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.
