Quick-Start Instructions
HINT: As you approach the source of the
leak, keep dialing down the rate of the
audible “tick” by dialing down the thumb
wheel which is located on the right side of
the instrument.
IMPORTANT: When replacing the
gooseneck into the clip on the right side,
wrap the gooseneck in a wide circular
manner counter-clockwise around the back
of the instrument. Bending in the opposite
direction may cause damage over the life of
the product.
WARNINGS:
To prevent ignition of ammable or combustible
atmospheres, disconnect power before servicing.
To reduce the risk of ignition of a ammable
atmosphere, batteries must only be changed in
an area known to be nonammable.
Do not mix batteries of different age or type.
ONLY zero instrument in a gas free environment.
To maintain intrinsic safety, service must be
performed by factory authorized technicians
with approved replacement parts only.
This is not a substitute for the
instruction manual. It is for
reference only.
Read and understand the
instruction manual before use.

1. Install the batteries by pushing down
the locking tab and sliding the handle
away from the top of the instrument. When
replacing handle be sure the tab is securely
in place.
2. IMPORTANT: CAREFULLY OBSERVE
POLARITY WHEN CHANGING BATTERIES.
Incorrect installation can damage an internal
“factory service only” fuse.
3. Locate button “A” – push & hold until the
unit powers up, then release the power button.
4. Allow unit to go through the warm up
sequence in clean air. At the end of warm
up, the unit will auto zero and enter the
working display. This requires from 40 up
to180 seconds.
5. If FAIL is displayed for any of the sensor
readings, make sure the instrument is in
clean air; push and hold the “C” button until
AUTO ZERO is displayed. If this process
does not clear the fail on the display, this
could indicate a problem with the instrument
or sensor.
6. Look at the display – PPM and LEL
readings are displayed.
7. Extend the goose neck (the PPM/LEL sensor
and cap is at the tip).
8. You are now ready to use the instrument.
You can now enter the area and detect gases.
9. Once the environment is determined to
be safe to work in, if the source of an odor
needs to be located, the thumb wheel can
be rotated to be heard at a comfortable tick
rate. Once an investigation is begun, as the
instrument is moved closer to a combustible
source, the tick rate will increase. The
thumb wheel can then be rotated back to
the comfortable rate and the investigation
continued until the source is located.
10. Press and hold the “C” button to zero the
instrument. (only in a gas free area).
11. When your investigation is complete,
roll the thumb wheel back down and click it
to the off position, push button “A” and hold
for 5 seconds until the instrument displays
“POWER OFF” then release to shut off.
