Calibration
CALIBRATION
Testers are verified using 0 876 specific gravity, 150 SUS (32 cSt) Mobil / DTE 24 hydraulic oil An optional 5 or 10 point
calibration certificate, traceable to NIST, ISO 9001, is available from the factory An optional 10 point calibration can be
performed for increased accuracy

READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING THE TESTER. IF YOU HAVE ANY QUESTIONS REGARDING
PRODUCT INSTALLATION OR MAINTENANCE, CALL YOUR LOCAL SUPPLIER OR THE FACTORY FOR MORE INFORMATION.
General Information
The power measurements are derived from the product of flow and pressure

• Make all tests at the same operating temperature to provide consistency of results A typical operating temperature for
mobile machinery is 150° F (66° C)
• Testing is easier and faster if quick disconnect couplers are used to install the Flo-Check USB Hydraulic System Analyzer
• For complete descriptions of the following basic hydraulic tests using the Flo-Check USB Hydraulic System Analyzer, see
◊ "Tee" Test
◊ Inline System Test
◊ Control Valve and Bi-directional Hydraulic Motor Test
◊ Bi-Directional Cylinder Test
◊ Hydrostatic Transmission Diagnostics
THE INFORMATION IN THIS MANUAL IS FOR GENERAL APPLICATION ONLY. FOLLOW ANY INFORMATION FURNISHED BY
THE MANUFACTURER OF THE MACHINE’S HYDRAULIC COMPONENTS. SPECIFIC SYSTEMS MAY REQUIRE SPECIFIC
TEST PROCEDURES.
• Do a preliminary check of the hydraulic system’s oil supply, pump speed, oil lines and cylinder rods, as well as an external
leak check, prior to installing the Flo-Check USB Hydraulic System Analyzer
