Instructions for using the portable hydraulic test unit
The tester is designed to measure pressure, flow, temperature and rpm. It can take full system
pressure between 210 and 480 bar (3000 and 7000 psi) depending on the model. It is capable
of measuring flow in both directions for motor and cylinder testing.
Make all tests at operating temperatures because as the oil temperature increases it becomes
thinner and any internal leakage becomes greater.
Testing will be easier and faster if quick disconnect couplers are used to attach the Test Unit.
There are two basic 'set-ups' when using the Tester.
a) The In Line test to check out pumps, entire systems and also monitoring operating
conditions.
b) The Tee Test to check out pumps, directional control valves and the overall system
condition.
A preliminary check of the hydraulic system's oil supply, pump rotation, filters, oil lines, cylinder
rods as well as looking for external leaks should be made prior to installing the Hydraulic Tester.
