Operation and Maintenance Manual
Introduction
This series of gauges is designed for use on today’s modern heavy equipment machinery.
They are tough, water resistant, and easy to use. What makes these gauges better than
conventional digital gauges is that they are wireless and can display pressure differential as
well as individual pressures.
The wireless function is accomplished with the use of a 915MHz RF module, which is
powerful enough to be hundreds of meters away even when the transmitter is locked in the
pump compartment. To ensure accuracy and stability these reading are taken seven times,
averaged, and sent to the display every half second.
Safety Information
•Read all safety information before you use the Product.
•Carefully read all instructions.
•Do not alter the Product and use only as specified, or the protection supplied by the
Product can be compromised.
•Battery:
•The battery door must be closed and secured before you using the Product.
•Replace the batteries when the low battery indicator shows to prevent incorrect
measurements.
•To avoid leakage remove the batteries if the unit is to be stored for extended
periods of time of if stored in high temperature areas (over 50 °C).
•Repair the Product before use if the battery leaks.
•Be sure that the battery polarity is correct to prevent battery leakage.
•If the Product is exposed to overpressure or sudden physical shock (such as a drop),
examine the Product for damage that can cause a safety concern. If necessary, return
the Product to KPFM for evaluation.
•Always apply thread seal tape or liquid to the threads of the gauge.
•Do not over torque the test port fittings. Maximum torque allowed is 34 Nm = 25 ft lbs.
•Hydraulic Pressure:
•Fluids and gasses under pressure can cause serious injury or death
•Use all appropriate PPE for the Fluids and pressures you are working with.
Including but not limited to gloves and safety glasses
•Never connect or disconnect fittings under pressure
•For directions on how to bleed down the pressure on component to be tested
consult the appropriate manufactures manuals.
•Never check for Hydraulic leaks with your hands. High pressure can cut the skin
