Maintenance
CLEANING: Clean the exterior with a damp
cloth. Do not use detergents or solvents. Do not
apply pressurized air into the connection port.
BATTERIES: When the LED slow-blinks Red,
the batteries must be replaced. Ensure the
power is OFF. Remove the single screw from the
yellow battery cover. Install 2 x AAA batteries.
You can also monitor battery life in the Job Link
app tool manager.
SENSOR CARE: Store JL3MN in a protective
cover when not in use to prevent debris or
foreign contaminants from entering the barb
tip. Do not pressurize the probe above its max
specication.

Description
The JL3MN Job Link® System Manometer
Probe sends static pressure or gas pressure
measurements directly to the Fieldpiece Job
Link app up to 350 feet (107 meters) away.
Use two JL3MN probes to do even more.
Because they are untethered, you don't need
long hoses to measure dierential pressures.
Measure and view real-time return static,
supply static, and total external static pressure
all at once. Use your static pressure tip with
short tubing for accurate static pressure
measurements. Measure real-time inlet and
manifold pressures simultaneously with 2 Job
Link manometers.
Mount your manometer to equipment for
hands free use in tight spaces. The powerful
rotating magnet holds tight even when the hose
is tugged or the equipment shakes. Slide the
switch and the app immediately knows which
side of the system you're going to place your
manometer probe.
WARNING
Prevent damage, do not drill holes blindly into a plenum that
houses the evaporator or heat exchanger.
Do not place any part of the manometer on hot surfaces such
as exhaust fumes. Doing so can cause personal injury, damage
equipment, and void warranty.
Do no apply more than 11.6 psi.
