Infrared
Refrigerant
Leak Detector
Model: SRL2
OPERATOR’S MANUAL
Description
The SRL2 uses infrared optics to create a
portable refrigerant leak detector technology that
has a superior combination of sensitivity, speed,
sensor life, battery life, portability, and ease of use.
Gas is pumped through the tip of the wand into
the sensor within the SRL2 body. The sensor
detects changes in concentration, not absolute con-
centration, making it easy to detect leaks even in
areas with refrigerant in the air.
The SRL2 detects leaks as small as 0.1 oz/year,
which exceeds the toughest SAE J1627 standards.
The SRL2 comes with wall and car charger for its
ultra-compact Li-ion polymer battery which powers
the SRL2 for 8hrs of continuous operation before a
recharge is needed. That’s long enough to last your
entire workday.
Unlike many leak detectors, oil vapor does not
trigger the SRL2.
The SRL2 has vari-
able sensitivity set-
tings, keeping ‘nui-
sance tripping’ to a
minimum. A quick and
automatic 30 second self-calibration upon power-up
ensures optimal performance. A built in replaceable
filter blocks moisture and harmful particulates. The
SRL2 also has a mute button and a peak hold func-
tion.

Operation
ON/OFF Protection
To turn on/off the SRL2 press and hold the
ON/OFF button for one second. This slight delay
protects against inadvertent pressing. If you forget
to turn it off, it will automatically go off in 10 minutes.
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.
L/M/H Button (Sensitivity)
Set the sensitivity level by pressing the L/M/H but-
ton. Low(L), medium(M), or high(H) sensitivity will
be indicated by their respective LED.
The higher the concentration of refrigerant in the
ambient air, the lower the sensitivity setting should
be to minimize false trips.
Mute Button
Pressing the MUTE button toggles the sound of
the SRL2 on and off.
Peak Button
The PEAK function holds the highest change in
concentration achieved while continuing to detect
leaks. Press PEAK to toggle this function on and off.
Turning the PEAK function off will clear the peak
change. The PEAK LED will light when PEAK func-
tion is on.
Turbo Mode
The TURBO function is an additional 4th sensitiv-
ity that pushes the SRL2 to it highest possible sen-
sitivity. This feature is activated by pressing the
PEAK button four times in succession, and can only
be activated while on the high(H) sensitivity level.
When in the TURBO mode the first green LED on
SRL2 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 SRL2 is
extremely sensitive and may trigger on abrupt or
violent motions as well as very small changes in
refrigerant levels. Handle with care when in TURBO
mode.
Leak Detection Procedure
Keep the SRL2 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 ON/OFF is
pressed. Allow the SRL2 to fully warm-up before
using to avoid false triggering. On startup, meter
defaults to high sensitivity.
The most likely points for refrigerant leaks are at
the soldered joints in refrigerant lines and changes
in cross section or direction of these lines.
The SRL2 detects changes in concentration of
refrigerant, not the absolute concentration of refrig-
erant. This lets the user easily detect leaks in places
that may have refrigerant in the air, such as a refrig-
erator leaking into an enclosed space. Because the
SRL2 detects change, there is a specific “double-
pass” method used to find leaks.
1. The tip of the wand should be fairly close to the
line. You may need to be within 1/4” of a small
leak to detect it. In this case, using a second
hand to guide the tip along refrigerant lines may
be helpful.
2. Keep the tip moving along refrigerant lines at a
rate of 1-3 inches per second.
3. Once the SRL2 indicates a change in concentra-
tion, note the spot on the line and keep the tip
moving past the potential leak to refresh the air
space within the SRL2 with clean air. (Note: If
the SRL2 wand moves through a very high con-
centration of refrigerant, you may need to use in
fresh air for 4 seconds before moving to step 4
in order to clear the refrigerant within the SRL2.)
4. Return the tip back to, and past, the spot first
indicated. When the SRL2 indicates a second
change, note the spot on the line. The source of
the leak will be 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.

Modular Expandability
Modular expandability is ability for accessory
heads and meters to change configurations to
match the various needs of an HVAC/R technician.
Accessory heads (the sensors) send out a mV
signal, which represents the value of the measure-
ment, to whatever meter is attached to it. Heads can
attach directly to the top of a Stick meter, DL2 data
logger, or EHDL1. They can also plug into any meter
with mV ranges using ASLS2 leads.

This is the heart of modular expandability. In addi-
tion to being a full functioning multimeter, any acces-
sory head can be used with it.

Accessory Heads
Accessory heads are the sensors of multiple
parameters measured by technicians every day.
They plug into a mV range (depending on the head)
of a multimeter. The multimeter will display whatev-
er the head is measuring. Instead of having to pur-
chase and carry a separate instrument for each
parameter, a technician can use multiple heads and
a single multimeter to do the job.
Here are four of the many heads available:

