Description This command is used to manually select the measurement range
for the specified measurement function. The range is selected by
specifying the expected reading. The instrument will then go to the
most sensitive reading that will accommodate that reading. For
example, if you expect a reading of approximately 50mV, then simply
let <n> = 0.05 (or 50e-3) in order to select the 200mV range.
You can also use the UP and DOWN parameters to select range.
Each time UP or DOWN is sent, the next higher or lower measure
-
ment range is selected. When on the maximum range, sending UP is
a No-Op (no operation). When on the lowest range, sending DOWN
is a NO-Op.
Measurement ranges can instead be automatically selected by the
instrument. (See
“AUTO <b>,” page 18-42.)
