CAUTION: The Triplett Sniff-It 2 does NOT detect DC Voltage

Safety Precautions and Warnings

1) Always test the Sniff-It 2 using a known AC voltage source, before

using it to determine if a circuit or object is “live”. Failure to observe

this precaution may result in user injury.

2) The Sniff-It 2 may not detect the presence of AC voltage in all

situations. Use caution and good work practices at all times, even when

the Sniff-It 2 indicates that AC voltage is not present. Failure to observe

this precaution may result in user injury.

3) The Sniff-It 2 may detect the presence of AC voltage when none

appears to be present. If testing for potentially dangerous AC voltages

(like 120VAC, 240VAC, 480VAC, etc), and the Sniff-It 2 seems to be

indicating that a circuit or object that should be grounded is “live”, use

extreme caution. Its possible that the user is “live”, and coming in

contact with a ground may cause user injury. This situation most often

occurs in house trailers or construction site trailers.

4) Do not place your finger, or any other object that you are holding, near

the tip when trying to use the Sniff-It 2. Doing so can interfere with the

sensing ability of the Sniff-It 2, making a “live” circuit seem “dead”.

Failure to observe this precaution may result in user injury.

Installing Battery

Remove the black pocket clip to expose the battery compartment. Insert

the battery with its negative side towards the tip of the Sniff-It 2. Replace

the pocket clip.

General Operation

Rotate the Sensitivity knob from its off position to its operating position.

When first turned on, the Sniff-It 2 is at its minimum sensitivity. Rotating

the knob will increase its sensitivity. When first turned on, the Sniff-It 2

must flash and chirp momentarily, either once or several times. If this

does not happen, check the battery for proper polarity, and/or replace the

battery with a fresh one. The Power Beeper will cause the beeper to chirp

and the LED to flash slowly while the Sniff-It 2 is turned on. This verifies

that the battery is OK, and reminds the user that the Sniff-It 2 is on and

operating.

The ability of the Sniff-It 2 to detect AC voltage is affected by both distance

and the magnitude of the voltage. That is, to detect a low voltage, it is

generally necessary for the tip of the Sniff-It 2 to be close to the voltage,

and the Sensitivity knob rotated towards higher sensitivity. A high voltage

can be detected at a distance. It is common practice to adjust the sensitiv-

ity so that the Sniff-It 2 responds to the voltage when the tip is close to or

touching the voltage source. This way, the user can “home in” on the source

of the voltage.

To set the Sensitivity knob properly, it is best to have a known source of

the target voltage available. Rotate the knob while holding the tip of the

Sniff-It 2 to the source of known voltage. When the Sniff-It 2 starts chirp-

ing and flashing quickly, stop rotating the knob. Slowly pull the tip of the

Sniff-It 2 away from the voltage source noting how the speed of the flash-

ing and chirping slows as the tip is removed from the source.

The Sniff-It 2 is now properly adjusted to detect a voltage similar to the

known voltage, or a higher voltage. It will not detect a significantly lower

voltage. Do not rotate the Sensitivity knob unless turning the product off,

or resetting the sensitivity.

The Sensitivity knob can be adjusted without the use of a known voltage,

but this requires user experience, and presents the possibility that the

knob may be misadjusted, or the product may not function, even though it

appears to be working. If using this technique, it is usually best to set the

knob to its maximum sensitivity first, so that even low voltages will be

detected, and then to “back off” the adjustment as necessary.

Note:

Due to the high sensitivity of the Sniff-It 2’s circuitry, it may appear to

detect voltage when the tip is rubbed or bumped, or when the tip is moved

around against a surface or in the air. For example, if the Sniff-It 2 is turned

on and placed in a shirt pocket, it may chirp and flash in a manner sug-

gesting that it has detected voltage, as the user moves or walks around.

WARNING!!!

If using the Sniff-It 2 without testing on a known voltage source, the Sniff-

It 2 may fail to chirp or flash when a “live” circuit or object is tested. Take

precautions to prevent user injury in the event that the tested circuit or

object is unexpectedly “live”.

WARNING!!!

The Sniff-It 2, like all similar products, may not detect AC voltage under all

circumstances. This is rare, but possible. To reduce the possibility of this

occurring, move the tip of the Sniff-It 2 back and forth, or up and down,

between any suspect circuits or objects when no voltage is detected. This

may move the tip outside of the “null field” and may allow detection of the

voltage.

WARNING!!!

The Sniff-It 2, like all similar products, may detect a GROUND instead of

AC voltage. This is rare, but possible. If the Sniff-It 2 appears to detecting

a ground instead of a “live” circuit or object, use extreme caution. The

user may be “live”, and touching a grounded circuit or object may result in

user injury.

Checking 120VAC Outlets for Proper Polarity

The following test is not conclusive. If Sniff-It 2 detects a problem, test

the outlet using conventional means (a meter, test plug, etc.). This test

can only be performed on a “live” outlet.

Test the Sniff-It 2 on a known 120VAC source before performing the polar-

ity test.

Turn on the Sniff-It 2 and insert the tip into the small slot of the 120VAC

receptacle. Slowly rotate the Sensitivity knob until the Sniff-It 2 just be-

gins to chirp and flash rapidly. Remove the tip from the small slot and

insert it into the large slot. The Sniff-It 2 must chirp and flash much more

slowly than when its tip is in the small slot. If it flashes rapidly, the outlet

may be wired incorrectly (Hot and Neutral may be reversed). Remove the

tip from the large slot and insert it (as far as possible) into the Ground

opening. The Sniff-It 2 must chirp and flash much more slowly than when

its tip is in the small slot. If it flashes rapidly, the outlet may be wired

incorrectly (the Ground may be incorrectly wired or not connected).

Checking Light Bulb Sockets for Unexpected Voltage

Light bulb sockets are sometimes wired incorrectly. While the light may

turn on and off when the wall switch is operated, there may be dangerous

voltage at the socket even when the switch is off. This can happen when

the light bulb circuit is incorrectly wired, or when the circuit is a old “3

way” type (new 3 way wiring should not allow a “live” bulb when the light

is off). This can pose a danger to someone changing a light bulb, who may

be accidentally shocked and injured by this unexpected voltage.

Turn on the Sniff-It 2 and set its sensitivity using a known 120VAC source.

Turn off the light switch. Remove the light bulb from its socket. Place the

tip of the Sniff-It 2 into the socket. The Sniff-It 2 must continue to chirp

and flash slowly. If it begins chirping and flashing faster, AC voltage is

present. Use caution. A shock hazard is present.
