4.1.8 CO above 15ppm (Failsafe) Protection Beep
The 712 will not allow the user to either Turn the instrument OFF or to move to
another Function whilst the CO level is above 15ppm. A short beep will be heard
should the user attempt either of the above with the CO above 15ppm.
This is a Failsafe Feature of the 712 to protect the instrument from giving false
readings when next turned on. The 712 should be run in a clean air environment
with just the In-Line Pump Protection Filter attached until the CO level drops
below 15ppm. The 712 will then be able to be moved to a different function
screen or be turned OFF.
4.2 Function 2: - Temperature Reading
The pump will stop running when in this function
Remember:-

Ensure you have a ‘K’ type probe connected to one or both of the
thermocouple sockets ch1 or ch2 (see 4.2)
