Description
The JL3PC Job Link™ Premium Pipe Clamp
Probe sends long range wireless pipe temperature measurements directly to the Fieldpiece
Job Link™ mobile app. Take advantage of the
Rapid Rail™ sensor for extremely fast and accurate measurements that surpasses California's
Title 24 requirements.
The Rapid Rail™ sensor is specifically
designed to work on HVACR electrically (and
thermally) conductive piping. It uses the pipe
itself to complete the circuit so ambient air
does not affect testing, resulting in the highest
temperature accuracy!
Navigate cramped spaces using the narrow
jaw. Rubberized grips and ergonomic design
supply comfort and control. Work on a wide
range of pipes from ¼’’ to 1-3/8’’. Pipe diameters are etched into sides of the clamp for quick
reference.
What's Included

FCC Statement
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
. Reorient or relocate the receiving antenna.
. Increase the separation between the equipment and receiver.
. Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: To assure continued compliance, any changes or
modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
(Example - use only shielded interface cables when connecting to computer or peripheral devices).
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.

Operation
Press for 1 second to power ON/OFF.
LED Color Indications
Green slow blink: normal operation
Yellow blink: open thermocouple circuit
JL3PC requires electrical continuity with the
pipe. Clean pipe surface if necessary.
Red slow blink: batteries need to be replaced
High or Low Side Switch
The Job Link™ app knows which side you
have selected for each probe. Select Suction
line or Liquid line and place it on the system
appropriately.
Rapid Rail™ Sensor Advantage
Traditional pipe clamps sit on top of the pipe
surface. Some sensors touch the pipe, some
have a material between the pipe and the
sensor. Those sensors can be affected by wind,
heat, corrosion, insulation, paint, dirt, etc.
The Rapid Rail™ sensor uses the pipe itself to
complete the thermocouple circuit. The pipe is
part of the sensor! If you get a measurement,
you know it's accurate.
Because the pipe is the thermocouple
junction, all you need is enough contact for
conductivity. This means the clamp can sit on an
angle or on a bend without loss in performance.
There is a beeper and an LED to indicate
whether or not the circuit is closed and a temperature is being measured:
Double beep and yellow LED = Open Circuit
Single beep and green LED = Closed Circuit
If you don't get a measurement, there's
something on the pipe that's blocking the electrical circuit (and accuracy). Sometimes you can
slightly rotate the clamp back and forth around
the pipe to cut through contaminants. Sometimes you need to clean the pipe a bit with
emery cloth.
Remote Data Logging
(Data logging will be available shortly after
time of printing. Look for Job Link™ app updates.)
Use the Job Link™ app to program the JL3PC
to log measurements starting at a specific time
of day for up to 7 days. Auto power off disables.
1 Make sure JL3PC is powered OFF.
2 Open the Job Link™ app.
3 Press on JL3PC for 5 seconds to enter data
logging mode. The LED will shine solid green.
4 Set up the probe's data logging parameters
within the app. The LED will blink green while
the app is sending setup instructions. The
LED will slow blink blue when waiting for
programmed start time to occur.
5 Place the JL3PC on the system.
6 When the programmed start time is reached,
the LED will very slowly blink green to indicate
data logging has begun.
7 When the programmed span has finished, the
LED blinks and powers OFF.
8 Repeat steps 1-3 and use the Job Link™ app
to extract your data log from the JL3PC.
Auto Power Off (APO)
If the clamp hasn't been opened/closed or
the button pressed, it will automatically power
off after 2 hours. To disable APO until powered
off, while power is on tap twice. The LED will
briefly blink red. To enable APO, while power
is on tap
twice. The LED will briefly shine red.
Maintenance
CLEANING: Clean the exterior with a damp
cloth. Do not use detergents or solvents.
BATTERIES: When the LED slow blinks Red,
the batteries must be replaced. Ensure the
power is OFF. Remove the single screw from
the top rubberized battery cover. Install 2 x AAA
batteries. You can also monitor batter y life in
the Job Link™ app tool manager.
CALIBRATION: The JL3PC is wireless so it
doesn't need to be calibrated as often as wired
thermocouples. To verify accuracy, submerge
just the sensor into ice water. Depending on
atmospheric pressure and water purity, the
measurement will be 32°F ± 1°F. If calibration is
required, use the tool manager in the Job Link™
app to adjust the offset for that particular tool.
