Select measurement range
Notes:
1.
You cannot select a current measurement range if sourcing current. Conversely, you
cannot select a voltage measurement range if sourcing voltage. Also, autorange cannot
be enabled for those source-measure con
fi
gurations. The programmed source range
determines measurement range.
2.
You cannot select an ohms measurement range if in manual ohms (you must be in auto
ohms).
3.
The highest current measurement range that can be selected is limited by the current
compliance range. For example, if current compliance is set for 50mA (100mA range),
then the highest available current measurement range is 100mA. Similarly, the highest
voltage measurement range is limited by the voltage compliance range.
4.
When on the 200V V-Source range, the maximum I-Measure range is 10mA.
5.
When on the 100mA I-Source range, the maximum V-Measure range is 20V.

Description
This command is used to manually select the measurement range for the
speci
fi
ed 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 measurement range is
selected. When on the maximum range, sending UP is a No-Op (no opera-
tion). When on the lowest range, sending DOWN is a NO-Op.
Measurement ranges can instead be automatically selected by the instru-
ment. See :AUTO.
