3. USING THE FOUR FUNCTION BUTTONS:
Switching
ON the
Analyser
Press / button to switch the unit ON . This must
be done in fresh air to ensure that the analyser auto calibrates
its’ sensors properly.
When switched on, the analyser beeps twice and briefly
displays battery %, fuel and pressure units. Its’ bottom line
counts down from 60 until the sensors are ready to use. If the
analyser will not auto calibrate, its’ sensors need to be replaced
or recalibrated by an authorised repair centre.
If an inlet temperature probe (optional) is connected into the T2
socket during its’ countdown, the measured temperature from
the inlet probe will be used as the inlet temperature.
If an inlet temperature probe is not connected to the analyser
during countdown the measured temperature from the flue
probe will be used as the inlet temperature.
If neither probe is connected during countdown the analyser’s
internal ambient temperature will be used as the inlet
temperature.
Switching
OFF the
Analyser
Press / button to switch the analyser OFF. The
display counts down from 30 with the pump on to clear the
sensors with fresh air – If the probe is still connected, make
sure analyser and probe are in fresh air.
Press / if you want to stop the countdown and
return to making measurements.
Note: The analyser will not switch off unless the CO
reading is below 20ppm.
