STATUS/ERROR/WARNING MESSAGES

There are three types of message that will appear and they are Status, Error and Warning. These messages appear under the
time and date on the display when in flow mode.

5.1

Status messages

5.1.1

S1: Initialising

Appears when first entering flow mode to show instrument is starting up.

5.1.2

S2: Logging to memory

This informs the user that the instrument is logging to the internal memory.

5.1.3

S3: Logging to RS232

This informs the user that the instrument is logging to an external device i.e. a printer.

5.2

Error messages

5.2.1

E1: Unstable or high flow

This error message occurs when either the sensors have been positioned too near to an obstruction or bend causing turbulence,
or the instrument is being used outside its normal flow range. When the instrument is programmed the user is informed of the
maximum flow rate that is possible to measure and if this is exceeded then the high flow message occurs. It may be possible to
get round these problems by moving the sensors to a straighter length of pipe or in the case of high flows another set of
transducers may be used.

5.2.2

E2: No flow signal

This message appears when the two transducers cannot send or receive signals, which could happen for various reasons. Firstly
check that all cables are connected, transducers are on the pipe correctly with grease on the face. These reasons could be when
trying to measure a partially empty pipe, aerated liquid or when the particulate content of that liquid is too high. It could also
happen if couplant has not been applied to the transducers or the condition of the pipe being measured is poor.

5.3

Warning messages

5.3.1

W1: Check site data

This message occurs when the application information has been entered incorrectly and the wrong sensors have been attached to
the wrong pipe size causing the timing to be in error. The site data needs to be checked and the instrument reprogrammed.
