Upon power up, or after receiving a DCL or SDC command, the instrument will
go to the 2oOn-W range (Rl).
The range command gives the user control over the sensitivity of the instrument.
The Fl through Fll commands perform essentially the same functions as the front
panel RANGE buttons.
An added feature available over the bus is autorange for the volts, amps and
coulombs functions. When FO is sent over the bus, autorange is selected. The range
that the instrument goes to depends on the programmed value that is sent with
a value command (V). The instrument will go to the lowest range (for best resolu-
tion) that can accomodate the value sent over the bus. Sending F12 over the bus
disables autorange without affecting the present range.
1. The instrument can be placed in autorange (RO) while on the ohms function.
However, since value commands are not recognized by the ohms function, RO
has no affect on ohms range selection.
2. Sending Rl through Rll also disables autorange and places the instrument on
the range that corresponds to that command option.
