In order to realize a recalibration under reference conditions either the transmitter, the
transducers or the transmitter with transducers have to be sent to FLEXIM depending on
which part needs to be calibrated.
The display does not work at all or fails regularly
Check the contrast setting of the transmitter or enter the HotCode
555000
to set the dis-
play to medium contrast.
Check that the battery is inserted and charged. Connect the power supply unit. If the
power supply is OK, the transducers or an internal component of the transmitter are de-
fective. The transducers and the transmitter have to be sent to FLEXIM for repair.
The message "SYSTEM ERROR" is displayed
Press key BRK to return to the main menu.
If this message is displayed repeatedly, write down the number displayed in the lower
line. Track down the situations when the error is displayed. Contact FLEXIM.
The backlight of the display does not work, but all other functions are available
The backlight is defective. This problem has no influence on other functions of the dis-
play. Send the transmitter to FLEXIM for repair.
Date and time are wrong, the measured values are deleted when the transmitter is
switched off
The data backup battery has to be replaced if the date and the time are reset or wrong or
the measured values are deleted after the transmitter has been switched off and on.
Send the transmitter to FLEXIM.
An output does not work
Make sure that the outputs are configured correctly. Check the function of the output. If
the output is defective, contact FLEXIM.

Problems with the measurement
A measurement is not possible because no signal is received. A question mark (
?
)
is displayed after the physical quantity.
• Check whether the entered parameters are correct, especially the outer pipe diameter,
the pipe wall thickness and the sound speed of the fluid. Typical errors: the circumfer-
ence or the radius was entered instead of the diameter. The inner pipe diameter was
entered instead of the outer pipe diameter.
• Check the number of sound paths.
• Make sure that the recommended transducer distance was adjusted when mounting
the transducers.
• Make sure that an appropriate measuring point is selected and the number of sound
paths was entered correctly.
• Try to establish a better acoustic contact between the pipe and the transducers.
• Enter a lower value for the number of sound paths. The signal attenuation might be too
high due to a high fluid viscosity or deposits on the inner pipe wall.
