    MYHT series hydraulic pressure tester use and maintenance: 

This section is only general instruction. Relevant information   provided by the manufacturer must be referred and specific systems such as Variable Pump or Motor or Serve Control Vale  have specific test program.

When MYHT - 1 Hydraulic Tester is installed at any position of hydraulic pipe, the hydraulic oil always flows from near the loading valves to the other end.  If reverse connect arises, no pressure will be formed. In order to obtain the accurate measurements, the oil inlet and oiloutlet of the tester keep away above30cm away from the elbow, tees, valve.

Note: The loading valve must be unscrew counterclockwise before start-up of the equipment. It will cause human injury or equipment damage if the loading valve is fully closed!!!!!!

Once the tester accessed with oil pipeline,  the pressure will be regulated by Loading Valve.

1)         Frigid climate will influence on the accuracy of measurement, so oil should be cycled some time before test.  Until the the temperature goes up to 30°C, the test shall be conducted.

After the completion of test, power switch should be turned off.
