Service FAQ’s

Where can I find my serial number?

Either on the back of the instrument or in the analytical software.

In the analytical software:

Click “help” then click “About”. Here you will find who it was sold to, the order number and serial number.

How can I identify my instrument model?

In the analytical software, click “help” then click “about”. Here you will find the model number.

Why is my instrument screen blue/black?

    This suggests that the monitor is not receiving a signal. Check that the monitor is connected and also check that the PC is “ON”.

Why are there white rings on my burn spots?

White burns mean poor argon/sample preperation.

  • Check a freshly prepared setting up sample (see section 5 of the User Guide)
  • Check the argon is of the correct grade and that the supply is on (see section 3.1 of the User Guide)
  • Check that the argon exhaust is not blocked
  • Make sure the instrument has had time to flush through
    (see section 3.10 in the ARTUS 8 Guide, 3.8 in the Neo and Junior Guide)

Why is there no bubbling sound?

  • Check the argon is on and the supply is OK
  • Check the exhaust is not blocked (see section 4 of the User Guide)

Why is my analysis incorrect?

  • Check the burns are good
  • Check the instrument is stabilised and that the profile is good (see section 3 of the User Guide)
  • Check user maintenance has been performed (see section 4.1 of the User Guide)
  • Check the metal has been sampled and prepared correctly (see section 5 of the User Guide)
  • Standardise the program being used (see section 4 of the A Plus Software Guide)

Why won’t my instrument start?

  • Check that the power and the unit are switched on
  • Restart the instrument and PC to ensure connection has been made

Why is there no argon flowing?

  • Check the argon is on and the supply is OK
  • Check the exhaust is not blocked (see section 4 of the User Guide)

Why won’t my instrument burn?

  • Check that the source is switched on
  • Restart the instrument and PC to ensure connection has been made

How/where can I replace my setting up samples?

Before the sample is too thin or beyond its useful life to use for the re-standardisation procedure; a replacement should be ordered. (see section 4.1 of the A Plus Software Guide).

Technical FAQs

Can grey, lamellar and nodular elements be analysed?

Yes. They must be chill cast down to white form, before being analysed. When these elements are chill cast, they are being made graphite-free. An analytical reading is then possible.

What is Chill Cast?

Iron-carbon alloy with low graphitization factor so that chill occurs forming a graphite-free structure. The carbon is present bonded in the form of iron carbide, which is why the break surface of the material appears whitish instead of grey. The carbides of the unalloyed types are ledeburite and cementite (Fe 3 C) or austenite with eutectoid decay (perlite).

How low a reading is obtainable on the CuNiZn curve as it relates to melted scrap that can have a nickel reading between 0.5 to 35%?

ARUN Technology has data for high and low CuNiZn readings in relation to nickel. These results are dependent on the concentration of metals in the sample.
