How can I check the operation of a Vigilohm XM200?

To check that a Vigilohm XM200 is operating correctly:

• Disconnect terminal 4 from the line supply (value indicated: 999).
• Connect terminal 4 to terminal 11. If R=0 then the Vigilohm is operating correctly.
• If R=999 remains displayed permanently, the Vigilohm XM200 is faulty.

Please note that the XM200 version of the Vigiohm range is no longer produced, please search for the Vigiohm range for an alternative.
