Installation of the Ozone Monitor
To operate the Ozone Monitor, connect it to an external power source and turn the
instrument on by flipping the front panel switch. The instrument requires a 12 V DC
source which can be supplied by: 1) the 110-220 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 11-14 V DC
without any detrimental effects on the measurement. When using a battery, be certain
to attach the positive (red) and negative (black) wires correctly. 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 days. 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:

Once turned on, the instrument will display the version number of the software
installed on the microprocessor followed by a display of the time and date. After a few
seconds, the instrument will start displaying readings for ozone and the temperature
and pressure of the absorption cell. The first dozen 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 10-20 minutes required for the lamp, photodiode, and internal temperature of the
absorption cell to stabilize.
