1.3 The XGF868i keypad
Keypad program
Along with the 2-line, 16-character LCD, the XGF868i
includes a 6-key magnetic keypad. The decal cutout for
each key contains a hall effect sensor, pushbutton switch
and visible red LED. The magnetic wand used to activate a
magnetic key is found attached to the meter chassis below
the front panel. An operator activates the key by pressing
the magnetic wand up to the glass lid over the desired key.
The LED will light indicating a successful key press.
NOTE: The pushbutton switch will also act as a key press
but is done with the glass lid open. Do not use the
pushbutton switch in a hazardous area where the lid
needs to be installed.
Use the magnetic keypad to navigate through the user
program. The menu map may be followed in sequence,
or the four arrow keys may be used to scroll through the
prompt screens. Figure 1 shows the front of the XGF868i,
with magnetic keypad and magnetic wand.

IMPORTANT
The XGF868i keypad enables programming of the
instrument through the glass faceplate without removing
the cover. Thus, all programming procedures may be
performed while the unit is installed in a hazardous area.
Six keys on the keypad enable users to program
the XGF868i:
• [Enter] - confirms choice of a specific option and
data entry within the option
• [Escape] - allows users to exit from a specific option
without entering unconfirmed data
• [

] and [

] - enable users to highlight a specific
window in the display option or to scroll through a list
of options (parameters, letters, and numbers 0-9 as well
as the negative sign and decimal point) in a menu
• [

] and [

] - enable users to scroll to a specific
option, among choices in an option, or to a character
in a text entry.
When you power up the XGF868i, the display first shows the
model and software version:
The meter then starts to display measured parameters.
To enter the keypad program , press the [escape] key,
followed by the [enter] key, and the [escape] key again.
Each successive key must be entered within 10 seconds of
the prior key.
As a guide in following the programming instructions in
this chapter, the relevant portions of the XGF868i menu
map have been reproduced in Figure 28 on page 40 and
Figure 29 on page 41 . Proceed to the following sections to
enter data in the channel or globl menus.
IMPORTANT
If the keypad has not been pressed for 10 minutes,
the XGF868i exits the keypad program and returns
to displaying measurements. The meter retains any
configuration changes that were confirmed with the
[enter] key, and restarts as if the operator had completed
the programming cycle.
