- The pressure measured by the digtal manifold pressure tester is gauge pressure.
- Pressure testing ranges from -101Kpa to 6Mpa (-0.1bar to 60bar).
- The limit pressure is 10 Mpa (100 bar).
- The maximum operating pressure of standard hose is 600 PSI ( approximate 4.13 Mpa, 41.3 bar ).
- The limit pressure is 3000 PSI approximate 20.68 Mpa, 206.8 bar ).
- Please confirm the rated pressure value of the tested equipment before testing.
- Do not use it if it exceeds the range of the instrument.
- Do not use and store the instrument in high temperature, high humidity, flammable, explosive and strong electromagnetic fields.
- Please do not change the instrument internal circuit, to avoid any damage of the instrument or danger occurring.
