Particulate Measurement System 4750-PM
4.6 Power-up Quick Check
To set up the system quickly, first ensure that the power to the sensor is ON
and that the purge air blower is also connected and ON.
1) On power-up, the display shows a two-part number, e.g.
17.55
where
•
17 – is number indicating that the sensor is a Type 4750-PM and
• 55 – is the installed software version, in this example v5.5
2) This is followed by 170, indicating a 4750-PM
3) Both status LEDs should be GREEN when the sensor is first switched
ON.
If the Purge Air Fail alarm is available and active and the self-check LED
is RED, this indicates that the air purge has failed. (If this option is not
available, the LED will remain GREEN as long as other self-checks are
successful, even if there is no air flow!)
The system installation is now complete, and the instrument is ready for
commissioning (i.e. setup and calibration).