The SRL2 contains a very powerful two-cell lithi-
um ion polymer battery. For a long battery life and
safe operation you must observe the following:
Cautions
1. Charge only while battery is inside the SRL2
with a Fieldpiece supplied charger. Do not
charge externally.
2. Do not expose the battery to temperatures high-
er than 140ºF.
3. Do not charge the battery in or nearby heated
places, such as fire, hot vehicles, or direct sun-
light.
4. Do not directly connect the battery to any bat-
tery charger. The included charger connect to
the SRL2, not the SRL2 battery.
5. Do not solder directly on battery.
6. Do not use the battery for unspecified equip-
ment.
7. Do not expose the battery to direct impact or
throw it. If the protection circuit on the battery is
broken, do not continue to use the battery.
8. Do not get the battery wet.
9. Do not deform or pierce the battery in any way.
10. If there is any battery leakage, do not touch
the battery. In the case that electrolyte gets into
the eyes, flush with fresh water, do not rub, and
see a physician immediately.
11. Send in for replacement immediately if there is
any deformity, bad smell, color change, or other
abnormality.
12. Do not disassemble or try to repair battery or
protective circuitry.
13.The battery is technician-replaceable and must
be sent to Fieldpiece Instrumentsif a replace-
ment is needed. It is not user-replaceable.
Charging
Two charger are included with the SRL2. The AC
charger plugs into a wall outlet (110-120 VAC,
60Hz) and the car charger plugs into a car cigarette
lighter DC plug.
1. The battery is partially charged when packaged.
Fully charge the battery before first use.
2. The LOW-BATT LED will light red when the bat-
tery is low.
3. To recharge the SRL2, plug one end of the
charger into the top of the SRL2 and the other
into the power source. LOW-BATT will blink
while charging until the battery is fully charged.
When the SRL2 battery is fully charged, LOW-
BATT turns off.
4. Charge within operating environment specified
in the Specifications section in this manual.
5. Avoid frequent full discharges. Several partial
discharges with frequent recharges are better
for lithium-ion batteries. Unlike nickel-based bat-
teries they have no charge memory, and do not
need to be discharged before charging.
Storage
The battery should have a 40%-50% charge dur-
ing prolonged storage of a month or longer. See
Specifications section in this manual for proper stor-
age environment.
Battery life is dramatically reduced if the battery
is stored fully charged and/or at high temperatures.
Cloth Carrying Case
While both charger fit in the included case, the
carrying case is intended to carry the leak detector
alone. Most users leave the charger near the power
supply and carry around just the meter. Larger
cases, to hold both charger plus extra accessories,
are available such as the ABMK3 (see Optional
Accessories).
Filter Assessment & Replacement
The filter blocks moisture and other contaminants
from the sensor. When it gets wet, it constricts flow
of air and it 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 filter.
Extra bags of replacement parts (model RFL2)
are available from Fieldpiece which contain 10
filters and 5 O-rings.
Use model RRE2 when detecting in tight spaces,
such as through a condenser grille. Model RFE2
extends the wand to 25.5”. The Blow Mold case,
model ABMK3, holds accessories and chargers.
All accessories shown are included with the
SRL2K7.

ment.
7. Do not expose the battery to direct impact or
throw it. If the protection circuit on the battery is
broken, do not continue to use the battery.
8. Do not get the battery wet.
9. Do not deform or pierce the battery in any way.
10. If there is any battery leakage, do not touch
the battery. In the case that electrolyte gets into
the eyes, flush with fresh water, do not rub, and
see a physician immediately.
11. Send in for replacement immediately if there is
any deformity, bad smell, color change, or other
abnormality.
12. Do not disassemble or try to repair battery or
protective circuitry.
13.The battery is technician-replaceable and must
be sent to Fieldpiece Instrumentsif a replace-
ment is needed. It is not user-replaceable.
Charging
Two charger are included with the SRL2. The AC
charger plugs into a wall outlet (110-120 VAC,
60Hz) and the car charger plugs into a car cigarette
lighter DC plug.
1. The battery is partially charged when packaged.
Fully charge the battery before first use.
2. The LOW-BATT LED will light red when the bat-
tery is low.
3. To recharge the SRL2, plug one end of the
charger into the top of the SRL2 and the other
into the power source. LOW-BATT will blink
while charging until the battery is fully charged.
When the SRL2 battery is fully charged, LOW-
BATT turns off.
4. Charge within operating environment specified
in the Specifications section in this manual.
5. Avoid frequent full discharges. Several partial
discharges with frequent recharges are better
for lithium-ion batteries. Unlike nickel-based bat-
teries they have no charge memory, and do not
need to be discharged before charging.
Storage
The battery should have a 40%-50% charge dur-
ing prolonged storage of a month or longer. See
Specifications section in this manual for proper stor-
age environment.
Battery life is dramatically reduced if the battery
is stored fully charged and/or at high temperatures.
Cloth Carrying Case
While both charger fit in the included case, the
carrying case is intended to carry the leak detector
alone. Most users leave the charger near the power
supply and carry around just the meter. Larger
cases, to hold both charger plus extra accessories,
are available such as the ABMK3 (see Optional
Accessories).
Filter Assessment & Replacement
The filter blocks moisture and other contaminants
from the sensor. When it gets wet, it constricts flow
of air and it 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 filter.
Extra bags of replacement parts (model RFL2)
are available from Fieldpiece which contain 10
filters and 5 O-rings.
Use model RRE2 when detecting in tight spaces,
such as through a condenser grille. Model RFE2
extends the wand to 25.5”. The Blow Mold case,
model ABMK3, holds accessories and chargers.
All accessories shown are included with the
SRL2K7.
