Error messages
The
PipeCheck
plus
automatically detects and displays pipe connection errors (an
incorrect connection of the black measurement lines and the pipe connection
magnet to the medium pipe, see page 7), interruptions in the measuring loop as
well as errors due to element voltages.
Pipe connection errors
If a
pipe connection error
occurs (an
incorrect connection of the black measure-
ment lines and the pipe connection magnet
to the medium pipe, see page 7), the dis-
play will show the “No pipe contact” error
message.
The measurement will then be suspended
until the error is fixed.
Pressing the “Stop” soft key makes the dis-
play return to the measurement screen.
No measurement values will be shown.
Broken measurement loops
If a
measurement loop is interrupted
,
the display will show the “Loop interrupted”
error message.
Once the error is corrected, the determined
measurement value will be shown.
Contact between the pipe/measuring wire
If the display shows a “C” for “contact”
above the insulation resistance unit, this
could indicate a
metallic contact between
the medium pipe and measuring wire
.
Error message “Measuring wire mix up”
Only for HDW measurements!
Where wires a and b are mixed up due to
incorrect installation or incorrectly connect-
ed measurement lines, this will lead to
incorrect measurements.
The
PipeCheck
plus
will detect this kind of
error and show it on the display as “Loop interrupted” and “a<>b”.
