Keypad Program
Along with the 2-line, 16-character LCD, the XGM868i 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 14 shows the front of the XGM868i, with
magnetic keypad and magnetic wand.

The XGM868i’s keypad enables programming of the instrument through the glass faceplate without
