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.
Stick Meter
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:
AAV3 Air Velocity and Temperature
ADMN2 Dual-Port Manometer
AVG2 Digital Vacuum Gauge
AOX2 Combustion Check
Standalone Instruments
The SRL2 is a standalone instrument for leak
detection. Accessory heads do not hook up to it.
Below is a sampling of other standalone (non-mod-
ular) instruments available from Fieldpiece.

Lithium Battery Care
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 chargers 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 dissassemble or try to repair battery or
protective circuitry.
13.The battery is technician-replaceable and must
be sent to Fieldpiece Instruments if a replace-
ment is needed. It is not user-replaceable.
Charging
Two chargers 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.
Carrying Case
While both chargers fit in the included case, the
carrying case is intended to carry the leak detector
alone. Most users leave the chargers near the
power supply and carry around just the meter.
Larger cases, to hold both chargers plus extra
accessories, are available such as the ANC8 (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.
Optional Accessories
Use model RRE2 when detecting in tight spaces,
such as through a condensor grille. Model RFE2
extends the wand to 25.5”. The midsize case,
model ANC8, holds everything with room to spare.
