SAFETY INFORMATION
WARNING: The Snifit
+ contains a lithium battery
which my leak or explode if improperly used. Do
not place the Snifit
not place the Snifit
+ in fire or incinerate.
IMPORTANT: Snifit
+ has no user-serviceable
parts inside. Do not disassemble the instrument.
IMPORTANT: Verify operation each day by per-
forming a functional (bump) test.
IMPORTANT: Keep all openings free of dirt,
debris, and foreign objects.
IMPORTANT: Do not use if damaged or improp-
erly operating. Contact a service representative
immediately.
IMPORTANT: Zero the Snifit
+ only in a CO-free
environment.
IMPORTANT: Dispose of the Snifit
+ properly.
DESCRIPTION
The Snifit
+ is a rugged personal gas monitor for detecting
carbon monoxide gas. Preset alarms provide visual, audi-
ble, and vibration alerts for low and high alarm conditions.
Built-in time weighted average (TWA) alarms and short-
term 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
+ from the rigors of
field use. The unit is sealed for an IP65 environmental
resistance rating.
Operation: Two buttons operate the Snifit
+ . The left
button ( ) is for power. The right ( ) is for zeroing and
calibrating. The Snifit
+ supports “continuous on” opera-
tion. The CO sensor and battery are designed for 2 years
of continuous normal use.
Sensor: The sensor opening is on the front of the Snifit
+ .
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
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.
FEATURES (CONTINUED)
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:
LOW:
35 ppm
TWA:
50 ppm
HIGH:
200 ppm
STEL:
75 ppm
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”.
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.
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.
1. All segments and icons will activate.
2. Gas type to be sensed will be displayed.
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 read-
ing 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. As-
suming an alarm setpoint is less than the applied gas con-
centration, an alarm should occur in less than 20 seconds.
