Checking the current’s minimum/maximum values

The current’s minimum/maximum setting values depend on the set current range. You can query the present minimum/maximum setting value by sending a query to which the MINimum or MAXimum parameter is added, as shown below.

:CURRent? MINimum

:CURRent? MAXimum
