Section 7: SCPI command reference Series 2280 Precision DC Power Supply Reference Manual

7-68 077085503 / March 2019

When you read this setting, you see the measurement range that the instrument is presently using. If

you change the range while the output is off, the instrument does not update the hardware settings,

but if you read the range setting, the return is the setting that will be used when the output is turned

on. If you set a range while the output is on, the new setting takes effect immediately. When you

assign a specific value to this command, the instrument is set on a fixed range that is large enough to

measure the assigned value. The instrument selects the best range for measuring a value of

<range>.

For example, for current measurements, if you expect a reading of approximately 50 mA, set

<range> to 0.05 (or 50e-3) to select the 100 mA range.

For concurrent measurements, range only applies to current measurement. For voltage

measurement, there is only one range.

Example

:SENS:CURR:RANG 0.01

Select the 10 mA range.

:SENS:CONC:RANG 1

Select the 1 A range.

:SENS:VOLT:RANG 32

Select the 32V range.
