If there is no
communication between
Communication Board
and Pressure Sensor
Board (Meter-body) or
invalid data on
communication line due to
noise
User can verify the
cable/connector
between communication
and Pressure sensor
board (Meter body) to
ensure that it is not
damaged.Check for bent
pins.If cable/connector is
not the problem, replace
the Communication
module.If problem still
persists, replace the
meter body.

and Temperature Sensor
Board (Terminal) or invalid
data on communication
line due to noise
User can verify the
cable/connector
between communication
and Temperature sensor
board (Terminal Board)
to ensure that it is not
damaged.Check for bent

Power cycle the device.
If problem persist, Check
the terminal voltage to
be within limits. If still
problem persists replace
the Terminal block
assembly. If problem
continues replace the
Communication module
