If any problem appears which cannot be solved with the help of this user manual, contact our sales office and give a pre-
cise description of the problem. Specify the type, the serial number and the firmware version of the transmitter.
Calibration
FLUXUS is a very reliable instrument. It is manufactured under strict quality control, using modern production techniques.
If installed as recommended in an appropriate location, used cautiously and taken care of conscientiously, no troubles
should appear. The transmitter has been calibrated at the factory and, usually, a re-calibration of the transmitter will not be
necessary. A re-calibration is recommended if
• the contact surface of the transducers shows visible wear or
• the transducers were used for a prolonged period of time at a high temperature (several months >130 °C for normal
transducers or > 200 °C for high-temperature transducers).
The transmitter has to be sent to FLEXIM for recalibration under reference conditions.
The display does not work at all or fails regularly
Check the contrast setting of the transmitter (see section 14.4).
Make sure that the correct voltage is available at the terminals. The voltage is indicated on the metal plate below the outer
right terminal. If the power supply is ok, the transducers or an internal component of the transmitter are defective. 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 in the lower line. Track down the situations when the error
is displayed. Contact FLEXIM.
The transmitter does not react when key BRK is pressed during the measurement
A program code has been defined. Press key C and enter the program code.
The backlight of the display does not work, but all other functions are available.
The backlight is defective. This problem does not affect the other functions of the display. Send the transmitter to FLEXIM
for repair.
The display in the lower line constantly toggles between different physical quantities
Automatic toggling of the display in the BTU mode is activated. For the deactivation of the automatic toggling see section
16.3.5.
Date and time are wrong, the measured values are deleted when the transmitter is switched off
The data backup battery has to be replaced. Send the transmitter to FLEXIM.
An output does not work
Make sure that the outputs are configured correctly. Check the function of the output as described in section 18.1.3. If the
output is defective, contact FLEXIM.
A measurement is impossible or the measured values substantially differ from the expected values
see section 19.1.
The values of the totalizer are wrong
see section 19.6.
