[1] Feed zero gas to perform zero calibration.
See “5.4 Zero calibration” for details.
→
Check that the ozone concentration is
appropriate.
* If calibration is made in a state when zero gas
contains ozone gas, the measurement value
decreases.
[2] Decrease the ozone concentration.
→
Check the span setting and cell length setting.
[3] Feed zero gas and check the light intensity of
sensor 1 and that of sensor 2.
See “5.2.3 Check mode, (1) Sensor output check”
for details.
→
Check that the light intensity falls within the 500
to 4900 range.
See “9.5.2 How to adjust the sensor” for details.
[4] Check the following setting contents.
See “5.2.2 Setting mode” for details.
• Temperature/pressure compensation setting
(co)
• Offset setting (oFF)
• Span setting (SP)
• Cell length setting (cELL)
• Measured concentration unit setting (UnIT)
• Decimal point position setting (dP)
• Zero calibration mode setting (ZEro)
• Warm-up operation time setting (UP)

E1
Feed zero gas and check the light intensity of sensor
1 and that of sensor 2.
See “5.2.3 Check mode, (1) Sensor output check”
for details.
*Operated in 5 minutes after the power is turned on.
→
Mercury lamp or sensor error is considered.
Contact us if the symptom persists even after the
lamp is replaced with a new one.
E2
[1] Feed zero gas and perform zero calibration.
See “5.4 Zero calibration” for details.
→
Check that no ozone gas is contained.
[2] Feed zero gas and check the light intensity of
sensor 1 and that of sensor 2.
See “5.2.3 Check mode, (1) Sensor output check”
for details.
→
Cell contamination, or mercury lamp or sensor
error is considered. Contact us if the symptom
persists even after the lamp is replaced with a
new one.
E3
Feed zero gas and check the light intensity of sensor
1 and that of sensor 2.
See “5.2.3 Check mode, (1) Sensor output check”
for details.
*Operated in 5 minutes after the power is turned on.
→
Degradation of the mercury lamp or sensor error
is considered. Contact us if the symptom persists
even after the lamp is replaced with a new one.
E6 ON
Check that the interface cable is connected properly.
*Operated in 5 minutes after the power is turned on.
→
Turn off the power, reconnect the interface
cable, and restart the analyzer. Contact us if the
symptom persists.
E6 blink
Check that the interface cable is connected properly.
*Operated in 5 minutes after the power is turned on.
→
