information codes in accordance with NE107:

• M (warning) = maintenance required
• C (warning) = function check
• S (warning) = out of specification (deviations from the permitted ambient or process conditions
determined by the device with the self-monitoring function, or errors in the device itself indicate
that the measuring uncertainty is greater than what would be expected under normal operating
conditions).
