8.4 Proof tests
It is neccessary to do proof tests to make sure that the safety function is applicable to the full
measuring range.
• The device settings must be correct. If a parameter is incorrect, the device will not measure
correctly.
• The electronic components must not be defective.
• The software programs (firmware etc.) must operate correctly.
• The probe must correctly transmit and receive the measurement signal. Parasitic signals
must not have an effect on the performance of the device.
We recommend that you do a proof test immediately after you install and start the device.
Prepare the device for the proof tests. Do a check of the device parameters.
INFORMATION!
For more precise information, please contact your local sales office.
WARNING!
SIS engineers must calculate the interval of proof tests. The minimum time between proof tests
must be less than 5 years, but the interval between proof tests must also agree with the safety
system used on site.
CAUTION!
• Proof tests done by the customer must be equivalent or more difficult than the tests given in
this section.
• Keep a report of each proof test. These reports must include the date, the tests results
(performance of the safety function or faults found), a list of approved personnel who did the
test and the report revision number. These reports must be put into storage and made easily
available. A proof test report form (for copying) is available on page 32
.
• The location of the device and how it is installed on the tank can have an effect on the
performance. Make sure that you obey the installation instructions given in the handbook.
