Set the factor of Mass Concentration Conversion Coefficient (K
FACTOR).
Move the cursor to K FACTOR and press [SET] key to highlight the
value. Press [

0.0001.
The range of the settable factor is 0.0001 ~ 0.0099.
Select a value for K FACTOR, and then press [SET] key.
The factor will stop being highlighted.

To convert the value indicated by the instrument into the mass concentration (mg/m

3

) the Mass Concentration

Conversion Coefficient (K factor) shall be obtained. The K-factor is determined by performing a parallel measurement
based on a filtration instrument which uses particle size analyzer.

How to obtain K-factor is as follows:
Prepare the instrument (Model 3443) and a filtration instrument which uses a particle size analyzer. When placing
these two units, keep their suction direction and the height of the suction points same. Select “MANUAL” mode on
the instrument and start measuring using those units at the same time. To calculate K-factor, divide the mass
concentration (C) measured by the filtration instrument by the count per minute (R). In order to obtain (R) divide the
count you get using this instrument by the measurement time (min).

K = C/R

To convert the factor into mass concentration (mg/m

3

), multiply the K-factor by CPM that you obtain at each

measurement point using this instrument.

* The ranges of corresponding value of mass concentration are 0 to 10,000 counts. The counts above the
range won

’

t be converted accurately.

*

The settable factor range is K = 0.0001 ~ 0.0099.

*

Before shipping, 1 CPM = 0.0010 mg/m

3

is assigned for

calibration particle. Therefore, K factor is set to 0.0010.

*

Example:

K = 0.0010: 100 CPM

→

0.1 mg/m

3

K = 0.0020: 100 CPM

→

0.2 mg/m
