Frequently Asked Questions
■ The pressure display or output value does not change after pressurization (mostly
displayed as 0 or FULL ) or the change is not accurate.
(1) Whether the loading pressure exceeds the burst pressure and directly breaks the
pressure core.
(2) Whether the medium used is corrosive or differs from the applicable medium of the
purchased product.
(3) Check whether the intake hose is blocked by foreign matter (particulate matter or
water column) or leaks.
(4) Whether the use environment temperature exceeds the compensation temperature
range.
(5) Whether there is a misoperation of clearing during pressurization, if any, clear again
after confirming that there is no input pressure.
■ A slight drift in the zero pressure value
After the drift is stable, perform the reset operation.
■ Attention
(1) The power supply should be disconnected during the installation process, and the
power interface should not be short-circuited, otherwise it will bring unpredictable conse-
quences and even damage the product.
(2) Please use within the rated voltage range.
(3) Do not make the pressure exceed the withstand pressure value, otherwise it may
damage the product and safety.
(4) Some unused output wires need to be wrapped with insulating tape to avoid possible
short circuits.
