DescriptionThe

SR

L2 uses

infrared optics

to create

aportable refrigerant leak detector technology thathas a superior com

bination of sensitivity, speed,sensor life, battery life, portability, and ease of use.

Gas is pum

ped through the tip of the wand into

the sensor

within

the S

RL2

body. The

sensordetects changes in concentration, not absolute con-centration, m

aking it easy to detect leaks even inareas w

ith refrigerant in the air. The S

RL2 detects leaks as sm

all as 0.1 oz/year,w

hich exceeds the toughest SA

E J1627 standards.

The SR

L2 comes w

ith wall and car chargers for its

ultra-compact Li-ion polym

er battery which pow

ersthe S

RL2 for 8hrs of continuous operation before a

recharge is needed. That’s long enough to last yourentire w

orkday.U

nlike many leak detectors, oil vapor does not

trigger the SR

L2.The S

RL2 has vari-

able sensitivity

set-tings,

keeping ‘nui-

sance tripping’

to a

minim

um. A

quick andautom

atic 30 second self-calibration upon power-up

ensures optimal perform

ance. Abuilt in replaceable

filter blocks moisture and harm

ful particulates. TheS

RL2 also has a m

ute button and a peak hold func-tion.

Leak Detection Procedure

Keep the S

RL2 aw

ay from any areas of potential

refrigerant leakage until the warm

-up and calibrationperiod

is over.

The w

arm-up

and calibration

sequence lasts about 30 seconds after ON

/OFF is

pressed. On startup, m

eter defaults to high sensitiv-ity.The m

ost likely points for refrigerant leaks are atthe soldered joints in refrigerant lines and changesin cross section or direction of these lines.

The SR

L2 detects changesin concentration of

refrigerant, not the absolute concentration of refrig-erant. This lets the user easily detect leaks in placesthat m

ay have refrigerant in the air, such as a refrig-erator leaking into an enclosed space. B

ecause theS

RL2 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 w

ithin 1/4” of a small

leak to detect it. In this case, using a secondhand to guide the tip along refrigerant lines m

aybe helpful.

2. Keep the tip m

oving along refrigerant lines at arate of 1-3 inches per second.

3. Once the S

RL2 indicates a change in concentra-

tion, note the spot on the line and keep the tipm

oving past the potential leak to refresh the airspace w

ithin the SR

L2 with clean air. (N

ote: Ifthe S

RL2 w

and 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 S

RL2.)

4. Return the tip back to, and past, the spot first

indicated. When the S

RL2 indicates a second

change, note the spot on the line. The source ofthe leak w

ill be near the midpoint betw

een thetw

o noted spots of indication. 5. Very high concentrations of refrigerant can

cause an overload which can take a few

sec-onds to clear.

Lithium

Battery C

areThe S

RL2 contains a very pow

erful two-cell lithi-

um ion polym

er battery. For a long battery life andsafe operation you m

ust observe the following:

Cautions

1. Charge only w

hile battery is inside the SR

L2w

ith a Fieldpiece supplied charger. Do not

charge externally. 2. D

o not expose the battery to temperatures high-

er than 140ºF. 3. D

o not charge the battery in or nearby heatedplaces, such as fire, hot vehicles, or direct sun-light.

4. Do not directly connect the battery to any bat-

tery charger. The included chargers connect tothe S

RL2, not the S

RL2 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 im

pact orthrow

it. If the protection circuit on the battery isbroken, do not continue to use the battery.

8. Do not get the battery w

et.9. D

o not deform or pierce the battery in any w

ay. 10. If there is any battery leakage, do not touch

the battery. In the case that electrolyte gets intothe eyes, flush w

ith fresh water, do not rub, and

see a physician imm

ediately. 11. S

end in for replacement im

mediately if there is

any deformity, bad sm

ell, color change, or otherabnorm

ality.12. D

o not dissassemble or try to repair battery or

protective circuitry.13.The battery is technician-replaceable and m

ustbe sent to Fieldpiece Instrum

entsif a replace-

ment is needed. It is not user-replaceable.

ChargingTw

o chargers are included with the S

RL2. The

AC

charger plugs into a wall outlet (110-120 VA

C,

60Hz) and the car charger plugs into a car cigarette

lighter DC

plug.1. The battery is partially charged w

hen packaged.Fully charge the battery before first use.

2. The LOW

-BATT

LED

will light red w

hen the bat-tery is low

. 3. To recharge the S

RL2, plug one end of the

charger into the top of the SR

L2 and the otherinto the pow

er source. LOW

-BATT

will blink

while charging until the battery is fully charged.

When the S

RL2 battery is fully charged, LO

W-

BATT

turns off. 4. C

harge within operating environm

ent specifiedin the Specifications section in this m

anual. 5. Avoid frequent full discharges. S

everal partialdischarges w

ith frequent recharges are betterfor lithium

-ion batteries. Unlike nickel-based bat-

teries they have no charge mem

ory, and do notneed to be discharged before charging.

StorageThe battery should have a 40%

-50% charge dur-

ing prolonged storage of a month or longer. S

eeSpecifications section in this m

anual for proper stor-age environm

ent. B

attery life is dramatically reduced if the battery

is stored fully charged and/or at high temperatures.

Carrying C

ase W

hile both chargers fit in the included case, thecarrying case is intended to carry the leak detectoralone. M

ost users leave the chargers near thepow

er supply and carry around just the meter.

Larger cases, to hold both chargers plus extraaccessories, are available such as the A

NC

8 (seeO

ptional Accessories).

FilterAssessm

ent & R

eplacement

The filter blocks moisture and other contam

inantsfrom

the sensor. When it gets w

et, it constricts flowof air and it w

ill have to be replaced.Unscrew

thesensor tip and replace the w

hite filter so that therounded end is closest to the tip of the w

and. Use

only the Fieldpiece supplied filter. E

xtra bags of replacement parts (m

odel RFL2)

are available from Fieldpiece w

hich contain 10filters and 5 O

-rings.
