GENERAL DESCRIPTION
The SENSIT® HXG-3P is designed to detect combustible gases. All
SENSIT® HXG-3P instruments incorporate an advanced low power
semiconductor sensor to measure combustible gases in LEL (Lower
Explosive Limit) range.
LEL resolution can be factory set between 0.1% and 2%. The ppm display
is simultaneously shown in 1 or 10ppm increments (resolution). If enabled,
the peak reading display takes precedence over the ppm display.
An automatically backlit display shows all gas concentrations being
measured. LEDs located on the front of the instrument indicate preset
visual warnings of increased gas concentration.
Audible and visual alarms warn the operator of hazardous conditions
being sensed. The preset alarms are indicated by a red ashing LED,
display indicator and alarm sound. The combustible gas alarm is preset
from 50% LEL (2.5% methane, 1.1% propane or 0.75% pentane).
The SENSIT® HXG-3P instrument is approved for the ATEX Directive
EN60079-0:2004 & EN60079-11:2007 when used with Duracell™

Duracell PC1400 batteries provide approximately 12 hours of
continuous use.
A thumbwheel is located on the right side of the instrument to activate
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.
The Infrared Communication window is located on the right side to allow
the SENSIT® HXG-3P instrument to
1. Communicate with Smart-Cal Calibration Station.
2. Communicate with IR-Link Computer Interface.
3. Download calibration data
4. Download readings the operator has elected
to save to the instrument’s on-board memory.
9
PRODUCT FEATURES
A exible gooseneck is used to assist in locating the source of gas leaks
and remote sampling.
A two line display continuously updates the operator of all available
gas concentrations and alarms simultaneously as well as indicates low
battery power.
Below the display is a series of LEDs that are preset to indicate
combustible gas concentrations. During an alarm condition the red
Hazard 3 LED will ash and an audible warning will sound.
There are 3 operational button pads on the front of all SENSIT® HXG-3P
instruments.
BUTTON (A) POWER/MUTE
Operates POWER and MUTE features and exit menu items.
BUTTON (B) MENU

SENSOR TYPE
Combustible Gas Sensor
All SENSIT® HXG-3P instruments incorporate a highly sensitive
semiconductor type sensor. The function and accuracy of the sensor are
monitored and controlled by specialized circuitry and a microprocessor.
This sensor is capable of measuring concentrations of 1ppm or 10ppm
of methane (natural), propane or pentane gas up to 100% LEL.
The Pump
The instrument is equipped with a powerful and efcient pump. A water/
dirt lter incorporated in the sensor cap at the end of the gooseneck
protects the pump and other internal components. An additional internal
lter protects the pump if the external lter is missing or damaged.
Audible and visual indicators alert for insufcient ow conditions
NOTE: Operating the instrument without a sensor cap or with an altered
or damaged cap and/or lters can cause damage to the instrument and
void the warranty.
11
BATTERY INSTALLATION/REPLACEMENT
⚠ CAUTION: Always change batteries in an environment free of
combustible gases.
⚠ Warning: Do not mix batteries of different type or age.
Battery replacement is necessary when the display reads BAT LOW,
an audible alarm sounds and the green ready LED ashes. When the
instrument remains in BAT LOW, a countdown will appear starting at 300
seconds (5 minutes) which is the maximum time remaining to shutdown.
Remove the battery sleeve cover by removing the battery sleeve screw
with a T-8 screwdriver. Depress the locking tab on the front of the handle
with a coin or at object and pull the battery sleeve handle away from the
top or display area of the instrument.
Place 3 approved batteries into the battery holder. For best results hold
the battery compartment so that it lays in one hand. With the other hand
install the battery that goes toward the front rst, the battery that is in
contact with the rear spring second and nally insert the third battery in
the center by forcing the second battery such that the spring compresses
and allows the batteries to go into place.
If you do not use your hand to hold the bottom of the battery compartment
the batteries can come out. Observe the polarity markings on the inside
of the battery holder for proper battery installation. Improper installation
will cause the instrument not to operate. Replace the battery sleeve and
allow the locking tab to snap into position. Replace the battery sleeve
retaining screw.
NOTE: Improper battery installation will disable the instrument.
Check to be sure the handle is secure to the instrument body by gently
pulling the handle away. The handle will remain rmly in place if a proper
connection is made.
12

instrument will clear the PK% reading.
⚠ CAUTION: Always start any SENSIT® HXG-3 in a gas free
environment to insure a proper zero.
6. When testing high areas or overhead lines the use of the optional
extension adapter will allow a broom handle or painters stick to extend the
instrument to the area where sensing must be accomplished. This slides
onto the battery sleeve and is held in place by the locking nut assembly.
14
OPERATION AND USE
7. When a gas is sensed the display will update. Additionally, a series
of LEDs on the front of the instrument will illuminate when the preset
concentrations of the calibration gas are reached. If an alarm condition
exists, based on a preset alarm point, the red (HAZ 3) LED will ash and
the alarm will sound.
The preset levels of the LED warning lights are:
Amber LED/Low 5 - 9.9% LEL
Red LED/Haz1 10.0 - 24.9% LEL
Red LED/Haz2 25.0 - 49.9% LEL
Red LED/Haz3 50.0 - 100% LEL
8. During an alarm condition (factory default at 50% LEL) the display
will ash, red (HAZ 3) LED will ash and an audible alarm will sound
indicating a potentially unsafe environment. To disable the audible alarm
press and release the POWER/MUTE button (A). To enable the alarm
press and release it again.
9. To assist in locating the source of small combustible gas leaks or
surveying areas outdoors or indoors, rotate the thumbwheel located on
the right side of the instrument until a steady ticking sound is heard.
Note: There is no warm-up for this feature as it uses the LEL sensor that
is already operating.
Move the sensor toward the area suspected of leakage. As the sensor
moves closer to a leak source the tick will increase. When the tick
becomes a steady tone rotate the thumbwheel in a clockwise direction
while keeping the sensor in the same position.
Continued on next page.
15
OPERATION AND USE
Continued from previous page.
This will slow down the tick and allow the operator to nd a higher
concentration using the same procedure. If the tick goes away you have
moved away from the leak or there is no more gas present.
For best results always use the leak detector prior to using any liquid
leak detection uids as these sensors will detect their presence.
10. At any time the operator may save the readings on the display by
pressing the SAVE/ZERO button (C). This will save all readings for
download at a later time.
The memory is factory set to store 6 events. This can be adjusted from
1-100 at the factory. The most recent save is rst during download.
11. Following Federal, State, Municipal and/or Company procedures
move to the areas where gas readings are suspected or must be tested.
During sampling the respective readings may change. Audible and
visual alarms will activate when the preset limits are reached.
12. When being used in dark areas an automatic backlight will illuminate
the display.
13. To turn instrument off, press and hold the POWER/MUTE button (A)
for 5-6 seconds until POWER DOWN appears on the display.
16
CALIBRATION CHECK
To verify the accuracy of any SENSIT® HXG-3P, it must be exposed
to a known concentration of test gas. Any sensor that does not meet the
specications listed in this manual may require calibration or replacement.
A calibration check does not update the calibration due date. Full
calibration is required to update this feature.
