3. Commissioning
3.1. Introduction
Commissioning the instrument can takes up to a couple of hours and is
conducted as follows :
•
Power Supply Voltage Selection :
No selection is necessary.
•
Applying Power :
Switching the power on and observing the
power supply rail indications.
•
Alignment :
Optically aligning the transmitter and receiver units
using the integral adjustable mount.*
•
Gain Adjustment :
Adjusting the gain within the receiver head
and the signal processor.*
•
Calibration :
Calibrate to a zero, or a known opacity level.*
•
Operating Parameters :
Setting the operating parameters within
the micro-processor to provide correct instrument operation.
•
Recording the Set-up and Calibration Data :
It is strongly
recommended that the operating parameters are recorded in the
table at 3.7.3. Example 2 : Dust Monitor and the calibration data in
the table at 3.8. Calibration Data.
* Preferably conducted when a clean stack condition exists.
These commissioning procedures are now examined in detail.
3.2. Turning the Power On
Switch the power on. Ensure that the power indication LED’s illuminate. If not,
check the fuse and the supply.
Replace the lid of the processor but do not fully tighten the signal processor
screws until after commissioning. The instrument will automatically select the
normal display mode.
