To change the calibration factor for the flow meter, select
Fm
from the Cal Menu and push the
Function
Knob. The submenu will appear:
Fm Cal Menu
Fm= 0.92
This is a multiplicative factor that will increase the flow rate if you increase the value. Adjust this value
to correct the flow value when comparing it to a calibrated volumetric flow meter connected to the inlet
of the instrument.
To change the calibration factors for the ozone measurement, select
O3
from the Cal Menu and push
the
Function
Knob. The submenu will appear:
Cal Menu
Z= -3 S= 1.01
Z
is the offset applied (in this case -3 ppb) and
S
is the slope applied (in this case 1.01). The value of
Z
is added to the measured ozone value, and the value of
S
is then multiplied by the measured ozone
value. During calibration,
Z
is set to 0 and
S
is set to 1.00. If the instrument reads an average of 3 ppb
with the external scrubber in place, the value of
Z
should be set to -3. If after correction for the zero, the
instrument consistently reads 2% low (in the presence of a precisely known ozone concentration), the
value of
S
should be set to 1.02.
To change a value, rotate the knob to move the cursor to the value you want to change, push the knob
to activate the value, rotate the knob to change the value, and then push the knob again to store the
value. You may then rotate the knob to select a different value and repeat the process.
