5.0 Troubleshooting

Series 200/205

Fault Description

Possible cause

Remedy

No power

Lead connection broken

Power supply failure

Battery flat

S200 damaged

Sensor head damaged

Reconnect power lead

Replace 12V DC power supply

Recharge battery

Replace unit

Replace sensor head

Sensor failure
when the sensor
is new

Insufficient warm up

Air contaminated

Sensor damaged

Run the sensor on full power for
24-48 hours.

If an ozone source is available,
exposure to 100 ppb for 5 min-
utes will speed up the decon-
tamination process
(approximately 30 minutes)

Move the sensor to cleaner
environment and check reading

Replace sensor

Reading high
under zero gas
conditions

Background gas level higher
than normal

Interferent gas present

Sensor damaged

Move sensor to clean air and
recheck baseline

Move sensor to clean air and
recheck baseline

Replace sensor

Reading lower
than expected
reading in the
presence of sen-
sor gas

Sensor correct

Sensor inlet contaminated

Sensor fan failed

Interferent gas present

Gas reactive and decompos-
ing before detection

Local air flow too high (ozone
sensors) or
too low (VOC and ammonia
sensors)

Sensor calibration lost

Check calibration of gas genera-
tor.

Clean sensor inlet filter and
mesh

Replace sensor

Move sensor to clean air and
check reading upon exposure to
known gas concentration

Move the monitor closer to the
source of the gas

Modify the airflow into and
around sensor head.

Replace /refurbish sensor
