LS-R912
The combination of test pressure ranges of 2 circuits (Inlet-A/Inlet-B) can be chosen from the support table below.
Of the combinations of various pressure ranges, choose two types that meet your demands from the table below.
Test 1 location Test pressure 2 ranges
Test 3 locations Test pressure 2 ranges
Pressure is applied to the workpiece.
If you push the button above, it will be shifted to the following button for easy fine tuning of the pressure.
During setup, a large numeric keypad appears, and all types of settings can be adjusted using the simple screen display.
Regarding the convenient functions of the LS-R902 which are included in the LS-R912, please consult the LS-R902 page.
