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 tem-
perature 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 elec-
trical circuit (and accuracy). Sometimes you can
slightly rotate the clamp back and forth around
the pipe to cut through contaminants. Some-
times 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 battery 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.
