User Saved Default Conditions
Each function of the Model 199 "remembers" the last
measurement cotiguration that it was set up for (such as
range, zero value, etc). Switchiig back and forth between
functions will not affect the unique configuration of each
function. However, the instrument will "forget" the con-
figurations on power-down unless they are saved (only one
instnnnent configuration can be saved).
Unique setup conditions can be saved by using SAVE
under Dh4M SETUl? or by sending device-dependent com-
mand Ll over the IEEE-488 bus. These user saved default
conditions will prevail over the factory default conditions
on power-up, or when a DCL or SDC~is asserted over the
bus.
IEEE Address and Line Frequency
Any IEEE address and line frequency setting can be saved
as default conditions by using the SAVE option under
DMM SETUP or by sending Ll over the bus. See para-
graph 2.7 for complete tionnation on using DMM SETUP
NOTE
An "UNCAL" error will set the IEEE address to
26 and the line frequency to 60H.z.
