a rate of 1-3 inches (2.5-7.5cm) per second.
3 Once the SCL2 indicates a change in concen-
tration (audible beep), note the spot on the
lineandkeepthetipmovingpastthepotential
leak to refresh the air space within the SCL2
with clean air. (Note: If the SCL2 wand moves
throughaveryhighconcentrationofrefriger-
ant, you may need to use it in fresh air for 4
seconds before moving to step 4 in order to
clear the refrigerant within the SCL2.)
4 Return the tip back across the spot rst in-
dicated. When the SCL2 indicates a second
change, note the spot on the line.The source
oftheleakwillbe near the midpoint between
the two noted spots of indication.
5 Very high concentrations of refrigerant can
cause an overload which can take a few sec-
onds to clear.
Quick Start
1 Charge the SCL2 (see charging instructions
on page 14 for details).
2 Power on SCL2 and allow a 30 second warm
up to complete in well ventilated ambient air
away from suspected leak.
3 Select the sensitivity using the L/M/H button.
4 Point the tip of the wand at suspected leak
locations(seeFindCO2Leakssectionon page
4 for details).
Quick Tips
1 Keep the wand tip moving slowly past sus-
pected leak locations.
2 Once a leak is detected, sweep the wand back
over to pinpoint.
3 To pinpoint larger leaks adjust sensitivity.

Description
The SCL2 is a portable CO2 (R-744) leak
detector with a superior combination of
sensitivity, speed, sensor life, battery life,
portability, and ease of use.
Find leaks on commercial refrigeration
systems, restaurant soda machines, or any other
system using R-744. Pinpoint tiny leaks in high
concentration CO2 environments with ease.
Gas is pumped through the tip of the wand
into the sensor within the SCL2 body. The sensor
detects changes in concentration, not absolute
concentration, allowing the SCL2 to dierentiate
CO2 concentrations higher than concentrations
normally found in ambient air.
The SCL2 detects leaks as small as 6 grams/
yr (0.2 oz/yr). The SCL2 has three sensitivity
settings to keep false triggering to a minimum.
A quick and automatic 30 second self-calibration
upon power-up ensures optimal performance.
The SCL2 comes with a wall and car charger
for its ultra-compact lithium-ion battery
which powers the SCL2 for 8hrs of continuous
operation before a recharge is needed. That's
long enough to last your entire workday.
A built-in replaceable lter blocks moisture
and harmful particulates.
Find CO2 Leaks
Keep the SCL2 away from any areas of
potential refrigerant leakage until the warm-up
and calibration period is over.The warm-up and
calibration sequence lasts about 30 seconds
after powered on. Allow the SCL2 to fully warm-
up before searching for CO2 leaks to avoid false
triggering.The meter defaults to high sensitivity.
The most likely points for refrigerant leaks
are at the soldered joints in refrigerant lines
and changes in the cross section or direction
of these lines.
The SCL2 detects changes in concentration of
CO2, not the absolute concentration.This helps
you to detect CO2 leaks in places that may have
lots of CO2, such as a refrigerator leaking into
an enclosed space. Because you are detecting
a change in concentration, you should use the
"double-pass" method detailed below.
1 Thetipof thewand shouldbe closetotheline.
You may need to be within 1/4” (0.63cm) of
a small leak to detect it. In this case, using a
secondhandtoguidethetipalong refrigerant
lines may be helpful. See Figure 1.

When in TURBO mode the rst green LED on
SCL2 will strobe, and the audio detection sound
will be a solid tone.
To exit the TURBO mode, press the PEAK
button again four times in succession, or switch
from high(H) to one of the other sensitivities
levels.
Beware: While in TURBO mode the SCL2 is
extremely sensitive and will more easily trigger
on abrupt or violent motions as well as very
small changes in refrigerant levels. Handle with
care when in TURBO mode.
LED Indicators
LED Bar Graph Display
The eight segment LED display indicates the degree of change
in refrigerant concentration. As the concentration of refrigerant
in the air increases, so does the number of lit bars on the display.
Low-Batt LED
1 While detector is in use, the Low-Batt LED will turn solid red
indicating approximately 1 hour of battery life left.
2 While detector is charging, the Low-Batt LED will ash red on
and o indicating the meter is charging.
3 When detector is fully charged, the Low-Batt LED will turn o
indicating the meter is fully charged.
H/M/L LEDs
High (red), medium (amber) , or low (green)
LED will turn solid indicating what sensitivity
is selected.

The blow molded case, model holds accessories
and chargers.
All accessories shown are included with the
SCL2.
Lithium Battery Care
The SCL2 contains a very powerful lithium
ion battery. For a long battery life and safe
operation, you must observe the following:
Cautions
1 Do not expose the battery to temperatures
higher than 140ºF (60°C).
2 Donot charge the battery in or nearby heated
places, such as re, hot vehicles, or direct
sunlight.
3 Do not solder directly onto the battery.
4 Do not expose the battery to direct impact or
throw it.
5 Do not get the battery wet.
6Do not deform or pierce the battery in any way.
7 If there is any battery leakage, do not touch
the battery. In the case that electrolyte gets
into the eyes, ush with fresh water, do not
rub, and see a physician immediately.
8 Replace immediately if there is any deformity,
badsmell,colorchange,orotherabnormality.
9The battery is user-replaceable and can be
purchased at most electronic stores. The fol-
lowing batteries are known to be compatible
withtheSCL2:FujiFilm:NP-120,PENTAX:DLI-7,
RICON: DB-43
Charging
Two chargers are included with the SCL2.
The AC charger plugs into a wall outlet and the
car charger plugs into a car cigarette lighter DC
plug.
1 The battery is partially charged when pack-
aged. Fully charge the battery before rst use.
2 The LOW-BATT LED will light red when the
battery is low.
3 To recharge the SCL2, plug one end of the
charger into the top of the SCL2 and the
other into the power source. LOW-BATT
will blink while charging until the battery is
fully charged. When the SCL2 battery is fully
charged, LOW-BATT turns o.
4Charge within operating environment speci-
ed in the Specications section on page 11.
5Avoid frequent full discharges. Several partial
dischargeswithfrequentrechargesarebetter
for lithium-ion batteries. Unlike nickel-based
batteries they have no charge memory, and
donotneedtobe dischargedbeforecharging.
Storage
The battery should have a 40%-50% charge
during prolonged storage of a month or longer.
See Specications section in this manual for
proper storage environment.
Battery life is dramatically reduced if the
battery is stored fully charged and/or at high
temperatures.
Maintenance
Clean the exterior with a dry cloth. Do not
use liquid.
Filter Assessment & Replacement
The filter blocks moisture and other
contaminants from the sensor. When it gets
wet, it constricts ow of air and will have to be
replaced. Unscrew the sensor tip and replace
the white filter so that the rounded end is
closest to the tip of the wand. Use only the
Fieldpiece supplied lter.
You can order extra bags of replacement
parts (Part# RFL2) from your local distributor.
