Range and Measurement Rate Commands and Queries
The commands in Table 5-13 relate to ranging and measurement rates (i.e., readings/
second). In the autorange mode, the meter automatically selects a range for each reading;
in the manual range mode, the user selects a fixed range.
Table 5-13. Range and Measurement Rate Commands and Queries
Command Description
Causes the meter to enter the autoranging mode on the primary display. If the
autorange mode cannot be selected (e.g., if REL, dB, MN MX, or diode/continuity test
is selected), an Execution Error is generated.
Causes meter to return "1" if it is in autorange, or "0" if it is not.
Causes the meter to exit autoranging on the primary display and enter manual ranging.
The present range becomes the selected range.
Sets the primary display to the range designated by <range>. <range> is a number
between 1 and 7 that corresponds to a range shown in Tables 5-12A and 5-12B.
