2. 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.
INSTALLING THE BATTERY:
The battery compartment is located on the underside of the case, at the bottom
of the handle.
1. Open the battery compartment by sliding the lid back while pressing on the
release indent.
2. Ensure correct polarity, and push the battery in flush with the bottom board
until the connectors snap together on both sides.
3. Replace the battery compartment lid.

OFF FIRST. BATTERY REMOVAL WHILE THE METER IS ON MAY CAUSE

MEMORY. IF THIS OCCURS, CERTAIN FUNCTIONS (SUCH AS STATISTICS,

is removed by accident while the meter is ON, and if the readings already stored
