Do not apply over pressure or excessive voltage.
Please avoid excessive weight, Vibration, and impact to the transmitter.
It could cause the rupture, and the leaked fluid or material could be harmful to the environment.
Allowed Operating Temperature (Tamb = -20 ~ 80 °C)
Excessive temperature could cause the malfuction of the transmitter and measuring error.
If explosive gas is present, use correspoing enviromental entity approved products,
and do not disassemble or assemble the transmitter in such area.
Before disconnecting the transmitter, user must make sure that the valve is closed so the measuring fluid would not leak.
The leakage could cause the suffocation and explosion.
Installation of transmitter must be performed according to this manual.
Do not temper transmitter to add new function to it.
For repairing Purpose, please consult the manufacturer.

Shield Wire and outer surface is connected together, and Cable shield wire should be connected to Ground Terminal.
Ground Cable wire is AWG24, and in case of using Extension wire, the standard should be higher than Ground Wire standard.
In case of working on the terminal, to prevent the unwinding, use washer and to prevent the corrosion, use plated terminal and lug.
Ground point should be connected to rebar, floor, or Bus Bar.
(Ground Point should be considered with a local Industrial regulation, and Electric standards)

Working pressure should not be over 100 % of its Maximum pressure.
Do not apply overpressure.
Avoid sudden pressure or sudden decompression.
Scheduled examimation should be 1 or 2 times in every 6 months.
If measured pressure error is suspected, then detached the Transmitter for the examination.
If Transmitter is worn out, it is exposed to any other harsh environment, then the measuring error could be found,
it is recommended to replace the Transmitter.
Consult licensed Technician for repair to avoid fire, electric shock, or injury.
If requies Zero Adjustment, Use our Zero Trim Calibrator.
