WARRANTY POLICY

a) Disconnect both pressure tubes from the pressure ports labeled

+ and –.

b) Push down the zero button (joystick) until the LED light (red)

turns on and the display reads “zeroing” (display option only). (see

Figure 6)

c) The zeroing of the device will proceed automatically. Zeroing is

complete when the LED turns off, and the display reads 0 (display

option only).

d) Reinstall the pressure tubes, ensuring the High pressure tube is

connected to the port labeled +, and the Low pressure tube is

connected to the port labeled −.
