CHANGE NOTICE
MODEL 4lOA PICOAMMETER
INTRODUCTION: Since Keithley Instruments is continually improving pro-
duct performance and reliability, it is often necessary to make changes
to Instruction Manuals to reflect these improvements. Also, errors in
Instruction Manuals occasionally occur that require changes. Sometimes,
due to printing lead time and shipping requirements, we can't get these
changes immediately into printed Manuals. The following new change in-
formation is supplied as a supplement to this Manual in order to provide
the user with the latest improvements and corrections in the shortest
possible time. Many users will transfer this change information directly
to a Manual to minimize user error. All changes or additions are indi-
cated in italics.
