STEP 2 – Capture Process Information
Capture some representative information from the plant. It is essential that the plant is running normally during this time.
NOTE: Do not carry out this step on start-up or during a bag-cleaning cycle.
Figure 9: Setup procedure – Step 2
1. To begin collecting information, set the MODE slide switch to SET. The STATUS LED starts flashing to indicate that data
is being collected.
2. Run the data collection process as long as required (up to two hours maximum).
In general, a longer collection period will provide a more accurate representation of plant activity. However, 15 minutes is
typically sufficient to provide a good, representative sample.
NOTE: If the FFD sensor is to be referenced against an isokinetic sample, the collection period must be the same
length as the sample run.
STEP 3 – Determine the Dust Level
Using the rotary controls, determine the Dust level from the process data collected in STEP 2 above.
If the STATUS LED is flashing GREEN, do not adjust the lower control at this stage.
•
If the STATUS LED is flashing RED, proceed as follows:
•
1. Referring to Figure 10, turn the LOWER rotary control CW, step-by-step through each setting (×1, ×10, ...), until the
STATUS LED changes from flashing RED to flashing GREEN.

2. Then slowly turn the UPPER rotary control CCW, until the STATUS LED changes from flashing GREEN to flashing RED.
