PRINT A$
40 END
