Example 3 of one man calibration setup parameters
Min Conc.
Max Conc.
Settling Time (s)
Bottle
In this example the signal never stabilises so
the % function never operates and the system
does not calibrate.

Typical screen displays during calibration.
Although the person calibrating will not see the automated actions that the Tocsin 920 undertakes
during calibration anyone observing will see the following sequence taking place as gas is applied
to detectors.
First sensor has had gas applied and is
into the settling period.
Time left is displayed. If gas is not applied
to a sensor for more than 60 minutes then
the sequence times out and the system
returns to normal operation
Sensor has passed calibration. The system
will now wait for gas to be applied to the
next sensor.
The sequence is complete and the
number of calibrated sensors is
displayed. The operator should check
this matches the intended number of
sensors and then run the sensor check
function to check correct calibration
and functional status.
