Sensit®Gold CGI instruments are constructed of durable ABS
plastic to withstand the rigors of field use.
Incorporated in the hand grip area is the battery compartment.
All Sensit®Gold CGI instruments require 3 “C” type alkaline
batteries. APPROVED BATTERIES: PROCELL® MN 1400 bat-
teries or equivalent alkalines, PANASONIC HHR300CH or equiva-
lent NiMH (nickel metal hydride) batteries provide approximately
12 hours of use.  A tick adjust knob is located on the right side
of the instrument that activates the audible tick sound that helps
in locating the source of a gas leak. This tick is generated by
using specialized circuitry in combination with the LEL sensor
located at the end of the gooseneck assembly.

The tick can be easily heard with the speaker located in the
back of the instrument.

An infrared communication window is located on the right
side to allow the Sensit®Gold CGI instrument to download cali-
bration data, readings the operator has elected to save to the on
board memory, as well as communicate with the Smart-Cal Cali-
bration Station and PCI-2s computer interface.

A flexible gooseneck is used to assist  in locating the source
of gas leaks and remote sampling.  A water/dirt trap is located at
the end with a convenient luer style connector to attach sam-
pling and probe accessories.

A  two line display continuously updates the operator of all
available gas concentrations and alarms simultaneously as well
as  indicates internal functions such as air flow and battery power.
Below the display is a series of LEDs that are preset to indicate
combustible gas concentrations. The red LED on the right  side
will flash during any alarm condition.

There are 3 operational button pads on the front of all
Sensit®Gold CGI instruments.

• POWER/MUTE BUTTON (A): Operates POWER and MUTE
  features and exit menu items.
• BH TEST/MENU BUTTON (B): Operates a Bar Hole (BH) Test
   feature and to enter, change and select menu items.
• SAVE/ZERO BUTTON (C): Use for save data feature,
   manually zero sensors, scroll and change menu items.
