SIGTRONICS’ EGT 101 INSTALLATION INSTRUCTIONS

The Sigtronics’ EGT 101 Digital Exhaust Gas
Temperature meter is designed for mounting in the
conventional 2.25” instrument panel cutout. Parts
Supplied: 4 ea. mounting screws, power supply cable,
back-lighting kit.

BACK LIGHTING KIT - Prior to mounting the EGT,
determine the aircraft’s electrical system voltage. Then
select the proper voltage lam p from the backlighting kit.
The kit consists of a lam p socket and two wedge base
incandescent lamps.

ELECTRICAL CONNECTIONS

For 12V electrical s ystems, install the #73 lamp into
the lamp socket. A 24V system requires the #85 lamp.
(The lamp identification numbers appear on the bulb’s
glass envelope).

Install the lamp/socket assem bly into the hole on the
rear of the instrum ent case by inser ting and rotati ng 1/8
turn clockwise.
