Operation of the Ozone Monitor
3.2.1
Powering the Instrument
To operate the Ozone Monitor, connect it to an external power source and power the
instrument on using the power switch. The instrument requires a 12 V DC source
which can be supplied by: 1) the 100-240 V AC power adapter, 2) a cigarette lighter
adapter plugged into a 12 V DC source such as found in an automobile or many light
aircraft, or 3) a 12 V battery. The source can be in the range 11-28 V DC without any
detrimental effects on the measurement. When using a battery, be certain to attach
the positi ve (red) and negative (black) wires correctly. Batteries and battery chargers
are available from 2B Technologies. A circuit breaker and diode are installed on the
circuit board in case of an electrical short or incorrect battery attachment. If activated,
the breaker will reset itself after a few minutes.
Lead-acid batteries are available from numerous manufacturers in a wide range of
sizes and amp-hour ratings. The larger of these, such as those for automobiles or
boats, will supply power for up to several weeks. Battery packs in the correct voltage
range may be constructed from nickel-cadmium (rechargeable) or lithium (lightweight
but not rechargeable) batteries for operation for a few hours. Battery options available
through 2B Technologies may be found on our webpage:

3.2.2
Initial Startup
Once turned on, the instrument will display the version number of the software
installed on the microprocessor. After a few seconds, the instrument will start
displaying readings for ozone. The first several readings (requiring about two
minutes) will be spurious, with large positive and negative swings due to the rapid
warmup of the lamp and electronics. Also, ozone readings may be inaccurate during
the first 20-30 minutes required for the lamp, photodiodes, and internal temperature of
the absorption cell to stabilize.
