2.5.4 Manual Measurement Mode
The primary difference between automatic and manual mode is that in manual mode the
phases of the test cycle must be initiated manually by the user. Here there are three
phases rather than the four in automatic, the dwell function would be part of the charge
phase. The results would still be displayed in a manner indicated above, the mode would
indicate manual rather than automatic. Default and other stored setups can still be
recalled, the only difference being that the test cycle times are not applicable.

Menu Functions
2.6.1 General
All programmable functions of the 1865 are controlled by easy to use menu displays. The
user enters the menu mode by selecting the [MENU] key which calls up three top level
menus, Setup, I/O and Utilities. Each one of these is comprised of a sub menu list whose
functions are described in detail below. Finding ones way around the menu listing is
accomplished in a fashion similar to an Automatic Teller Machine (ATM) using the up,
down, right and left arrow keys as indicated on the adjacent LCD display. A highlighted
menu function can be controlled by selecting the [ENTER] key, making the desired entry
or selection and pressing [ENTER] again to implement.
