RANGE? IEEE-488 RS-232 Sequential Overlapped
This command returns the present DC voltage or current output range.
Parameter: <None>
Response: <value>
where <value> is one of the following:
V_0.1V DC volts, 100 mV range
V_1V DC volts, 1V range
V_10V DC volts, 10 V range
V_100V DC volts, 100 V range
A_0.1A DC current
NONE neither volts nor current is selected
Example: RANGE?
V_10V
This example indicates that the present output range is 10 V.
RANGELCK IEEE-488 RS-232 Sequential Overlapped
This command locks or unlocks the DC voltage output range per the present output
value.
Parameter: <value>
where <value> is one of the following:
ON to lock the present voltage range
OFF to unlock the present voltage range
Response: <None>
Example: RANGELCK ON
If the present DC voltage output is 5 V, this example locks the range at
10 VDC.
