OPERATING INSTRUCTIONS
-USER GUIDE-
This guide provides step-by-step instructions on powering up, using and powering down
the meter.
NAVIGATION:
The meter uses an on-screen, menu-driven approach to navigate through the meter
features, allowing for an intuitive understanding of keypad functions. Each screen
presents the user with a number of selectable options. One of the options is always
selected and the user can move (navigate) the selection to any other available option.
The keypad is aimed at providing navigational control, and not at accessing specific
features. There are four directional keys aligned intuitively around a middle (fifth) key
(see Figure 1): Above (UP), below (DOWN), to the right (RIGHT) and to the left (LEFT).
The middle key is used to SELECT the option highlighted on the screen. For purposes
of this owner’s manual, the five keys will be referred to as and SELECT.
