ADJUSTMENT
Provides an ozone source for assessing the span
calibration and reducing the warm up time of sensors
You will need:
-
R71
S500 or R950
Reference ozone monitor
Ozone sensor under test
1)
Perform a zero check with the R70 and
possible adjustment prior to span adjustment
2)
Warm up the R71 for at least 60 minutes prior
to use
3)
Warm up the ozone sensor under test and
your reference sensor for at least 60 minutes.
Using the S500 key pad, scroll down to menu item
“ADJUSTMENT”
2)
Fully insert your reference sensor into the R71
as shown below to determine the R71 output.
Wait 10-15 minutes for a stable reading to be
obtained. Note down this reading – it is the
R71 output.

SPAN ADJUSTMENT
2)
Press and hold down the left hand and right hand
bottom buttons on the keypad for 2 seconds (see
above) to display the ZERO ADJUSTMENT and SPAN
ADJUSTMENT menu items.
3)
Change the ‘Gain Factor’ value (see equation below
for calculating the new Gain Factor).
Old gain factor
New gain factor =
1
Note: ozone output from the R71 varies under
differing temperature and humidity conditions

4)
Insert your ozone sensor under test into the
R71 as shown. Wait 10 to 15 minutes for a
stable reading to be obtained.
If the ozone sensor test deviates more than
10% from the reference sensor reading, the
ozone sensor span should be adjusted.

Ozone Fixed Monitors: Span assessment
Description
Span assessment
Span adjustment
1)
Install the supplied S900 configuration software
on your computer, then connect your fixed
monitor to computer (serial to USB)
If the ozone sensor test deviates more than 10% from the
reference sensor reading, the ozone sensor span should be
adjusted. To do so, the following process must be followed:
2)
Attach the tubing and appropriate fittings to the
‘Reference’ fixed monitor as below:
1)
Run the configuration software, selecting “Span
Adjustment.”
Flow from R71
Provides an ozone source for assessing the span
calibration and reducing the warm up time of sensors
You will need:
-
R71
Fixed monitor with new ‘Reference’ industrial
ozone sensor
Ozone sensor under test
Supplied fittings and teflon tubing
1)
Perform a zero check with the R70 and
possible adjustment prior to span adjustment
2)
Warm up the R71 for at least 60 minutes prior
to use
3)
Warm up the ozone sensor under test and
your reference sensor for at least 60 minutes.
Note: ozone output from the R71 varies under
differing temperature and humidity conditions
Flow from R71
3)
Select an ozone output level. To assess a low
ozone head, use a flat head screwdriver to move
the internal switch and select the low lamp.
3)
Wait for 10-15 minutes for a stable reading to be
obtained. Note this reading, it is the R71 output.
4)
If your fixed monitor does not have a display, run
the configuration software on your computer and
select “Check readings”
2)
In order to perform a span adjustment users will be
prompted to change the ‘Gain Factor’. To understand
where the gain factor should be set, follow the formula
below:
