WARNING: The Snifit+ contains a lithium battery
which my leak or explode if improperly used. Do
not place the Snifit

IMPORTANT: Snifit+ has no user-serviceable
parts inside. Do not disassemble the instrument.

IMPORTANT: Verify operation each day by per­forming a functional (bump) test.

IMPORTANT: Keep all openings free of dirt,
debris, and foreign objects.

IMPORTANT: Do not use if damaged or improp­erly operating. Contact a service representative
immediately.

DESCRIPTION

The Snifit+ is a rugged personal gas monitor for detecting
carbon monoxide gas. Preset alarms provide visual, audi­ble, and vibration alerts for low and high alarm conditions.
Built-in time weighted average (TWA) alarms and short­term exposure limit (STEL) alarms provide an even greater
margin of safety for the user. A custom display provides
easy-to-view information including:

• gas concentration

• time remaining (months) until replacement is needed

• battery low alert

• calibration activation.

FEATURES

Construction: The Snifit+ is constructed of durable ABS

plastic. The top housing is further protected with a shock
absorbing material to protect the Snifit
field use. The unit is sealed for an IP65 environmental
resistance rating.

Operation: Two buttons operate the Snifit

The audible (sound), visual (LEDs), and vibrating alarms are
sequenced during alarms. The alarm settings are defined
during the set-up of the instrument. The instrument’s
default alarm limits are factory-preset to the values shown
below:

Extended Range Operation: All readings from 1000 ppm
to 2000 ppm are displayed as “_10%” to “_19%”. The
underscore represents a decimal point. Levels detected
above “_19%” display “OL”.

FEATURES (CONTINUED)

LOW: 35 ppm TWA: 50 ppm
HIGH: 200 ppm STEL: 75 ppm

Sensor: The sensor opening is on the front of the Snifit+ .

STARTUP

Press to start the Snifit+ in an area known to be CO gas
free and with normal oxygen content. The following will
display as a normal start up sequence.

1. All segments and icons will activate.

2. Gas type to be sensed will be displayed.

Mounting: The instrument may be attached using the
metal lanyard loop or the sturdy suspender clip on the
back of the instrument.

Alarm Components: The front of the instrument has an
opening for the audible alarm (which is sealed to maintain
the integrity of the IP65 rating). Multiple LEDs beneath
the frosted area create a visual warning that is bright even
in sunlight.

NOTE: The Snifit+ cannot be powered off or
zeroed when in alarm mode.

Alarm Limits: The Snifit+ has two basic styles of alarm:

• Low Alarms: Indicators activate at 2 sec intervals

• High Alarms: Indicators activate at 1 sec intervals.

3. Software version is shown.

4. Temperature in °C is shown.

5. Alarms will sound, illuminate and vibrate.

6. “LO” Low alarm setpoint displays.

7. “HI” High alarm setpoint displays.

8. “tA” TWA alarm setpoint displays (if applicable).

9. “StL” STEL alarm setpoint displays (if applicable).

10. “Sn” Serial Number displays.

11. Displays remaining life, in months.

12. All segments flash for 6 seconds indicating zeroing.

13. The working display is shown.

If the Snifit+ is in an area that is not gas free, “BAD” will
illuminate after the automatic zeroing followed by a read­ing based on factory zero set points.

BUMP TEST

To verify the operation of the instrument, a bump test
should be done prior to each day’s use. Bump test failure
may indicate a product failure or the need for calibration.

To perform a bump test, turn on the Snifit+ and wait for
the working display to be shown. Apply test gas using the
calibration adapter. Flow should be 200-400 cc/min. As­suming an alarm setpoint is less than the applied gas con­centration, an alarm should occur in less than 20 seconds.

OPERATION OVERVIEW

WARNING: Follow federal, state, local and com-

pany regulations as they relate to the use of this
product.

PLACEMENT: Attach the Snifit+ to the outermost garment
as close to your head/face as practical.

ALARMS: Alarms will indicate unsafe levels. The display
will show concentration data in combination with audible,
visual and vibration indications. TWA alarms can be
acknowledged for 10-minute intervals by pressing either
button.

MANUAL ZERO: Manual zeroing should only be done in an
atmosphere known to be CO gas free and containing nor­mal oxygen levels. Press for 2-3 seconds and release. All
segments of the display will flash followed by the working
display.

OVER RANGE: Exposure to CO gas in excess of 2000 ppm
will result in “OL” being displayed with the high alarm
activated.

OPERATION TIME: To view the remaining operation time,
press for 2-3 seconds and release. The Snifit



+ will dis-

play the time remaining in months, then perform a zero.

BATTERY DIAGNOSTICS: BAT indicates low battery output
and service will be needed soon.

WARNING: Only factory
should perform any internal servicing.

BAT + LO indicates that the Snifit+ should be immediately
taken out of service.

SYSTEM DIAGNOSTICS: I2C indicates a communication
error in the EEPROM. Factory service is required.

WARNING:
should perform any internal servicing.

SHUTDOWN: To turn off, press and hold the POWER but­ton ( ) for approximately 6 seconds until “OFF” is dis­played, then release the button. The Snifit



+ cannot be

powered off (or zeroed) when in alarm mode.
