2.1 Operating the Sensor
The Honeywell EC-P2 is shipped ready for use. To power up the instrument, push
the PWR button. The power up sequence displays first the self check, the sensor
full scale value, the downscale caution level, warning concentration setpoint, alarm
concentration setpoint, output ranges, software version, then the normal operating
screen.
The unit will then display the instantaneous gas concentration and is ready for
use.
