Description
The JL3PR Job Link® System Pressure
Probe sends long range wireless pressure
measurements directly to the Fieldpiece Job
Link® system mobile app.
Easily reach service ports in tight spaces
using the angled 1/4" tting. The rubberized
protective housing is both ergonomic and
rugged for daily use.
Flip the switch to red or blue and the app
immediately knows which side of the system
you're going to place your pressure probe.
The perfect balance of size and capability
gives you exactly what you need to diagnose
systems day in and day out quickly and
condently.
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
yellow battery cover. Install 2 x AAA batteries.
You can also monitor battery life in the Job Link®
app tool manager.
GASKET: The black rubber gasket that seals
the pressure probe to the service port may
become worn over time potentially causing
a leak. This results from overtightening or
connecting to damaged service port ttings.
1 Use needle nose pliers or a similar tool to
unscrew the Schrader valve depressor from
the gasket.
2 Remove and replace the worn gasket.
3 Screw the depressor back into the gasket.
